Background Osseous overgrowth is a common complication in children after humeral transcortical amputation. Capping tibial overgrowth with the proximal fibula has been shown to be the most effective treatment. However, best treatment practices are not clear for the humerus. We compared patients treated surgically for humeral osseous overgrowth with simple resection or autologous osteocartilaginous graft to determine if this treatment were as effective in the humerus as it has been in the tibia. Methods A retrospective review of humeral amputees from 1987 to 2011 at a pediatric hospital was performed. Patients with 2 years follow-up who underwent surgical treatment for established humeral overgrowth were included. Patients initially managed with simple resection were compared with those managed with autologous osteocartilaginous grafts. Descriptive statistics were calculated for demographic and outcome variables. T tests and χ tests were used to compare differences between groups. Results Eighteen humeri in 16 patients met inclusion criteria. Mean age at surgery was 8.3 (2.6 to 13.6) years and mean follow-up was 6.3 (1.5 to 10.4) years. Thirteen humeri underwent simple resection, with recurrent overgrowth in 9, and revision surgery in 8 at a mean 2.6 years. Five humeri were primarily managed with autologous osteocartilaginous grafts. Two developed non-overgrowth-related complications at 1 and 42 months. Including revision procedures after simple resection, 10 humeri were managed with autologous osteocartilaginous grafts. Thirty percent (3/10) required revision surgery; however, there were no cases of recurrent overgrowth. χ comparison showed lower rates of complications (P=0.004) and reoperation (P=0.012) with capping as compared with simple resection. Conclusions Autologous osteocartilaginous capping of the humerus has a significantly lower rate of complications and reoperation compared with simple resection. However, the capping procedure has the potential for other complications related to difficulty with graft fixation. Surgeons should be aware that the outcomes are not as consistent as when the technique is applied to osseous overgrowth of the tibia and anticipate the possibilities of hardware prominence and difficulty with fixation.

OBJECTIVES Randomized trials have shown that removable immobilization devices are at least as good as circumferential casts for the management of common specific types of pediatric wrist and ankle fractures. Our main objective was to determine the proportion of emergency physicians who prescribe removable devices for distal radius buckle fractures and/or nondisplaced distal fibular Salter-Harris I fractures. We also examined follow-up referral patterns for these injuries. METHODS This was an online survey of members of 2 national emergency physician associations in Canada: Pediatric Emergency Research Canada and the Canadian Association of Emergency Physicians. RESULTS Of the 849 eligible participants, 447 responded to the survey, yielding an aggregate response rate of 52.7%. Organization-specific response rates were 169 (70.4%) of 240 for the Pediatric Emergency Research Canada and 278 (45.6%) of 609 for the Canadian Association of Emergency Physicians. Overall, 263 of 416 (63.2%; 95% confidence interval [CI], 58.6-67.8) of emergency physicians treat buckle fractures of the distal radius with a removable splint and refer 212 of 398 (53.3%; 95% CI, 48.4-58.2) of these injuries to the primary care physician for follow-up. For Salter-Harris I fractures of the distal fibula, emergency physicians treat 201 of 416 (48.3%; 95% CI, 43.5-53.1) with a removable ankle support and refer 94 of 398 (23.6%; 95% CI, 19.4-27.8) to the primary care physician for follow-up. CONCLUSIONS At least 50% of the surveyed Canadian emergency physicians treat distal radius buckle fractures and/or Salter-Harris I fibular fractures with a removable immobilization device, and the primary care physician follow-up of these injuries occur with some regularity for both these injuries.

Objective The primary objective of this study was to determine if Gartland type I supracondylar humerus (SCH) fractures undergo significant displacement resulting in a change in management when treated with a long-arm splint. Secondary objectives included measured changes at follow-up in displacement and/or angulation. Methods This was a retrospective review of children who presented with elbow injuries to a children's hospital. Patients were included if they were diagnosed with a Gartland type I SCH fracture, managed with a long-arm splint, and had at least 1 follow-up visit 2 to 3 weeks from the emergency department visit. The primary outcome was the proportion of cases that required the placement of a circumferential cast and/or an operative intervention. Secondary outcomes included the proportion of cases with significant changes in displacement on any view, Baumann or the lateral humerocapitellar angle, and/or category of position of anterior humeral line relative to capitellum. Results Of 804 elbow injuries that presented from 2003 to 2008, 53 patients met the inclusion criteria. The median age of the patients was 4.1 years (interquartile range, 3.4-6.1 years) years. Of the 53, there were no cases that required a change in management. One case had a change in the humerocapitellar angle, and another had a change of 1 category in position of the capitellum relative to the anterior humeral line. There were no other cases of significant changes in displacement or angulation. Conclusions These data support that Gartland type I SCH fractures can be treated effectively with long-arm posterior splinting for the duration of therapy.

Recent studies have questioned the efficacy of releasing hip flexion contractures and the resulting ankle position after tendoachilles lengthening in ambulating children with cerebral palsy (CP).Twenty-three ambulatory children with CP underwent 96 soft tissue-lengthening procedures without bony surgery. Preoperative and postoperative clinical and computerized gait data were reviewed.Static contractures improved reliably, with improvements in all areas measured, including hip flexion contracture (14 degree improvement), hip abduction (19 degree improvement), popliteal angle (26 degree improvement), and ankle dorsiflexion (11 degree improvement). The changes in computerized gait data were less uniform. The knees showed significant benefits, as evidenced by improved maximal knee extension in stance phase (37.3 degree preop and 19.9 degree postop) and at initial contact (51.6 degree preop and 34.8 degree postop). At the hip, a statistically significant improvement was only seen in maximum hip extension in stance phase (minimum hip flexion), and the magnitude of this change was only 4.6 degree (15.3 to 10.7 degree). There were no significant changes at the pelvis. At the ankle, the tendency was toward calcaneal gait after Achilles tendon lengthening, with excessive dorsiflexion seen both in stance (17.3 degree) and at toe off (-6.9 degree). Tempero-spatial parameters showed improved stride length, but no significant changes in gait velocity or cadence.The persistence of crouch postoperatively, though improved, likely limited the potential changes in hip kinematics. As this study excluded patients undergoing osseous surgery, it is possible that lever arm dysfunction may have contributed to the ongoing crouch. The results of this study suggest that static contractures and knee kinematics improve reliably after soft tissue surgery in children with CP, but that caution must be exercised when considering heel cord lengthening in these children.Therapeutic level II.

BACKGROUND Obese patients are highly prevalent in the pediatric orthopaedic surgeon's practice and obesity is an increasing issue in the United States. Increased body mass index (BMI) has been associated with increased complications in pediatric orthopaedic patients, but no study has looked specifically at external fixation. The purpose of this study was to determine whether obesity is a risk factor for increased complications in lower-extremity procedures requiring external fixation. METHODS A retrospective chart review was conducted of pediatric patients who underwent external fixation as definitive operative treatment for any condition at a tertiary care hospital over a 15-year period. Patients were grouped into normal weight, overweight, and obese based on Centers for Disease Control definitions. All orthopaedic complications were recorded. RESULTS A total of 208 patients with a mean age of 11.2 years were identified. Ninety-four children were obese at the 95th percentile BMI or higher, 22 were overweight and 93 were normal weight. External fixation was applied to the tibia in 82 cases, to the femur in 77 and to both in 49. Mean duration of fixation was 160 days (range, 31 to 570 d) and patients were followed for a mean of 3.9 years (range, 1.0 to 12.0 y). There was no statistically significant difference in the rate of complications between the 3 groups (P=0.61). In the obese group complications occurred in 68.1% versus 66.7% in the overweight group and 61.3% in normal weight. CONCLUSIONS In the setting of external fixator use for lower-extremity pathology in pediatric patients, there is no association between an increase in complications and obesity as defined by BMI. Complication rates are high when external fixation is utilized for the lower extremity, however, patients and families should not be counseled that increased BMI will add to the burden of orthopaedic complications in this situation.

Removable splints when compared with circumferential casts in randomized trials have been shown to be a safe and cost-effective method of managing many common minor distal radius and fibular fractures. This study estimated the extent to which this evidence is being implemented in clinical practice, and determined the perceived barriers to the adoption of this evidence.A cross-sectional survey of practicing orthopaedic surgeon members of the Pediatric Orthopedic Surgeons of North America (POSNA) was conducted, using a 22-item online questionnaire, and distributed using a modified Dillman technique. Survey questions were derived from and validated by literature review, expert opinion, and pilot-testing on the targeted sample before implementation.Of the 826 eligible participants, 558 (67.6%) responded to the survey. Of these, 505 (90.5%) had completed a fellowship in pediatric orthopaedics, 335 (60.0%) worked in a university-affiliated setting, and 377 (67.6%) had been in practice for20 years. Only 158/543 [29.1%; 95% confidence interval (CI), 25.28, 32.92] reported using a removable splint to treat buckle fractures of the distal radius; 32 (5.9%; 95% CI, 3.9, 7.9) and 8 (1.5%; 95% CI, 0.5, 2.5) would use such splints for minimally displaced greenstick and transverse fractures of the distal radius, respectively. For distal fibular avulsion fractures, 122 (22.5%; 95% CI, 19.0, 26.0) would use a removable splint; 57 (10.5%; 95% CI, 7.9, 13.1) and 28 (5.6%; 95% CI, 3.7, 7.5) would do so for nondisplaced Salter-Harris I and II fractures of the distal fibula, respectively. The most commonly reported perceived barriers to application of a removable device were concerns about patient compliance, potential complications, and possible medicolegal implications.Only a relatively small proportion of practicing POSNA use such splints for minor distal radius and distal fibular fractures. These data support the need for implementation of knowledge translation strategies (eg, education) targeted at all the stakeholders to encourage pediatric orthopaedic surgeons to change practice in keeping with the best evidence for these common and stable injuries.Level II.

Background: Studies evaluating multilevel surgery to treat spastic deformity and functional deficits in cerebral palsy (CP) usually focus on data from instrumented gait analysis and clinical examination without examining functional and health-related quality of life (HRQOL) outcomes. Recently, outcome measures for well-being in children with a variety of musculoskeletal disorders have also been validated specifically for CP. Therefore, this study aimed to investigate the impact of multilevel surgery on the function and HRQOL in a group of ambulatory children with CP. Methods: In a multicenter prospective trial, 57 ambulatory children with CP, mean age 9.5 years, underwent multilevel soft tissue surgery to correct sagittal imbalance. Validated clinical outcome measures for HRQOL were administered preoperatively and postoperatively with an average follow-up time of 15.2 months. The functional and psychosocial components of the Pediatric Outcomes Data Collection Instrument (PODCI), Pediatric Quality of Life Questionnaire (PedsQL), and the Functional Assessment Questionnaire Walking Score were used. Results: Significant improvements in outcome scores occurred postoperatively in the following: PedsQL parent-total (17.6%; P < 0.001) and parent-physical sections (25.0%; P < 0.001), the Functional Assessment Questionnaire Walking Score (15.3%; P < 0.001), and the PODCI sections for transfers and basic mobility (15.8%; P < 0.001), sports and physical function (23.9%; P = 0.012), and global (12.9%; P < 0.001). Improvements also occurred in the PedsQL child-total (8.4%; P = 0.104) and child-physical sections (8.6%; P = 0.189), but these were not statistically significant. There were no significant changes in the PODCI parent-derived pain (-3.2%; P = 0.504) and happiness sections (1.9%; P = 0.645). Conclusions: Multilevel surgery in ambulatory patients with CP improves function and HRQOL. However, improved functional well-being does not imply improved psychosocial well-being, and patients and their families should be counseled accordingly. Level of Evidence: Therapeutic Level II.
