ABSTRACT: Delayed union and nonunion of fractures exist in the pediatric population. Fracture healing requires the synergistic collaboration of mechanical support and robust biological processes to allow endochondral ossification, reestablishment of bone continuity, and subsequent remodeling to strong lamellar bone. Failure of either mechanical stability or biology may manifest as delayed fracture healing. While early recognition of potential metabolic and pharmacologic risk factors may be addressed by pre-emptive treatment using nutritional and vitamin D supplements, definitive treatment of established nonunion requires a comprehensive approach. Key Concepts: (1) Delayed unions and nonunions are more common in adult bone but can also occur in pediatric bone. (2) Fracture healing requires synergistic collaboration of mechanical support and robust biological processes; treatment of nonunions should address both the biological and mechanical factors. (3) Vitamin D is an integral component of calcium absorption and bone health.

ABSTRACT: Background: Most children and adolescents who have flexible pes planovalgus (PPV) are asymptomatic, however some have significant daily foot pain that limits their activities. Current acceptable treatment options are conservative measures or full foot reconstruction and at present there is no “middle ground” treatment in the United States. The Subtalar Extra-Articular Screw Arthroereisis (SESA) (aka “calcaneo-stop”) procedure offers a minimally invasive option for PPV correction, and is done commonly in Europe with satisfactory results. Its not clear why this procedure has not yet been widely adopted in North America. The purpose of this study was to assess early single surgeon experience and patient satisfaction in North America with the SESA for treatment of flexible PPV. Methods: A single-center tertiary care departmental database was queried retrospectively to identify patients who had undergone treatment for PPV with SESA correction from 2018–2022. Patients and their caregivers were surveyed cross-sectionally for patient satisfaction and functional outcomes. Demographic, clinical, radiologic, and outcome data were summarized by patient and by foot. Changes in radiographic measurements were assessed using paired t-tests. Results: Thirty-seven feet (51% female) with PPV treated with SESA correction in 20 patients were analyzed at an average of 12 months (8–21 mo) after surgery. Average patient age was 13.3 years (SD, 2.3; Range, 9.4–18.8) at surgery. Concomitant procedures were done in 20 feet (63%), including 12 Achilles lengthenings, 5 accessory navicular excisions, 2 medial distal femoral hemiepiphysiodesis, and 1 hallux valgus correction. Mean radiographic improvement was seen from preoperative to postoperative: (1) standing anterior-posterior (SAP) talus-1st metatarsal angle of 14.6 degrees (P

- Abstract
Purpose: The purpose of this prospective study was to assess and compare clinical outcomes for patients with bilateral tarsal coalitions who had at least one coalition treated with surgical excision. Method: Patients were identified prospectively and agreed to participate. Data was collected prior to surgery, and again after surgery for up to 2 years. Comparisons of patients with unilateral disease to bilateral disease as well as unilateral excision to bilateral staggered and bilateral concomitant excision was done. Results: Initial cohort included 55 patients with 70 feet containing a tarsal coalition. 30 patients with 45 feet had bilateral tarsal coalition excision during the study period. Post-operative outcomes were considerably improved from preoperative outcomes. Five bilateral patients had concomitant excision, and ten had staggered surgery. There was no difference in outcome from patients with unilateral disease when compared to bilateral disease. There was no difference in patients with bilateral disease who had only one side excised compared to those that had both sides excised, and there was no difference in outcome for patients with staggered surgery compared to those with concomitant surgery. Conclusions: Patients with bilateral tarsal coalition show improvement in their outcomes in a similar fashion to those with unilateral disease. Concomitant surgical outcomes are comparable to staggered outcomes in this group, although the series is small.

Treatment of juvenile hallux valgus can be challenging. Initial treatment with conservative measures is appropriate until exhausted. Surgical treatment should be delayed until after skeletal maturity when possible. Before any intervention, a thorough understanding of the whole patient and any underlying systemic contributors to their hallux valgus, in addition to the radiographic foot parameters, is imperative. Careful and individualized surgical planning should be done to optimize results and decrease the risk for recurrence.

More than 1 in 4 pediatric fractures involves the distal radius. Most prior epidemiologic studies are limited to retrospective, single center investigations, and often include adults. This study aims to describe the contemporary epidemiology of pediatric distal radius fractures using prospectively collected data from a multicenter Pediatric Distal Radius Fracture Registry.Patients aged 4 to 18 years diagnosed with a distal radius fracture from June 2018 through December 2019 at 4 tertiary care pediatric centers were screened and enrolled in this prospective longitudinal cohort study. Patients were excluded if they presented with bilateral distal radius fractures, polytrauma, or re-fracture. Demographic information, mechanism of injury, fracture characteristics, associated injuries, and procedural information were recorded. All radiographs were reviewed and measured. Descriptive statistics and bivariate analyses were performed.A total of 1951 patients were included. The mean age was 9.9±3.3 years, and 61.3% of patients were male ( P0.001). Most injuries occurred during a high-energy fall (33.5%) or sports participation (28.4%). The greatest proportion of fractures occurred during the spring months (38.5%). Torus fractures (44.0%) were more common than bicortical (31.3%) or physeal (21.0%) fractures. Of the physeal fractures, 84.3% were Salter-Harris type II. Associated ulnar fractures were observed in 51.2% of patients. The mean age at injury was higher for patients with physeal fractures (11.6±2.9 y) than patients with torus or bicortical fractures (9.4±3.1 and 9.6±3.1 y, respectively; P0.001). Thirty-six percent of distal radius fractures underwent closed reduction and 3.3% underwent surgical fixation. Patients treated with closed reduction were more likely to be male (68.7% vs. 57.2%; P0.001), obese (25.3% vs. 17.2%; P0.001), and have bicortical fractures (62.2% vs. 14.5%; P0.001).Distal radius fractures in children have a male preponderance and are most likely to occur in the spring months and during high-energy falls and sports. Physeal fractures tend to occur in older children while torus and bicortical fractures tend to occur in younger children.Level I-prognostic.

Background: Challenges remain in determining which displaced supracondylar humerus fractures are safe to postpone surgical treatment until daylight hours. The purpose of this study is to determine which characteristics can be identified to guide the timing of treatment of supracondylar humerus fractures. Methods: 225 completely displaced Gartland extension type 3/4 supracondylar humerus fractures in healthy patients that presented between 6 am and 7 am were identified. Data were collected retrospectively. Data analysis included univariate, multivariable logistic regression and classification and regression tree analysis. Results: 5% (78/225) underwent surgical treatment the night they presented, while 65% (147/225) were treated the next day. Overall complication rate was 6%, with no difference based on timing of surgery. 12% (28/225) presented with a motor nerve injury, while 6% (14/225) a “pink pulseless” extremity. Statistical analysis found the most reliable radiographic predictor to be the maximum displacement on the anterior–posterior or lateral view. Classification and regression tree analysis developed a clinical algorithm; patients with a “pink pulseless” extremity or motor nerve injury were recommended for surgery overnight, while those with an anterior–posterior or lateral view Conclusion: This study provides guidance on the timing of treatment for displaced supracondylar humerus fractures that present overnight. We provide a simple algorithm with three key clinical predictors for timing of treatment: presence of a “pink pulseless” arm, presence of a motor nerve injury, and displacement of any cortex by at least 25 mm (anterior–posterior or lateral view). This provides a step forward to help practitioners make safer evidenced-based timing decisions for their patients. Level of evidence: Prognostic Study, Level II.

BACKGROUND Opioids are indicated for moderate-to-severe pain caused by trauma, ischemia, surgery, cancer and sickle cell disease, and vaso-occlusive episodes (SCD-VOC). There is only limited evidence regarding the appropriate number of doses to prescribe for specific indications. Therefore, we developed and implemented an opioid prescribing algorithm with dosing guidelines for specific procedures and conditions. We aimed to reach and sustain 90% compliance within 1 year of implementation. METHODS We conducted this quality improvement effort at a pediatric academic quaternary care institution. In 2018, a multidisciplinary team identified the need for a standard approach to opioid prescribing. The algorithm guides prescribers to evaluate the medical history, physical examination, red flags, pain type, and to initiate opioid-sparing interventions before prescribing opioids. Opioid prescriptions written between January 2015 and September 2020 were included. Examples from 2 hospital departments will be highlighted. Control charts for compliance with guidelines and variability in the doses prescribed are presented for selected procedures and conditions. RESULTS Over 5 years, 83 037 opioid prescriptions in 53 804 unique patients were entered electronically. The encounters with ≥1 opioid prescription decreased from 48% to 25% between 2015 and 2019. Compliance with the specific guidelines increased to ∼85% for periacetabular osteotomies and SCD-VOC and close to 100% for anterior-cruciate ligament surgery. In all 3 procedures and conditions, variability in the number of doses prescribed decreased significantly. CONCLUSION We developed an algorithm, guidelines, and a process for improvement. The number of opioid prescriptions and variability in opioid prescribing decreased. Future evaluation of specific initiatives within departments is needed.

Research has demonstrated similar efficacy of drill epiphysiodesis and percutaneous epiphysiodesis using transphyseal screws for the management of adolescent leg length discrepancy. A cost analysis was performed to determine which procedure is more cost-effective. Patients seen for epiphysiodesis of the distal femur and/or proximal tibia and fibula between 2004 and 2017 were reviewed. A decision analysis model was used to compare costs. Two hundred thirty-five patients who underwent either drill (155/235, 66%) or screw (80/235, 34%) epiphysiodesis were analyzed with an average age at initial procedure of 13 years (range, 8.4 to 16.7 years). There was no significant difference in average initial procedure cost or total cost of all procedures across treatment groups (n = 184). The cost difference between drill and screw epiphysiodesis is minimal. In order for screw epiphysiodesis to be cost-favored, there would need to be a significant decrease in its cost or complication rate. (Journal of Surgical Orthopaedic Advances 30(3):181-184, 2021).

Background Excision of pediatric tarsal coalition has been successful in most patients. However, some patients have ongoing pain after coalition excision. This study prospectively assessed patient-based clinical outcomes before and after surgical excision of tarsal coalition, with particular emphasis on comparison to radiologic imaging. Methods We prospectively studied 55 patients who had symptomatic coalition excision for 2 years postoperatively. Patients filled out the modified American Orthopaedic Foot and Ankle Society score, the University of California Los Angeles activity score, and the simple question "does foot pain limit your activity" at 4 different time points: preoperative, 6 months postoperative, 12 months postoperative, and 24 months postoperative. Comparisons were done utilizing patient demographics, imaging parameters, and patient-reported outcomes. Results Compared with preoperative levels, patients showed improvements in all outcome parameters. Patients with calcaneonavicular coalitions showed initial rapid improvement with later slight decline, while patients with talocalcaneal coalitions showed more steady improvement; both were similar at 2 years postoperatively. Conclusions This prospective study demonstrated remarkable clinical improvements after tarsal coalition excision regardless coalition type, though postoperative courses differed between calcaneonavicular and talocalcaneal types. Finally, a subset of patients has ongoing activity limiting foot pain after coalition excision which could not be explained by the data in this study. Level of evidence Level II-prospective cohort study.

Purpose The presence of a clubfoot is often found prenatally and some families seek counselling with a specialist. The purpose of this study was to compare the parental anxiety levels in families that: a) knew prenatally and had prenatal counselling; b) knew prenatally but did not seek prenatal counselling; and c) did not know until after delivery. Methods This prospective cohort study evaluated the anxiety of parents as they presented to the paediatric orthopaedic clinic with their newborn with a foot disorder (prior to the diagnostic confirmation of clubfoot). Each family filled out the ‘Pre-visit orthopaedic surgeon questionnaire’ and then after the initial visit with the orthopaedic surgeon (confirming the clubfoot diagnosis) the family filled out the ‘Immediately post-visit orthopaedic surgeon questionnaire’. Through these questionnaires, anxiety level was assessed prior to meeting postnatally with the paediatric orthopaedic specialist, as well as after the meeting and compared across groups. Results A total of 121 parents completed questionnaires: 71% (86/121) confirmed clubfoot; 69% of families (59/86) received prenatal counselling (Group A); 16% (14/86) knew prenatally but had no counselling (Group B); and 15% (13/86) found out at birth (Group C). There was no difference in anxiety levels across groups before (p = 0.78) or after (p = 0.57) meeting with the paediatric orthopaedic surgeon; however, overall anxiety reduced significantly (p < 0.001). Conclusion We found no difference in the anxiety levels of across the three groups. Prenatal counselling for parents of children with likely clubfoot may not decrease parental anxiety, but nonetheless is very appreciated by the families who receive it.

BACKGROUND: Reduction of variations may streamline healthcare delivery, improve patient outcomes, and minimize cost. The purpose of this study was to characterize variations in surgical rates and hospital costs for treatment of pediatric distal radius fractures (DRFs) using Pediatric Health Information System (PHIS) database. METHODS: The PHIS database was queried from 2009-2013 for DRFs in patients 4-18 years of age. Patients who underwent surgical treatment with internal fixation were identified using surgical CPT codes and/or ICD-9 procedure codes. 25 children’s hospitals were included. Surgical rates and hospital costs were modeled. Rates were adjusted and standardized for gender, age, presence of other diagnoses, and year. RESULTS: The aggregate rate of surgery for treatment of DRF was 2.65% and for open surgery was 0.81%. The standardized surgical rates for the 25 hospitals ranged widely, from 1.45% to 13.8% and for open surgical treatment from 0.51% to 4.27%. Six of the 25 hospitals had rates significantly higher than the aggregate for surgical treatment. Standardized hospital costs per patient ranged from $361 to $1,088 (2013 US dollars) across the hospitals with fairly uniform distribution. CONCLUSIONS: In the United States, there is great variability in practice and hospital costs of treatment of distal radius fractures. Further characterization of the root causes of these variations, and the effect, if any, on patient outcomes, is needed to improve value delivery in pediatric orthopaedic care. Level of Evidence: II

Background The purpose of this investigation was to compare the presentation and postoperative results of children treated for open and closed, completely displaced type III supracondylar humerus fractures (SCFs). Methods Thirty patients with open and 66 patients with closed, completely displaced type III SCFs were evaluated. Open fractures underwent irrigation and debridement, and all patients were treated by open or closed reduction and pin fixation. Medical records were reviewed to obtain demographic information as well as preoperative and postoperative clinical data regarding mechanism of injury, neurovascular status, associated injuries, postoperative range of motion, infections, and pain. Radiographs were evaluated to quantify displacement, Baumann's angle, humeral capitellar angle, position of the anterior humeral line, and adequacy of reduction. Outcomes were assessed using Flynn criteria. Mean clinical follow-up for the open and closed fracture groups was 8.9 and 5.7 months, respectively. Results Both groups were similar with respect to age, sex distribution, weight and body mass index, laterality of involvement, and mechanism of injury. At presentation, 35% of closed SCFs and 23% of open SCFs presented with abnormal neurovascular status. There was a higher prevalence of diminished/absent pulses or distal limb ischemia in patients with open injuries (27%) compared with closed fractures (18%). Conversely, severely displaced closed fractures were more commonly associated with nerve injury/palsy at presentation (35%) than those with open fractures (23%). Spontaneous nerve recovery was seen in 87% within 3 to 6 months. Postoperative loss of reduction and malunion were more common in the closed fracture group. However, 84% of patients achieved good-to-excellent results by Flynn criteria, with no appreciable difference based upon open versus closed fractures. Conclusions With timely wound and fracture treatment, the clinical and radiographic results of children treated for open SCFs is similar to those with closed type III injuries, with little increased risk for infection, malunion, or neurovascular compromise. Level of evidence Level III.

Purpose To compare two common surgical techniques of epiphysiodesis: drill/curettage epiphysiodesis (PDED) versus cross screw epiphysiodesis (PETS). The hypothesis is that the two techniques have similar efficacy but demonstrate differences in length of hospital stay (LOS), time to return to activity and complication rates. Methods A retrospective review of growing children and adolescents less than 18 years old who required an epiphysiodesis with leg-length discrepancy (LLD) of 2 cm to 6 cm with minimum two years of follow-up was conducted. Characteristics including age at surgery, gender, epiphysiodesis location, side, operative time, LOS and hardware removal were compared across treatment groups. LLD, expected growth remaining (EGR) and bone age were determined preoperatively and at most-recent visit. The correction ratio (change in EGR) was calculated along with a 95% confidence interval (CI) to assess if correction in leg length was achieved. Results A total of 115 patients underwent epiphysiodesis in the femur (53%), tibia (24%) or a combination (24%). The cohort was 47% male, with a mean age of 12.6 years (7.7 to 17.7) at surgery. Median follow-up was 3.7 years (2.0 to 12.7). In all, 23 patients underwent PETS and 92 patients had PDED. Both treatment groups achieved expected LLD correction. There was no significant difference in median operative time, complication rates or LOS. PETS patients returned to activity at a mean 1.4 months (interquartile range (IQR) 0.7 to 2.1) while PDED patients returned at a mean 2.4 months (IQR 1.7 to 3) (p < 0.001). Conclusion Effectiveness in achieving expected correction, LOS and operative time are similar between screw and drill/curettage epiphysiodesis. Patients undergoing PETS demonstrated a faster return to baseline activity than patients with PDED. Level of Evidence III

Purpose Treatment of idiopathic clubfoot with the Ponseti method is now standard, but predicting relapse can be difficult. Most experts recommend bracing to the age of four years, but this can be challenging for families, and may not be necessary in all patients. The purpose of this study is to compare patterns of bracing and age of relapse to help determine if predictable patterns exist. Methods The 70 patients with idiopathic clubfoot treated initially with the Ponseti technique who had relapse of their clubfoot were identified. Relapse was defined as a return to casting or surgery due to recurrent deformity. Data collected included demographics, treatment and brace adherence. Patients who sustained initial relapse before the age of two years were compared with those who sustained initial relapse after the age of two years. Results In total 56% (39/70) had their initial relapse prior to age two years while 44% (31/70) were after age two years. Of the patients who relapsed prior to the age of two years, 28% (11/39) were adherent with bracing while 72% were non-adherent. For patients who initially relapsed after age two, 74% (23/31) were adherent with bracing while 26% were non-adherent (p < 0.001). Of those who had initial relapse prior to age two, a subsequent relapse was seen in 69% (27/39). Conclusion Patients with idiopathic clubfoot who experienced recurrence prior to age two years are significantly more likely to be non-adherent with bracing than those who sustain recurrence after age two. After initial relapse prior to age two, bracing adherence does not affect likelihood of subsequent recurrence.

Posteromedial subtalar (PMST) coalitions are a recently described anatomic subtype of tarsal coalitions. We compared with clinical patient-based outcomes of patients with PMST and standard middle facet (MF) coalitions who had undergone surgical excision of their coalition. The included patients had undergone surgical excision of a subtalar tarsal coalition, preoperative computed tomography (CT), and patient-based outcomes measures after surgery (including the American Orthopaedic Foot and Ankle Society [AOFAS] scale and University of California, Los Angeles [UCLA], activity score). Blinded analysis of the preoperative CT scan findings determined the presence of a standard MF versus a PMST coalition. The perioperative factors and postoperative outcomes between the MF and PMST coalitions were compared. A total of 51 feet (36 patients) were included. The mean follow-up duration was 2.6 years after surgery. Of the 51 feet, 15 (29.4%) had a PMST coalition and 36 (70.6%) had an MF coalition. No difference was found in the UCLA activity score; however, the mean AOFAS scale score was higher for patients with PMST (95.7) than for those with MF (86.5; p = .018). Of the patients with a PMST, none had foot pain limiting their activities at the final clinical follow-up visit. However, in the group with an MF subtalar coalition, 10 (27.8%) had ongoing foot pain limiting activity at the final follow-up visit (p = .024). Compared with MF subtalar tarsal coalitions, patients with PMST coalitions showed significantly improved clinical outcomes after excision. Preoperative identification of the facet morphology can improve patient counseling and expectations after surgery.

In this descriptive analysis of pediatric Lisfranc injuries, records of 56 children treated for bony or ligamentous Lisfranc injuries over a 12-year period were reviewed. Overall, 51% of fractures and 82% of sprains were sports-related (P=0.03). A total of 34% of the cohort underwent open reduction internal fixation, which was more common among patients with closed physes (67%). Full weight bearing was allowed in open reduction internal fixation patients at a mean of 14.5 weeks, compared to 6.5 weeks in the nonoperative group. Complications were rare (4%) and included physeal arrest in one patient and a broken, retained implant in one patient.

Standardized clinical assessment and management plans (SCAMPs) are a novel quality improvement initiative shown to improve patient care, diminish practice variation, and reduce resource utilization. Unlike clinical practice guidelines, a SCAMP is a flexible algorithm that undergoes iterative updates based on periodic data collection and review. We recently implemented a SCAMP for the closed treatment of pediatric torus fractures. The purpose of this study is to analyze the effect of SCAMP implementation on resource utilization, practice variability, cost of care, and outcomes.This study was a retrospective review of prospectively collected data on 273 patients with pediatric torus fractures. The pre-SCAMP cohort included 116 subjects from 2008 to 2010. The SCAMP cohort included 157 subjects from 2011 to 2013. The pre-SCAMP cohort was treated according to the judgment of attending fellowship-trained pediatric orthopaedic surgeons. The SCAMP cohort was treated with a standardized algorithm including radiographs and splint application at initial presentation, with a single follow-up at 3 weeks. Patient demographics were analyzed to verify comparability between cohorts. Follow-up data including clinic visits, x-rays and practice variability was recorded. Costing analysis was conducted using time-derived activity-based costing methodology. Outcomes were compared using Poisson regression analysis. Incident rate ratios (IRR) with 95% confidence limits were estimated.No differences in clinical results were observed between the pre-SCAMP and SCAMP cohorts, and all patients demonstrated return to baseline activity at final follow-up. Patient demographics were comparable across cohorts. The SCAMP cohort had a 48% reduction in clinic visits [IRR, 0.52; 95% confidence interval (CI), 0.44-0.60; P0.001], 60% reduction in x-rays (IRR, 0.40; CI, 0.33-0.47; P0.001), and a 23% reduction in x-rays per clinic visit (IRR, 0.77; 95% CI, 0.65-0.91; P0.001). Furthermore, SCAMP implementation resulted in a 49% reduction in the overall cost of care.SCAMPs provide a novel alternative to CPGs to implement cost effective changes in Orthopaedic practice. For pediatric torus fractures, SCAMP implementation resulted in decreased practice variability, resource utilization, and overall cost of care while maintaining clinical outcomes.Level 3.

OBJECTIVES: Pediatric pain management has rapidly changed over the last 2 decades. In this study, we describe the changing practices and adverse events (AEs) related to patient-controlled analgesia (PCA) and/or nurse-controlled analgesia (NCA) over a 22-year period. METHODS: After institutional review board approval, retrospective data from a single tertiary-care pediatric hospital were collected between 1994 and 2016. Subgroup analyses were done for surgical and medical case patients. We reported the number of times that PCA and/or NCA was ordered annually, the median and interquartile ranges for age, PCA and/or NCA duration and length of stay, and AE frequencies. RESULTS: Over 22 years, 32 338 PCAs and/or NCAs were ordered in this institution. Morphine and hydromorphone were used most commonly. Between 1994 and 2006, initial orders for PCA and/or NCA increased 2.5-fold. After 2007, initial orders for PCA and/or NCA rapidly decreased; after 2013, the decrease continued at a slower rate, with a total of 1007 orders in 2016. This decrease occurred despite increased hospital admissions and surgeries. Between 2007 and 2012, peripheral nerve blocks rapidly increased (10-fold). After 2002, 146 AEs were reported (1.0%). Of those, 50.5% were nonintercepted, and 20.6% were intercepted AEs; 5.5% and 6.2% were preventable and nonpreventable AEs, respectively. CONCLUSIONS: PCA and/or NCA usage continues to be common in pediatric patients, although usage has declined and stabilized in the setting of other emerging methods of analgesia and increases in the number of minimally invasive surgical procedures. The overall rate of AEs was extremely low. However, improvements to eliminate all errors are needed, especially with medications with a great risk of harm (such as opioids).

Background:Operative treatment of juvenile hallux valgus (JHV) has a high recurrence rate. The aim of this study was to better understand the pattern of radiographic deformity.Methods:Standing radiographs of 93 feet in 57 patients with JHV, and 50 feet in 36 normal patients were measured. Measurements included: hallux valgus angle (HVA), first metatarsal physis status (open or closed), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), Meary’s angle, medial cuneiform angle (MCA), relative first to second metatarsal length ratio (1:2 MT ratio), cuneiform obliquity (CO), and congruency of the metatarsophalangeal joint (MTPJ). JHV groups were defined as normal (HVA 0-15 degrees), mild-moderate (HVA 15-35), or severe (HVA > 35) and were analyzed.Results:Seventy of 93 feet (75%) with JHV presented with mild-moderate JHV (average HVA of 26.2 ± 5.6 degrees), and 23 feet (25%, 23/93) presented with severe JHV (average HVA of 41.9 ± 5.3 degrees). Multivariable analysis determined that DMAA ( P < .001), MCA ( P = .04), and congruency ( P < .001) were independently associated with JHV and its severity (normal vs mild-moderate vs severe). Severe JHV cases had larger DMAA ( P = .01), larger IMA ( P = .01), larger 1:2 MT ratio ( P = .02), and were less frequently congruent ( P = .03) compared with mild-moderate JHV cases.Conclusion:Deformity in JHV was highly correlated with both the proximal and distal morphology of the first metatarsal and medial cuneiform. Severe JHV was associated with increased bony deformity and increased incongruity of the MTPJ. Treatment should be individualized, but JHV treatment algorithms can take this information into account.Level of Evidence:Level III, comparative study.

BACKGROUND Fractures of the fifth metatarsal bone are common and surgery is uncommon. The "Jones" fracture is known to be in a watershed region that often leads to compromised healing, however, a "true Jones" fracture can be difficult to determine, and its impact on healing in pediatric patients is not well described. The purpose of this study was to retrospectively assess patterns of fifth metatarsal fracture that led to surgical fixation in an attempt to predict the likelihood for surgery in these injuries. METHODS A retrospective review was performed on patients aged 18 and under who were treated for an isolated fifth metatarsal fracture from 2003 through 2010 at our pediatric hospital. Patient demographics, treatment, and complications were noted. Radiographs were reviewed for location of fracture and fracture displacement. Patients and fracture characteristics were then compared. RESULTS A total of 238 fractures were included and 15 were treated surgically. Most surgical indications were failure to heal in a timely manner or refracture and all patients underwent a trial of nonoperative treatment. Jones criteria for fracture location were predictive of needing surgery (P

Background Noise reduction headphones decrease the sound during cast removal. Their effectiveness in decreasing anxiety has not been studied. Purpose Compare pediatric patients' anxiety levels during cast removal with and without utilization of noise reduction headphones combined with use of a personal electronic device. Methods Quality improvement project. Patients randomly assigned to noise reduction headphone group or standard care group during cast removal. Faces, Legs, Activity, Cry, and Consolability Scale and heart rate were evaluated prior to, during, and after cast removal. Data were compared across groups. Results Fifty patients were included; 25 per group. No difference detected between the 2 groups in Faces, Legs, Activity, Cry, and Consolability Scale score prior to (p = .05) or after cast removal (p = .30). During cast removal, the headphone group had lower FLACC Scale scores (p = .03). Baseline heart rate was lower in the headphone group prior to (p = .02) and after (p = .005) cast removal with no difference during cast removal (p = .24). Conclusion Utilizing noise reduction headphones and a personal electronic device during the cast removal process decreases patient anxiety.

Background Clubfoot is associated with maternal cigarette smoking in several studies, but it is not clear if this association is confined to women who smoke throughout the at-risk period. Maternal alcohol and coffee drinking have not been well studied in relation to clubfoot. Methods The present study used data from a population-based case–control study of clubfoot conducted in Massachusetts, New York, and North Carolina from 2007 to 2011. Mothers of 646 isolated clubfoot cases and 2037 controls were interviewed about pregnancy events and exposures, including the timing and frequency of cigarette smoking, alcohol intake, and coffee drinking. Results More mothers of cases than controls reported smoking during early pregnancy (28.9% vs. 19.1%). Of women who smoked when they became pregnant, those who quit in the month after a first missed period had a 40% increase in clubfoot risk and those who continued to smoke during the next 3 months had more than a doubling in risk, after controlling for demographic factors, parity, obesity, and specific medication exposures. Adjusted odds ratios for women who drank >3 servings of alcohol or coffee per day throughout early pregnancy were 2.38 and 1.77, respectively, but the numbers of exposed women were small and odds ratios were unstable. Conclusions Clubfoot risk appears to be increased for offspring of women who smoke cigarettes, particularly those who continue smoking after pregnancy is recognisable, regardless of amount. For alcohol and coffee drinkers, suggested increased risks were only observed in higher levels of intake.

Clubfoot, a common major structural malformation, develops early in gestation. Epidemiologic studies have identified higher risks among boys, first-born children, and babies with a family history of clubfoot, but studies of risks associated with maternal exposures are lacking. We conducted the first large-scale, population-based, case-control study of clubfoot with detailed information on maternal medication use in pregnancy. Study subjects were ascertained from birth defect registries in Massachusetts, New York, and North Carolina during 2007-2011. Cases were 646 mothers of children with clubfoot without other major structural malformations (i.e., isolated clubfoot); controls were mothers of 2,037 children born without major malformations. Mothers were interviewed within 12 months of delivery about medication use, including product, timing, and frequency. Odds ratios were estimated for exposure to 27 medications in pregnancy months 2-4 after adjustment for study site, infant sex, first-born status, body mass index (weight (kg)/height (m)(2)), and smoking. Odds ratios were less than 1.20 for 14 of the medications; of the remainder, most odds ratios were only slightly elevated (range, 1.21-1.66), with wide confidence intervals. The use of antiviral drugs was more common in clubfoot cases than in controls (odds ratio = 4.22, 95% confidence interval: 1.52, 11.73). Most of these results are new findings and require confirmation in other studies.

Intra-articular fractures of the proximal phalanx of the great toe in children are extremely rare and sparsely reported in the literature. We have noted a series of these fractures at our institution. The purpose of this report is to present a retrospective case series of children with intra-articular fractures managed operatively in order to highlight the inherent difficulties in managing these fractures.Operative notes and billing records were searched from 2001 to 2011 to identify all children aged 18 years or younger who underwent surgical intervention for an intra-articular fracture of the proximal phalanx of the great toe. Charts and imaging studies were retrospectively reviewed to identify the mechanism of injury, fracture classification, operative details, clinical results, and complications.Seven boys and 3 girls with a mean age of 12.6 years (range, 8.7 to 15.7 y) were identified. The mechanism of injury was a direct blow from a stubbed toe (8 cases) or a dropped object onto the foot (2 cases). There were 7 intra-articular fractures of the proximal phalanx base, 4 of which occurred in the setting of an open physis. Mean fracture displacement was 4.4 mm. Open reduction was necessary in 9 cases, with K-wire fixation used in 9 cases. Median follow-up was 50.5 months (range, 11 to 123 mo). Seven fractures healed at a mean of 7.9 weeks. Nine patients returned to full activity without limitation at latest follow-up. Six patients had significant complications: 2 underwent revision open reduction internal fixation (one for postoperative redisplacement and the other for painful nonunion), 1 suffered a refracture, 1 developed posttraumatic arthritis requiring interphalangeal joint fusion, 1 developed an asymptomatic fibrous nonunion with avascular necrosis of the fragment, and 1 had K-wire migration necessitating early surgical removal.Intra-articular fractures of the great toe primarily occur in adolescents after direct impact injuries. The most common location was the proximal phalangeal base. There is a high complication rate after surgical intervention, although most patients were asymptomatic at latest follow-up.IV (retrospective case series).

Objectives: Orthopaedists often speculate how weather and school schedule may influence pediatric orthopedic trauma volume, but few studies have examined this. This study aims to determine: how do weather patterns, day, month, season and public school schedule influence the daily frequency of pediatric orthopedic trauma consults and admissions? Methods: With IRB approval, orthopedic trauma data from a level 1 pediatric trauma center, including number of daily orthopedic trauma consults and admissions, were collected from July 2009 to March 2012. Historical weather data (high temperatures, precipitation and hours of daylight), along with local public school schedule data were collected for the same time period. Univariate and multivariate regression models were used to show the average number of orthopedic trauma consults and admissions as a function of weather and temporal variables. Results: High temperature, precipitation, month and day of the week significantly affected the number of daily consults and admissions. The number of consults and admissions increased by 1% for each degree increase in temperature (p=0.001 and p Conclusion: Pediatric orthopedic trauma consultations and admissions are highly linked to temperature and precipitation, as well as day of the week and time of year.

UNLABELLED Fractures of multiple metatarsals in the pediatric population are uncommon; however, indications for surgical treatment have not been delineated. The aim of this study was to review multiple metatarsal fractures to help refine surgical indications. A total of 98 patients had multiple metatarsal fractures; displacement greater than 10% shaft width (displaced) was encountered in 33 (34.0%) patients. Fifteen patients had displacement of more than 75% shaft width of one metatarsal. Patients older than 14 years of age were more likely to have surgery for their injury (52.6%) than those younger than 14 years of age (3.7%) (P

Charcot-Marie-Tooth (CMT) disease is an inherited progressive neurologic disorder often diagnosed by the characteristic cavovarus feet. In the pediatric population, the presentation is often more variable and age dependent. Pediatric orthopedic surgeons may be referred patients for the evaluation of musculoskeletal symptoms that may be consistent with early CMT, but because of the lack of the surgeon's familiarity, the diagnosis may be delayed or missed. We present three patients with pes planovalgus who were found to have CMT and review the recent literature relevant to the pediatric orthopedic surgeon. The clinical summary is given for three patients who presented to the orthopedic surgery department for lower extremity symptoms and were eventually diagnosed with CMT. A literature search was performed and information valuable for a pediatric orthopedic surgeon to consider is summarized. Foot morphology in most young children with CMT initially is pes planovalgus, with the minority being pes cavovarus. As the child grows, the proportion changes to become nearly entirely cavus or cavovarus, with very few remaining planovalgus or planus. Unexplained regional pain may also be suggestive of CMT. Whereas CMT often presents initially in adolescent or adult patients with cavovarus feet, thin calves, or a high-stepping gait, pediatric presentation is not so consistent. Young children with CMT often have pes planovalgus. There are even some variants of CMT where patients still may present with severe pes planovalgus into late adolescence. We recommend that pediatric orthopedic surgeons consider CMT even in patients who do not have cavus or cavovarus feet, especially in the context of unexplained regional pain of the lower extremities. Patients should be referred to a pediatric neurologist for definitive diagnosis and management, with the orthopedic surgeon remaining involved for specific procedures.

Spine fractures are rare in the pediatric population. Children have different injury patterns compared with adults secondary to distinct anatomic and biomechanical features in the immature spine. Upper cervical spine injuries are more common in children 8 years or less and lower cervical spine injuries are more common in children over 8 years. Young children have a disproportionately large head and should be transported on a specialized backboard to prevent excessive neck flexion. Initial assessment consists of a thorough history, physical examination and plain radiographs. Normal radiographic variants in the pediatric spine can mimic injury and understanding of these parameters is critical. Unique pediatric injuries include fractures through the synchondrosis, apophyseal injuries and spinal cord injury without radiographic abnormality. Computed tomography or magnetic resonance imaging may be helpful to further evaluate these injuries. Treatment consists of immobilization in an appropriate orthosis or surgical stabilization. A high index of suspicion and systematic evaluation and treatment of pediatric spine injuries can limit morbidity and lead to an improved outcome.

Background Pediatric talus fractures are rare with variable rates of posttraumatic complications reported in the literature. The purpose of this retrospective study was to evaluate posttraumatic complications in children after talus fracture and report injury characteristics. Methods This study included 29 children with talus fractures sustained between 1999 and 2008 at an average age of 13.5 years (range, 1.2-17.8). Patient records and radiographs were reviewed to determine the mechanism of injury, fracture type, associated injuries, and treatment. Posttraumatic complications assessed were avascular necrosis, arthrosis, nonunion or delayed union, neurapraxia, infection or wound-healing problems, and the need for further unanticipated surgery. Clinical follow-up averaged 24 months (range, 6 mo-5 y). Results Twenty-nine children sustained a major fracture of the talar body, neck, or head. Avascular necrosis occurred in 2 patients (7%), arthrosis in 5 (17%), delayed union in 1 (3%), neurapraxia in 2 (7%), infection in 0, and the need for further surgery in 3 (10%). Both high-energy mechanism and fracture displacement corresponded to a greater number of posttraumatic complications. The number and severity of talus fractures increased in older children. Conclusions In this case series, posttraumatic complications after pediatric talus fractures occurred more frequently after a high-energy mechanism of injury or a displaced fracture. Talus fractures occurred more commonly and with more severity in older children. Level of evidence Level IV. Retrospective case series.

Background: Use of ultrasound in the prenatal period is increasing and musculoskeletal anomalies are often found. Parents-to-be are often confronted with the reality of a potentially imperfect child part-way into the pregnancy. Prenatal counseling with a pediatric orthopaedic surgeon may be of some benefit to alleviate concerns. Methods: Musculoskeletal anomalies found on prenatal ultrasound are reviewed, including those in the upper extremeity, spine, syndromes, and lower extremity. Incidence and associated anomalies are discussed. Results: Many different musculoskeletal anomalies across a broad spectrum of potential severity may be found on prenatal ultrasound. In most cases, isolated musculoskeletal diagnoses have the potential for excellent long-term function. Prenatal counseling with the parents-to-be may properly inform them of the issues and treatment expectations for their unborn child, and relieve their concerns and fears. Conclusions: Prenatal counseling with a pediatric orthopaedic surgeon for musculoskeletal diagnoses found on ultrasound may alleviate fears of the parents and better inform them of the treatment expectations for their unborn child.

Children with pelvic osteomyelitis may present with symptoms that are nonspecific. Conventional imaging modalities including plain radiographs, ultrasound, technetium bone scan, and computed tomography rarely demonstrate pathology that is diagnostic of this condition. As a result, accurate diagnosis is often delayed, and children may undergo surgical diagnostic or therapeutic procedures that may be avoided. We report the radiographic and magnetic resonance imaging (MRI) findings in 23 children admitted with a suspected diagnosis of pelvic osteomyelitis. We are presenting imaging findings in children with suspected pelvic osteomyelitis with emphasis on MRI abnormalities and to propose an anatomical classification based on the patterns of pelvic involvement.The medical records and imaging reports of all patients admitted to our institution with a history and physical examination suggestive of pelvic osteomyelitis between July 31, 1992, and March 10, 2003 were reviewed. Criteria were defined for the diagnosis of pelvic osteomyelitis based on criteria used by Farley et al in 1985. Specific attention was paid to the imaging strategies used and the influence of each radiographic method on the ultimate diagnosis.Abnormalities on the MRI included soft tissue inflammation and bone edema. These findings were bright on T2 and short inversion time Short T1 inversion recovery (STIR) images and enhanced after gadolinium administration. Five distinct patterns of pelvic involvement were observed, each corresponding to a cartilaginous epiphysis or apophysis. These were the sacroiliac joint, triradiate cartilage, pubic symphysis, ischium, and iliac apophysis. One patient had a noninfectious cause of presentation with a deep vein thrombosis, whereas another was diagnosed with Hodgkin lymphoma in addition to osteomyelitis of the ischium.Magnetic resonance imaging is a sensitive technique for evaluation of pyogenic infections involving the pelvis. In patients presenting with clinical findings and laboratory studies suggesting an infectious process, MRI with gadolinium enhancement should be performed as an early study. Magnetic resonance imaging is also effective in identifying other conditions that may resemble pelvic osteomyelitis.

Cast immobilization remains the mainstay of pediatric orthopaedic care, yet little is known about the incidence of cast-related skin complications in children treated with cast immobilization. The purposes of this quality improvement project were to: (1) establish a baseline rate of cast-related skin complications in children treated with cast immobilization, (2) identify trends in children who experienced cast-related skin complications, (3) design an intervention aimed at decreasing the rate of cast-related skin complications, and (4) determine the effectiveness of the intervention. A prospective interrupted time-series design was used to determine the incidence of cast-related skin complications overtime and compare the rates of skin complications before and after an intervention designed to decrease the incidence of cast-related heel complications. All consecutive patients who were treated with cast immobilization from September 2012 to September 2014 were included. A cast-related skin complications data collection tool was used to capture all cast-related skin complications. A high rate of heel events was noted in our preliminary analysis and an intervention was designed to decrease the rate of cast-related skin complications, including the addition of padding during casting and respective provider education. The estimated cast-related skin events rate for all patients was 8.9 per 1000 casts applied. The rate for the total preintervention sample was 13.6 per 1000 casts which decreased to 6.6 in the postintervention sample. When examining the heel-only group, the rate was 17.1 per 1000 lower extremity casts applied in the preintervention group and 6.8 in the postintervention group. Incorporating padding to the heel of lower extremity cast was an effective intervention in decreasing the incidence of cast-related skin complications in patients treated with cast immobilization.

A variant form of subtalar coalition isolated to the posterior sustentaculum has been previously described, though its prevalence is not known and its relationship to the middle facet has not been characterized. To determine the prevalence and morphological alterations of isolated posteromedial subtalar coalitions. Computed tomography (CT) images of the foot or ankle performed from 2004 to 2012 were reviewed and 97 patients (mean age: 13.3+/-2.9 years; range: 9-19 years) with subtalar coalition were identified. In 41 (42%) of these, the condition was bilateral, yielding a total of 138 subtalar coalitions. In the 33 patients where CT demonstrated isolated posteromedial subtalar coalitions, multiplanar reformats along the long axis of the sustentaculum tali were generated, from which the anteroposterior dimensions of the sustentaculum tali and middle facet were measured. Posterior sustentaculum measurements defining the posterior extension of the sustentaculum beyond the middle facet were directly measured by two radiologists. Ratios of middle facet to posterior sustentaculum measurements were calculated. Thirty-three patients undergoing CT for ankle fracture served as controls. Ninety-seven of 138 coalitions (70.2%) affected the middle facet and 2/138 (1.4%) involved the posterior facet. There were 39 (28.2%) posteromedial subtalar coalitions in 33 patients. Mean AP measurements of the middle facet and posterior sustentaculum in patients with posteromedial subtalar coalitions were 12.6 mm and 18.2 mm, respectively, compared to 16.6 mm and 9.2 mm in controls (P

There are little patient-reported data on functional outcomes of tarsal coalition resection in children and adolescents. The purpose of this study is to evaluate the medium-term (2 y) outcomes in patients who have had surgical excision of their symptomatic tarsal coalition and to compare patient-based outcomes in patients who have calcaneonavicular (CN) coalitions to those with talocalcaneal (TC) coalitions.A billing query was conducted to identify patients who had surgical excision of their tarsal coalition between 2003 and 2008. Eligible patients were mailed questionnaires consisting of a modified American Orthopaedic Foot and Ankle Society (AOFAS) score and the University of California at Los Angeles (UCLA) activity scale. Patients were also specifically asked if their activity level was limited by their foot pain. Only patients who returned questionnaires were included. Demographics and diagnostic images were reviewed. A nonresponder analysis was completed. Complications such as infection and reoperation were reported.Sixty-three patients (22 females, 41 males) who returned questionnaires were included in the analysis. Twenty-four patients had bilateral surgery. TC coalitions were present in 20 patients (32%); CN coalitions were present in 43 patients (68%).Overall, mean modified AOFAS score was 88.3 and mean UCLA activity score was 8.33 at an average of 4.62 years after surgery. Patients who had TC coalitions had similar modified AOFAS scores (88.4) and UCLA activity scores (8.4) when compared with those with CN coalitions (88.0 and 8.3, both not significant).Of the 73% (46/63) patients who reported that their activity levels were not limited by their foot pain, the mean AOFAS score was 93.9 and the mean UCLA activity score was 8.9; 32 of these were CN and 14 were TC coalitions. Of the 27% (17/63) patients who reported that their activity levels were limited by their foot pain, the mean AOFAS score was 72.9 and the mean UCLA activity score was 6.9; 11 of these were CN and 6 were TC coalitions. There was a statistically significant difference in these groups both in modified AOFAS score (P0.0001) and UCLA activity score (P=0.006). There was no difference in outcomes between those who were treated for a TC and CN coalition.Patient-reported outcomes after surgical excision of tarsal coalition reveal that70% of patients' activities are not limited by pain and their functional outcome is terrific. A few patients continue to have problems with ongoing foot pain and activity limitations. The type of coalition does not seem to be an indicative factor in determining outcome.

Quality-of-life (QOL) measures can be a valuable tool to assess the general welfare across a spectrum of patients in a pediatric orthopaedic outpatient clinic and can be a simple way to assess patient-based outcomes particularly for quality initiatives. The Pediatric Outcomes Data Collection Instrument (PODCI) is validated for many orthopaedic conditions but typically takes around 20 minutes to complete (86 questions). The Pediatric Quality of Life Inventory (PedsQL) takes4 minutes to complete (23 questions) but has not been assessed in an orthopaedic setting. We initiated this study to find the best method for assessing QOL in our outpatient clinic. A short pediatric QOL measure that is correlated to an established orthopaedic-specific QOL measure is needed; therefore, we compared the PedsQL to the PODCI in the outpatient orthopaedic clinic.This was a quality initiative project and as such did not require a priori IRB approval. Families of patients 2 to 18 years old who presented for follow-up after upper or lower extremity fractures or brachial plexus injuries in the orthopaedic clinic from October 2010 through August 2011 were asked to fill out both the PODCI and the PedsQL. Patients aged 5 years and older filled out a patient-report PedsQL; patients aged 11 years and older filled out the patient-report PODCI. Parents/guardians completed questionnaires for children of all ages. Most fracture patients (and/or their parent/guardian) repeated the questionnaires after 6 to 12 weeks. Data were then assessed for correlation between the PODCI and PedsQL.A total of 428 parent/guardian reports for 283 patients and 172 self-reports for 104 patients were included. The correlation between the PODCI Global score and the PedsQL Total score for the parent/guardian-reported questionnaires for all injuries was 0.77 (95% confidence interval, 0.72-0.82). When categorized within domains and injuries, parent/guardian-reported correlations ranged from 0.23 to 0.79. In patients aged 11 years and older, the correlation between the PODCI and PedsQL for the patient-reported questionnaire for all injuries was 0.85 (95% confidence interval, 0.80-0.89). When categorized within domains and injuries, patient-reported correlations ranged from 0.30 to 0.99.Utilizing the substantially shorter PedsQL in a high volume orthopaedic clinic as a substitute for the PODCI for quality improvement measures seems reasonable. Correlation between the PedsQL Global score and the PODCI Total score for orthopaedic patients is strong. Utilizing the patient-reported questionnaires when age appropriate is best. In this era of increased outcome reporting, PedsQL may be a valuable tool.

INTRODUCTION Treatment of idiopathic clubfoot has shifted towards Ponseti technique, but previously surgical management was standard. Outcomes of surgery have varied, with many authors reporting discouraging results. Our purpose was to evaluate a single surgeon's series of children with idiopathic clubfoot treated with a la carte posteromedial and lateral releases using the Pediatric Outcomes Data Collection Instrument (PODCI) with a minimum of 2-year follow-up. METHODS A total of 148 patients with idiopathic clubfoot treated surgically by a single surgeon over 15 years were identified, and mailed PODCI questionnaires. Fifty percent of the patients were located and responded, resulting in 74 complete questionnaires. Median age at surgery was 10 months (range, 5.3 to 84.7 mo), male sex 53/74 (71.6%), bilateral surgery 31/74 (41.9%), and average follow-up of 9.7 years. PODCI responses were compared with previously published normal healthy controls using t test for each separate category. Included in the methods is the individual surgeon's operative technique. RESULTS In PODCIs where a parent reports for their child or adolescent, there was no difference between our data and the healthy controls in any of the 5 categories. In PODCI where an adolescent self-reports, there was no difference in 4 of 5 categories; significant difference was only found between our data (mean = 95.2; SD = 7.427) and normal controls (mean = 86.3; SD = 12.5) in Happiness Scale (P = 0.0031). DISCUSSION In this group of idiopathic clubfoot patients, treated with judicious posteromedial release by a single surgeon, primarily when surgery was treatment of choice for clubfoot, patient-based outcomes are not different from their normal healthy peers through childhood and adolescence. While Ponseti treatment has since become the treatment of choice for clubfoot, surgical treatment, in some hands, has led to satisfactory results. LEVEL OF EVIDENCE Level III.

Introduction : Tibia fractures are common in pediatric patients and time necessary to return to normal function may be underappreciated. The purpose of this study was to assess functional recovery in pediatric patients who sustain tibia fractures, utilizing the Pediatrics Outcome Data Collection Instrument (PODCI), in order to provide evidence-based information on post-injury functional limitations and anticipated recovery times. Methods : 84patients (out of 264 eligible patients, response rate 32%) age 1.5-18 years treated for a tibia fracture at a large children's hospital between 1/07 and 4/08 completed a PODCI questionnaire at 6 and 12 months post-injury. PODCI questionnaires were compared to previously reportednormal controls using Student's t-test in six categories. Results : At 6 months after injury, the Sports functioning PODCI score was significantly less than healthy controls in both the parent reports for adolescent (mean 88.71 versus 95.4) and adolescent self-report (mean 90.44 versus 97.1); these showed no difference at 12 months. Discussion : For adolescents who sustain fractures of the tibia, there remains a negative impact on their sports functioning after 6 months that resolves by 12 months. Physicians can counsel their patients that although they may be limited in their sports function for some time after injury, it is anticipated that this will resolve by one year from the time of injury.

Patients with idiopathic clubfoot are considered at increased risk for having developmental dysplasia of the hips (DDH). However, the studies showing this association have been relatively small. Many clinicians who treat idiopathic clubfoot routinely screen the hips of these patients with ultrasound or radiograph due to the concerns of increased risk of DDH. We evaluated a large clubfoot population to determine the risk of DDH and compare this to a population of children without clubfoot. We also evaluated if the clubfoot patients found to have DDH would have been discovered by standard DDH screening.We identified infants in 3 states (MA, NY, NC), who were reported to each state's birth defects registry as having a clubfoot. A second cohort of infants without clubfoot was also identified as a control group. Mothers of these children were contacted to be included in the study, and a computer-assisted telephone interview was administered by one of the study nurses, including questions about treatment of DDH. The child's median age at interview was 7 months. Mothers of clubfoot cases were also contacted for follow-up at mean age of 3.3 years.Families of 677 patients with clubfoot and 2037 controls were interviewed. A total of 5/677 (0.74%) patients with clubfoot and 5/2037 (0.25%) controls reported having their infant treated with a brace or harness for hip problems (P=0.134). Of the patients with clubfoot, 2 of them did not need treatment for their DDH and 2 would have been discovered by standard hip screening. Follow-up study at 3.3 years of age found no serious late hip dysplasia.Treatment of DDH was uncommon in all children; the higher proportion in infants with clubfoot was not statistically different than controls. Of the patients with clubfoot and DDH, standard hip screening would have been appropriate and others did not need treatment. These data suggest that routine hip ultrasound or radiographic screening of idiopathic clubfoot patients is not necessary unless indicated by the standard infant hip screening.Level 3 study.

Clubfoot is a common structural malformation, occurring in approximately 1/1,000 live births. Previous studies of sociodemographic and pregnancy-related risk factors have been inconsistent, with the exception of the strong male preponderance and association with primiparity. Hypotheses for clubfoot pathogenesis include fetal constraint, Mendelian-inheritance, and vascular disruption, but its etiology remains elusive. We conducted a population-based case-control study of clubfoot in North Carolina, Massachusetts, and New York from 2007 to 2011. Mothers of 677 clubfoot cases and 2,037 non-malformed controls were interviewed within 1 year of delivery about socio-demographic and reproductive factors. Cases and controls were compared for child's sex, maternal age, education, cohabitation status, race/ethnicity, state, gravidity, parity, body mass index (BMI), and these pregnancy-related conditions: oligohydramnios, breech delivery, bicornuate uterus, plural birth, early amniocentesis (

We present a simple and reliable method to calibrate respiratory magnetometers and Respitrace to infer respiratory volume changes. As in earlier methods, we assume two degrees of freedom in the chest wall and that volume displacement depends linearly on surface motion at the rib cage and abdomen. Because the area of the rib cage is larger, a given motion of its surface produces a greater lung volume change; therefore, the rib cage motion signal is given a larger gain before the two signals are added to estimate volume. In contrast to earlier methods, we use a “standard ratio” to weight relative gains of the rib cage and abdominal signals for all subjects rather than determining a gain ratio for each individual subject. Our procedure does not require subjects to perform the sometimes difficult isovolume maneuvers used in the calibration method of Konno and Mead (J. Appl. Physiol. 22: 407–422, 1967), does not require statistical computation used in the multiple-breath linear regression method, and does not produce the occasional substantial errors in gain ratio that may occur with the other methods. When magnetometers are used, the standard ratio is 4:1 (rib cage-to-abdomen); when Respitrace is used, the standard ratio is 2:1. In 11 subjects, calibration with standard ratios was as accurate as the isovolume and linear regression techniques. Accuracy during normal breathing was nearly always within 10% (median 2%), but occasional large errors occurred with both instruments.

Background: The purpose of this study was to prospectively evaluate our recently described fetal sonographic classification system for prenatal diagnosis of clubfoot. Methods: Over 18 months, we prospectively enrolled consecutive pregnant patients evaluated for a prenatally diagnosed clubfoot. Prenatal sonographic scores assigned by a radiologist were compared to final clinical diagnosis and severity given by a pediatric orthopedic surgeon. Pearson's χ2 test and logistic regression were used in statistical analyses on the subject level. Generalized estimating equations were used in analyses on the foot level to account for intrasubject correlation. Results: There were 50 subjects, with 26 unilateral and 24 bilateral clubfeet, according to the prenatal ultrasound (US). A total of 51 (69%) of 74 feet and 36 (72%) of 50 subjects had a postnatal diagnosis of clubfoot. The accuracy of diagnosis in cases of a severe, moderate, and mild US score was 94, 70, and 25%, respectively (p = 0.003 comparing moderate-severe vs. mild). US severity correlated with the Dimeglio classification scoring system (Spearman's correlation 0.30). Conclusion: The fetal sonographic scoring system is predictive of clinical severity after birth, and improves the ability to counsel families with a prenatal diagnosis of clubfoot.

BACKGROUND A recent prospective randomized clinical trial (RCT) for comparison of medial and lateral entry pins with lateral entry pins for treatment of Gartland type 3 supracondylar humerus fractures (SCHF) was published, validating the national trend toward treatment of this injury with only lateral entry pins. But have surgeons actually changed their practice as a result of these recent data? The purpose of this study was to compare pin configuration, loss of reduction and rate of nerve injuries before and after the RCT. METHODS This was a retrospective review of patients with Gartland type 3 SCHF who were treated before the RCT (April 2000 to April 2003: 141 patients) and after the trial (April 2006 to April 2009: 126 patients). Eight surgeons were included. Patient demographic data, pin configuration, neurovascular status, and radiographic results were compared. Comparisons between the pretrial cohort and the posttrial cohort as a group as well as for each individual surgeon were performed. Comparisons included the choice of pin configuration, incidence of loss of radiographic reduction, iatrogenic nerve injuries, return to the operating room, and infection before and after the clinical trial. RESULTS There was a statistically different pin configuration in the pretrial group compared with the posttrial group (P
