Several controversies surround the evaluation and treatment of medial epicondyle fractures of the humerus in children. As is well established, the medial epicondyle is the point of attachment for the medial collateral ligament and flexor and pronator musculature, thereby conferring a potentially important role in elbow stability and wrist strength. Traditional x-ray evaluation has been shown to be inaccurate in measuring fracture displacement. While novel radiographic views or advanced imaging modalities may improve this accuracy, the role of displacement in guiding treatment decisions remains unclear. Previous literature on medial epicondyle fractures-all of which is level III or IV evidence-suggests that outcomes may be similar between operative and non-operative treatment. However, most studies are hamstrung by inadequate power, potential for bias, or evaluation of antiquated surgical techniques. In the face of these uncertainties, a shared decision should be made with the patient and family after thorough consideration of treatment goals and discussion of the benefits and disadvantages of both surgical and non-surgical care. Prospective studies are underway and hope to provide clarity on the many debates surrounding this injury.

Background: Previous studies have reported disparities in orthopaedic care resulting from demographic factors, including insurance status. However, the effect of insurance on pediatric tibial spine fractures (TSFs), an uncommon but significant injury, is unknown. Purpose: To assess the effect of insurance status on the evaluation and treatment of TSFs in children and adolescents. Study Design: Cross-sectional study; Level of evidence, 3. Methods: We performed a retrospective cohort study of TSFs treated at 10 institutions between 2000 and 2019. Demographic data were collected, as was information regarding pre-, intra-, and postoperative treatment, with attention to delays in management and differences in care. Surgical and nonsurgical fractures were included, but a separate analysis of surgical patients was performed. Univariate analysis was followed by purposeful entry multivariate regression to adjust for confounding factors. Results: Data were collected on 434 patients (mean ± SD age, 11.7 ± 3.0 years) of which 61.1% had private (commercial) insurance. Magnetic resonance imaging (MRI) was obtained at similar rates for children with public and private insurance (41.4% vs 41.9%, respectively; P ≥.999). However, multivariate analysis revealed that those with MRI performed ≥21 days after injury were 5.3 times more likely to have public insurance (95% CI, 1.3-21.7; P =.02). Of the 434 patients included, 365 required surgery. Similar to the overall cohort, those in the surgical subgroup with MRI ≥21 days from injury were 4.8 times more likely to have public insurance (95% CI, 1.2-19.6; P =.03). Children who underwent surgery ≥21 days after injury were 2.5 times more likely to have public insurance (95% CI, 1.1-6.1; P =.04). However, there were no differences in the nature of the surgery or findings at surgery. Those who were publicly insured were 4.1 times more likely to be immobilized in a cast rather than a brace postoperatively (95% CI, 2.3-7.4; P <.001). Conclusion: Children with public insurance and a TSF were more likely to experience delays with MRI and surgical treatment than those with private insurance. However, there were no differences in the nature of the surgery or findings at surgery. Additionally, patients with public insurance were more likely to undergo postoperative casting rather than bracing. [ABSTRACT FROM AUTHOR]

Background: Metastatic bone disease is a substantial burden to patients and the healthcare system as a whole. Metastatic disease can be painful, is associated with decreased survival, and is emotionally traumatic to patients when they discover their disease has progressed. In the United States, more than 250,000 patients have metastatic bone disease, with an estimated annual cost of USD 12 billion. Prior studies suggest that patients who receive prophylactic fixation for impending pathologic fractures, compared with those treated for realized pathologic fractures, have decreased pain levels, faster postoperative rehabilitation, and less in-hospital morbidity. However, to our knowledge, the relative economic utility of these treatment options has not been examined.Questions/purposes: We asked: (1) Is there a cost difference between a cohort of patients treated surgically for pathologic fractures compared with a cohort of patients treated prophylactically for impending pathologic lesions? (2) Do these cohorts differ in other ways regarding their utilization of healthcare resources?Methods: We performed a retrospective study of 40 patients treated our institution. Between 2011 and 2014, we treated 46 patients surgically for metastatic lesions of long bones. Of those, 19 (48%) presented with pathologic fractures; the other 21 patients (53%) underwent surgery for impending fractures. Risk of impending fracture was determined by one surgeon based on appearance of the lesion, subjective symptoms of the patient, cortical involvement, and location of the lesion. At 1 year postoperative, four patients in each group had died. Six patients (13%) were treated for metastatic disease but were excluded from the retrospective data because of a change in medical record system and inability to obtain financial records. Variables of interest included total and direct costs per episode of care, days of hospitalization, discharge disposition, 1-year postoperative mortality, and descriptive demographic data. All costs were expressed as a cost ratio between the two cohorts, and total differences between the groups, as required per medical center regulations. All data were collected by one author and the medical center's financial office.Results: Mean total cost was higher in patients with pathologic fractures (cost unit [CU], 642 ± 519) than those treated prophylactically without fractures (CU, 370 ± 171; mean difference, 272; 95% CI, 19-525; p = 0.036). In USD, this translates to a mean of nearly USD 21,000 less for prophylactic surgery. Mean direct cost was 41% higher (nearly USD 12,000) in patients with a pathologic fracture (CU, 382 ± 300 versus 227 ± 93; mean difference, 155; 95% CI, 9-300; p = 0.038). Mean length of stay was longer in patients with pathologic fractures compared with the group treated prophylactically (8 ± 6 versus 4 ± 3 days; mean difference, 4; 95% CI, 1-7; p = 0.01).Conclusions: These findings show economic and clinical value of prophylactic stabilization of metastatic lesions when performed for patients with painful lesions compromising the structural integrity of long bones. Patients sustaining a pathologic fracture may represent a more severe, sicker demographic than patients treated for impending pathologic lesions.Level Of Evidence: Level IV, economic and decision analysis.

Background: Type I tibial spine fractures are non-displaced or minimally displaced (≤ 2mm displacement) fractures of the tibial eminence and ACL insertion traditionally managed nonoperatively with immobilization. Hypothesis/Purpose: We hypothesized that type I fractures do not carry significant risk of associated injuries and therefore do not require additional interventions aside from immobilization. Methods: We reviewed 52 patients classified by their treating institution with type I tibial spine fractures presenting between January 1, 2000 and January 31, 2019 at 10 institutions. Patients of age ≤ 18 years with pre-treatment plain radiographs and at least one year of follow-up were included. Data was collected on patient demographics, injury mechanism, treatment details, presence of concomitant injuries, range of motion (ROM) at final follow-up, treatment complications, and any return to the operating room for the injured knee. Pre-treatment imaging was reviewed by four authors to assess agreement of classification among the treating institutions. Patients were subclassified into two groups to ensure outcomes represented classic type I fracture patterns. Any patient with universal agreement among the four authors that the fracture did not appear consistent with a type I classification were assigned to Type 1+ Group (T1+). All other patients were assigned to the True Type I Group (TT1). We evaluated concomitant injury, need for operative intervention, and treatment outcomes overall and for each group independently. Results: 48 patients met inclusion criteria. 40/48 were TT1 fractures, while 8/48 were T1+ fractures, indicating less than universal agreement among sports specialists in classification of these fractures. Among TT1 patients, 7 of 40 (18.4%) underwent surgical treatment, though this represented 35.7% (5/14) of those who had undergone pretreatment advanced imaging. In the T1+ group, 6 of 8 (75%) underwent surgical treatment, 50% of whom (3/6) had pretreatment advanced imaging. Overall, twelve of 48 patients (25%) had concomitant injuries, nine TT1 patients and three T1+ patients (p=0.77), with 7 concomitant injuries requiring additional surgical management. Conclusions: Classification of type I fractures can be challenging. Nonetheless, a substantial percentage of patients with these fractures (>20%) were found to have concomitant injuries by advanced pretreatment imaging, with surgical management indicated in 58.3% of these patients. Contrary to traditional thought, type I tibial spine fractures do carry a risk of associated injuries. Simple cast immobilization may not be the ideal treatment in all cases. Advanced imaging would be beneficial for those whose plan of care may initially be non-operative treatment. [ABSTRACT FROM AUTHOR]

Background: When operative treatment is indicated, tibial spine fractures can be successfully managed with open or arthroscopic reduction and internal fixation. Hypothesis/Purpose: We hypothesized both approaches can lead to satisfactory outcomes for fracture healing, but that open treatment without preoperative advanced imaging can potentially lead to missed concomitant injuries. Methods: We performed an Institutional Review Board (IRB)-approved retrospective cohort study of pediatric tibial spine fractures presenting between January 1, 2000 and January 31, 2019 at 10 institutions. Patients were categorized into two cohorts based on treatment: arthroscopic reduction and internal fixation (ARIF) and open reduction and internal fixation (ORIF). Surgical outcomes, the incidence of concomitant injuries, and surgeon demographics were compared between groups. Results: There were 477 patients with tibial spine fractures who met inclusion criteria, 420 of whom (88.1%) were treated with ARIF, while 57 (11.9%) were treated with ORIF. Patients treated with ARIF were more likely to have an identified concomitant injury (41.4%) compared to those treated with ORIF (24.6%, p=0.021). Patients treated with ARIF were also more likely to have pre-treatment MRI (41.7% vs. 22.8%, p =0.010). Most concomitant injuries (74.5%) required surgical intervention. The most common treatment complications included arthrofibrosis (6.9% in ARIF patients, 7.0% in ORIF patients, p=1.00) and subsequent ACL injury (2.1% in ARIF patients and 3.5% in ORIF, p=0.86). The rate of complications, return to the operating room, and failure to return to full range of motion were similar between groups. Twenty surgeons with sports subspecialty training completed 85.0% of ARIF cases; the remaining 15.0% were performed by 12 surgeons without additional sports training. The majority (56.1%) of ORIF cases were completed by 14 surgeons without sports subspecialty training. Conclusion: This is the largest study comparing ARIF to ORIF in pediatric tibial spine fractures. This study demonstrated no difference in outcomes or nonunion following ARIF or ORIF for pediatric tibial spine fractures. There were significantly higher rates of concomitant injuries in patients treated with ARIF, however, these patients also had a higher rate of pre-treatment MRI. The majority of these concomitant injuries (74.5%) required surgical intervention. Pre-treatment MRI should be considered in the workup of tibial spine fractures to increase identification of concomitant injury. Concomitant injuries may be missed in tibial spine fractures treated with an open approach, especially in cases where preoperative advanced imaging is not obtained. Surgeon preference and training may impact treatment approach and identification and treatment of concomitant injury. [ABSTRACT FROM AUTHOR]

The article discusses a study evaluating the outcomes of operative and nonoperative management of medial epicondyle fractures in adolescent athletes. The study found that nonoperative treatment can be successful in young athletes with low-energy medial epicondyle avulsions, a stable elbow, and minimal fracture displacement, whereas surgical management can be successful in athletes who sustain more significant trauma, who have elbow laxity or instability.

Background: Spica casting and elastic stable intramedullary nailing (ESIN) are options for diaphyseal femur fractures in preschool-age children (ages 3-6 years). Clinical practice guidelines (CPG) are only of moderate or limited strength, which may lead to variation in practice. The purpose of this study is to analyze the epidemiology of children undergoing these procedures in the United States.Methods: The Pediatric Health Information System, a national database consisting of 49 children's hospitals, was queried for patients between the ages of 3 and 6 years undergoing spica casting or ESIN for a diaphyseal femur fracture between 2011 and 2017. Non-diaphyseal fractures, subjects with associated syndromes or neuromuscular disorders, and pathologic fractures were excluded. Census guidelines were used to categorize hospitals geographically into regions and divisions. Univariate analysis was followed by purposeful entry multivariate regression to adjust for confounders.Results: Analysis included 4059 subjects. Spica casting was performed in 2878 children (71%) and ESIN in 1181 (29%). The median age of those undergoing spica casting was 3.0 years [interquartile range (IQR) 1 year] compared to 5.0 years for ESIN (IQR 2 years; p<0.01). When adjusting for covariates in a multivariate model, each year of increasing age resulted in 4.4 times higher odds that ESIN would be performed (95% CI 4.0-4.8, p<0.01). Compared to the Northeast, a child in the Midwest had 3.6 times higher odds of undergoing ESIN rather than spica casting (95% CI 2.6-5.1, p<0.01). Age at time of ESIN was lowest in the Midwest and highest in the Northeast (4.8±1.0 versus 5.3±0.9 years; p<0.01). There was no variation in the ratio of spica casting to ESIN performed in this age group between 2011 and 2017, including after release of the 2015 CPG.Conclusions: In the United States, there is substantial variation in the chosen treatment for diaphyseal femur fractures in preschool-age children. ESIN is more likely to be chosen for older children. It is also most likely to be performed in the Midwest and least likely in the Northeast. These findings may have implications in terms of cost and resource utilization and suggest the need for more clinical data to guide surgical indications. [ABSTRACT FROM AUTHOR]
