- Abstract
Aim: The purpose of this study is to report diagnostic pearls and review the clinical presentation and outcomes of surgical treatment of paediatric trigger thumbs., Methods: A retrospective review of medical records and imaging studies was performed on children with trigger thumbs from January 2009 to December 2019., Results: Sixty-four trigger thumbs in 52 consecutive patients were treated. The average age at referral was 2.5 years. Symptoms include pain (4), triggering (14) and fixed contracture (38). The average symptom duration was 8 months. Forty patients had been evaluated and referred by a paediatrician or primary care doctor. Twenty-four of the 52 (46%) patients received hand x-rays and were initially misdiagnosed as a fracture or dislocation. Physical exam demonstrated a volar nodule in 64 thumbs (100%), fixed flexion deformities in 38 (73%) thumbs and triggering with active extension of the interphalangeal joint in 14 (27%) thumbs. The average age at surgery was 3.2 years. Follow-up averaged 12 months. Surgery resulted in complete relief of symptoms and correction of deformity. There was no reported loss of function or complication., Conclusions: Children with trigger thumbs who ultimately undergo surgery present with distinct physical exam findings, including a volar nodule and a fixed flexion contracture. Understanding these pearls can minimise misdiagnosis of the condition as a fracture or dislocation. Highlighting trigger thumbs during musculoskeletal education for paediatric and primary care physicians is recommended. Surgical outcomes were excellent in patients aged 2-8 years old., (© 2024 The Author(s).

- Abstract
The purpose of this study was to define pediatric orthopaedic transfer criteria for patients coming from a smaller facility to a Level I pediatric trauma center. A 10-question phone survey was utilized for every transfer request. Fifty-eight transfer requests were prospectively collected and retrospectively reviewed. The criteria were based on The American Academy of Pediatrics (AAP) guidelines and the expert opinion of the senior author. The AAP criteria included complex fractures/dislocations and bone and joint infections. The expert opinion criteria included a patient requiring admission to the hospital or a patient needing surgery. All centers requesting transfers were staffed by an on-call board-certified general orthopaedic surgeon with the ability to care for pediatric orthopaedic injuries. Of the 58 transfers, 37 (64%) did not meet transfer criteria; 21 (36%) met transfer criteria. Transfer requests came from Emergency Department (ED) physicians in 25/58 cases (43%), physician assistants in 11/58 (19%), orthopaedic attending physicians in 3/58 (5%), and orthopaedic residents in 3/58 (5%). The orthopaedic surgeon at the referring hospital examined the patient in only six instances (10%) prior to transfer. Of the 58 patients, 18 (31%) required a hospital admission, and 17 (29%) patients were indicated for surgery. In the current study, 64% of pediatric orthopaedic transfers did not meet criteria for an inter-facility hospital to hospital transfer and were potentially avoidable.

- Abstract
Tibial tubercle fractures are uncommon injuries. The purpose of this study is to report the outcomes of surgical treatment of displaced tibial tubercle fractures in adolescents. This study was approved by the College of Medicine Institutional Review Board. A retrospective review was performed at our institution for patients who underwent surgical treatment of tibial tubercle fractures. Patient demographics, injury characteristics, and outcomes were recorded. A p -value of <0.05 was considered statistically significant. Nineteen male patients were identified. The average age was 14.6 years, and the average body mass index was 25.8. Basketball (63%) was the most common mechanism of injury. No patient was treated with bicortical screws. Two patients had preoperative computed tomography. One patient presented with acute compartment syndrome (ACS), and fasciotomy was performed. Twelve patients (63%) without clinical signs of ACS received anterior compartment fasciotomy on a case-by-case basis according to surgeon's preference. No growth injury, including growth arrest, angulation, or shortening occurred. All patients returned to preinjury activities at an average of 18.5 weeks. Displaced tibial tubercle fractures in this series occurred in male adolescents during athletic activity. Unicortical screws/pins were used with no loss of fixation. Routine use of advanced imaging was unnecessary. One patient (5%) underwent fasciotomy. No growth arrest occurred. All patients returned to preinjury athletic activities., Competing Interests: None declared., (Thieme. All rights reserved.)

- Abstract
The purpose of this study was to analyze the demographics and backgrounds of U.S. orthopaedic surgery residency program directors (PDs). We collected publicly available information on 189 orthopaedic surgery residency PDs. Of those PDs, 90% were male MDs with an average age of 52. The average age at PD appointment was 45. The average duration of appointment was 7 years. About 81% of programs were university-affiliated, and 61% were in an urban environment. PDs attended 100 medical schools, 129 residencies, and 96 fellowships. of PDs, 87% completed fellowships, commonly in trauma and sports medicine. There was no significant difference between male and female PDs when comparing age, academic appointment, or urban/rural environment. Most female PDs (89%) were at university-based hospitals. Of PDs at osteopathic-focused programs, 28% had an MD/PD. No program with an allopathic focus had a DO/PD. Lastly, 38% of PDs worked at the center where they completed residency.

- Abstract
Introduction: Osgood-Schlatter disease (OSD) is a common cause of anterior knee pain in adolescent athletes due to repetitive stress on the tibial tubercle. The posterior tibial slope angle (PTSA) and the Insall-Salvati Index (ISI) play a role in knee biomechanics. However, to our knowledge, the posterior tibial slope and patellar height have not been compared in operated versus nonoperative OSD patients. The purpose of the current study is to compare the differences in the PTSA and the ISI between operative and nonoperative patients with OSD., Materials and Methods: The study was approved by the College of Medicine's Institutional Review Board. A retrospective review was performed on 75 adolescent athletes with OSD between 2008 and 2019. The data extracted included: age, sex, body mass index (BMI), sporting activity and type, mechanism of injury (MOI), chronicity of symptoms, PTSA, and the ISI. Descriptive and quantitative statistics were used., Results: Seventy-five patients (88 knees) with OSD were studied (28 boys, 47 girls). The average age was 12.2 years and the average BMI was 22.3. The mechanism of injury (MOI) included repetitive stress (77%) and trauma (23%). The duration of knee pain averaged 10.3 months. Sixty-six patients were included in the nonoperative cohort. Nine patients were included in the operative cohort and underwent surgery due to persistent symptoms after skeletal maturity with tubercleplasty and/or ossicle excision. The average PTSA was 12.1° ± 1.7° and average ISI was 1.05 ± 0.15. Comparing the operative and nonoperative patients, we found no significant difference in PTSA (11.2° ± 0.73° versus 12.8° ± 1.8°, p < 0.064). However, we did find that patients treated operatively had a lower ISI (0.95 ± 0.18 versus 1.14 ± 0.13, p < 0.001)., Conclusion: In patients with OSD, operative and nonoperative patients demonstrated a similar PTSA. On the other hand, the ISI was higher in nonoperative patients. In the current paper, a decreased ISI was helpful in predicting the need for operative intervention in symptomatic patients after skeletal maturity., (© 2021.

- Abstract
In 2004, Reeder and in 2012, Schwend reported that inappropriate nonsurgical referrals to pediatric orthopedic clinics create a misuse of resources. Additional authors have called for re-emphasis and additional training in musculoskeletal medicine for primary care physicians (PCP) to improve the confidence, knowledge and performance when managing musculoskeletal conditions. The current study compares the diagnoses referred to a pediatric orthopedic clinic with diagnoses recommended for referral by the American Academy of Pediatrics (AAP) guidelines to determine if any improvement in the quality of referrals has occurred since Reeder and Schwend's article. A chart review of new referrals to a pediatric orthopedic clinic during a 3-month-period was performed. Data were collected on age, sex, referring diagnosis, referral source, final diagnosis and treatment. In total 230 new consults were evaluated. The referral source was a PCP in 169 (73.5%) cases, 30 (13%) self-referrals by a parent, 19 (8.3%) from another orthopedic surgeon, 9 (3.9%) from a neurologist and 3 (1.3%) from another specialist. Fifty percent of referrals met the criteria outlined in the AAP guidelines for referral to a pediatric orthopedic specialist and 48% were classified as primary care musculoskeletal conditions. During the 15 years since the publication of Reeder's study and despite a limited re-emphasis on musculoskeletal education, the percent of inappropriate referrals to a pediatric orthopedic clinic remains unchanged at 50%. We support an expanded musculoskeletal educational effort aimed at the medical, resident and pediatrician level, online decision-making aids, and implementation of a standardized referral form with the specific criteria of the AAP included., (Copyright © 2022 Wolters Kluwer Health, Inc.

- Abstract
Developmental hip dysplasia (DDH) is a paediatric condition in which the 'ball and socket' hip joint fails to form properly during infancy. The increased mechanical stress on the hip joint from DDH can contribute to the development of osteoarthritis during adulthood. Therefore, careful physical examination and imaging of all infants to diagnose DDH is critical to provide the best possible functional outcome. Ultrasonography (US) is a useful diagnostic test in providing a real-time evaluation and three-dimensional view of the hip in infants less than 4 months. In infants with a normal hip ultrasound, the risk of subsequent development of hip dysplasia at an older age and the need for further follow-up is assumed to be unnecessary. In the present study, we report 2 cases of late presenting DDH in infant girls born breech with a previous normal hip exam and normal hip ultrasound at 6 weeks of age., (© 2022 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

- Abstract
The purpose of this study was to evaluate the efficacy and accuracy of mandated reporters to identify child abuse in children presenting with fractures. An Institutional Review Board approved survey-based study between January 2017 and December 2017 was conducted at a tertiary care academic medical center. 10 cases were combined to create one survey. Each case had information on presentation history, radiographic data, and social history. This study assesses the ability of 13 orthopedic residents and 11 medical students to diagnose child abuse. Participants had the option to explain their reasoning for a given case. To evaluate decision-making reasoning, we split responses into three cohorts, encompassing objective evidence, subjective evidence, or social evidence. Twenty-four participants completed the survey; 203 out of 240 (85%) included the rationale for the diagnosis of child abuse. The observed diagnostic odds ratio was 0.83 for medical students, 0.93 for junior residents, and 0.96 for senior residents. There was no statistically significant difference in diagnosing child abuse between a participant's level of experience, age, or whether participants had their own children. Participants who used more than one source of evidence were significantly more likely to make the correct diagnosis (P = 0.013). Participant decisions were no more accurate than a coin toss. The use of several data sources led to increased diagnostic accuracy. There is low accuracy in correctly diagnosing child abuse in our cohort of mandated reporters. Participants who highlighted using several sources of evidence were more likely to diagnose child abuse accurately., (Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.)

- Abstract
Bipartite patella affects about 2% of people. Most cases are asymptomatic; however, some develop anterior knee pain during sports. When conservative treatment fails, surgery can be considered. This study reports the outcomes of fragment excision with or without lateral release in teenage athletes with symptomatic bipartite patella. The study was approved by the College of Medicine Institutional Review Board. A retrospective review was performed. Patients were excluded if age >18 or had prior knee surgery. Data collected included age, gender, BMI, sports played, Saupe classification, conservative and surgical treatment, advanced imaging used, duration of follow-up, Lysholm Score and postoperative complications. Five teenage patients were studied. The average age was 15.6 years and BMI was 23. Sports played included basketball, football, track-and-field and soccer. All patients complained of anterior knee pain exacerbated by sports. All patients failed >6 months of conservative treatment. Saupe classification included four type III (superolateral) and one type II (lateral). Two patients had an MRI. Surgical treatment included two open excisions and three arthroscopic-assisted open excisions with lateral releases. The average Lysholm Score was 97. Postoperatively, all patients returned to presurgery sporting activity at an average of 9.8 weeks (range, 6-13 weeks). A 16-year-old male treated by open excision developed a postoperative wound infection. He was successfully treated with irrigation & debridement and antibiotics and returned to sports at 6 weeks. Symptomatic bipartite patella is an uncommon cause of anterior knee pain in adolescent athletes. When pain persists despite conservative care, fragment excision with or without lateral release resulted in excellent pain relief and return to full sporting activity in all cases., (Copyright © 2022 Wolters Kluwer Health, Inc.

- Abstract
The purpose of this study is to report the operative outcomes in a consecutive series of adolescent patients with symptomatic accessory navicular (AN). A retrospective review was conducted. Patient characteristics, operative techniques, and outcomes were recorded. Radiographs were used to identify the type of AN, skeletal maturity, and presence of concurrent pes planus. Twenty-two patients and 24 feet were studied. All 22 patients had an excision of the AN, and 19 patients had an additional reefing of the tibialis posterior tendon. At final follow up, 22 cases reported no pain, one had minimal pain, and one reported no change in pain. Symptomatic AN is more common in females. Surgery technique was not correlated with postoperative pain. Surgery eliminated pain in 91% of patients and can be safely performed in athletes with high rate of return to their previous athletic performance.

- Abstract
The United States Medical Licensing Examination (USMLE) Step 1 examination will transition from graded to pass/fail scoring starting no earlier than January 2022. Orthopedic surgery residency programs will need to adapt to these changes. The goal of this study was to investigate the perceptions of orthopedic surgery residency program directors on the change of Step 1 from a graded to a pass/fail examination. We also investigated how the change would affect the other factors that are typically considered in the selection of orthopedic surgery residents. A survey was distributed to 161 directors of allopathic orthopedic surgery programs. Contact information was obtained from a national database. Of those contacted, 75 (46.6%) program directors responded. Most (85.3%) did not support the pass/fail change. Most believe that greater importance will be placed on the Step 2 Clinical Knowledge examination (96.0%), audition elective with their department (84.0%), personal knowledge of the applicant (78.7%), grades (74.7%), letters of recommendation from recognizable orthopedic surgeons (74.7%), and Alpha Omega Alpha status (69.3%). Most also believe that this change will advantage allopathic students who attend highly regarded schools (58.7%). Most of the program directors support a graded preclinical curriculum (69.3%) and caps on the number of orthopedic surgery residency applications (70.7%). Although most orthopedic surgery program directors disagree with the change to a pass/fail Step 1 examination, residency programs will need to reevaluate how they screen applicants for an interview once the scored Step 1 is no longer available. With this change, other factors, such as Step 2 score, audition rotations, and grades in clerkships, will be emphasized more heavily. [ Orthopedics . 2022;45(1):e30-e34.].

- Abstract
Objectives: To clarify the incidence, associated conditions, and timing of fasciotomy for compartment syndrome (CS) in children with a supracondylar (SC) fracture of the humerus., Design: A retrospective trauma system database study., Setting: Accredited trauma centers in Pennsylvania., Patients: A statewide trauma database was searched for children 2-13 years of age admitted with a SC fracture between January 2001 and December 2015. Four thousand three hundred eight children met inclusion criteria., Intervention: Treatment of a SC fracture., Main Outcome Measurement: Diagnosis of CS/performance of a fasciotomy., Results: During the study period, 21 (0.49%) children admitted with a SC fracture of the humerus were treated with fasciotomy. CS/fasciotomy was more likely in males (P = 0.031), those with a nerve injury (P = 0.049), and/or ipsilateral forearm fracture (P < 0.001). Vascular procedure, performed in 18 (0.42%) children, was strongly associated with CS/fasciotomy (P < 0.001). Closed reduction and fixation of a forearm fracture was associated with CS (P = 0.007). Timing of SC fracture treatment did not influence outcome. Fasciotomy was performed subsequent to reduction in 13 subjects; mean interval between procedures was 23.4 hours (r = 4.5-51.3)., Conclusions: Risk factors for CS exist; however, they are not required for the condition to develop. CS may develop subsequent to admission and/or SC fracture treatment. In timing of operative management and hospitalization, the results support contemporary practice., Level of Evidence: Prognostic Level III.

- Abstract
Background: United States Medical Licensing Examination Step 1 will transition from numeric grading to pass/fail, sometime after January 2022. The aim of this study was to compare how program directors in orthopaedics and internal medicine perceive a pass/fail Step 1 will impact the residency application process., Methods: A 27-item survey was distributed through REDCap to 161 U.S. orthopaedic residency program directors and 548 U.S. internal medicine residency program directors. Program director emails were obtained from the American Medical Association's Fellowship and Residency Electronic Interactive Database., Results: We received 58 (36.0%) orthopaedic and 125 (22.8%) internal medicine program director responses. The majority of both groups disagree with the change to pass/fail, and felt that the decision was not transparent. Both groups believe that the Step 2 Clinical Knowledge exam and clerkship grades will take on more importance. Compared to internal medicine PDs, orthopaedic PDs were significantly more likely to emphasize research, letters of recommendation from known faculty, Alpha Omega Alpha membership, leadership/extracurricular activities, audition elective rotations, and personal knowledge of the applicant. Both groups believe that allopathic students from less prestigious medical schools, osteopathic students, and international medical graduates will be disadvantaged. Orthopaedic and internal medicine program directors agree that medical schools should adopt a graded pre-clinical curriculum, and that there should be a cap on the number of residency applications a student can submit., Conclusion: Orthopaedic and internal medicine program directors disagree with the change of Step 1 to pass/fail. They also believe that this transition will make the match process more difficult, and disadvantage students from less highly-regarded medical schools. Both groups will rely more heavily on the Step 2 clinical knowledge exam score, but orthopaedics will place more importance on research, letters of recommendation, Alpha Omega Alpha membership, leadership/extracurricular activities, personal knowledge of the applicant, and audition electives.

- Abstract
Background: While supracondylar (SC) fractures are relatively common in children, the incidence of open injuries is believed to be only 1%. Two prior studies on open SC fractures in children reported an increased incidence of vascular injuries. The purposes of our study were to clarify the incidence, associated conditions, and current treatment for open SC fractures., Methods: The Pennsylvania Trauma Outcome Study database was queried. Subjects age 25 to 156 months old admitted to trauma centers between January 2000 and December 2015 with a SC fracture were included. Controls were those with closed fractures and the study group, those with open injuries. Study variables were age, sex, weight, injury severity score, length of stay (LOS), nerve injury, ipsilateral forearm fracture, compartment syndrome/fasciotomy, requirement for a vascular procedure. Other variables were mode of treatment, provisional reduction, repeat reduction, time interval between referring facility admission and operation, and time from emergency department admission to operation., Results: A total of 4308 subjects were included, 104 (2.4%) of whom had an open SC fracture. LOS was 2 days for the study group versus 1 day for controls (P<0.001). Open SC fractures were more likely than closed to be associated with a nerve injury (13.5% vs. 3.7%), ipsilateral forearm fracture (18.3% vs. 6.4%) and/or a vascular procedure (6.7% vs. 0.3%) (P<0.001). 5.9% of those in the study group required repeat surgery compared with 0.4% for controls (P<0.001). Time from emergency department admission to operation was 3.2 versus 10.3 hours (P<0.001)., Conclusions: We report the largest series to date of open SC fractures in children. Surgeons caring for such patients should be aware of their increased risks for both associated injuries and potential requirement for vascular reconstruction. The majority of children with an open SC fracture are managed with 1 operation and in the absence of vascular injury, seldom require an extended LOS., Level of Evidence: Level III-retrospective cohort study., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Mun F and Hennrikus WL
- Abstract
The purpose of this case series is to report the outcomes of ossicle excision and tubercleplasty for unresolved Osgood-Schlatter disease that has failed conservative treatment in six adolescent athletes. A retrospective chart review was completed, and data collected include age at onset of symptoms, age at surgery, sex, laterality, mechanism of injury, conservative treatment regimen, radiographic findings, sports played, time to return to sport, length of follow-up, and Lysholm score. Surgery involved an open ossicle excision, tubercleplasty, and repair of the patellar tendon to bone using a suture anchor. Postoperatively, patients were allowed to fully weight-bear in an extension knee brace for 4 weeks and then allowed to gradually resume activity. Four males and 2 females were studied. The right knee was involved in 3 cases and the left knee in 3. The average age at onset of symptoms was 15.8 (range 12-18) and at surgery was 17.3 (range 17-18). Radiographic findings included a large bump in 4 cases, an ossicle in 2, and free fragments at the tendon insertion in 3. Sports played included basketball, football, running, and dancing. All patients returned to sports at an average of 21 weeks and 6 days postsurgery (range 8-56). The average length of follow-up was 14.2 weeks (range 5-27). The average Lysholm score postsurgery was 97.2 (range 94-100). Surgical treatment of unresolved Osgood-Schlatter disease was successful in all patients. No patients reported any postoperative complications or additional surgery. For skeletally mature and symptomatic patients, we recommend removal of the ossicle and adjacent bursae, smoothing the bump, and repairing the patellar tendon to bone., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2021 Frederick Mun and William L.

- Abstract
Purpose: Supracondylar humerus (SCH) fractures are the most common elbow fracture in children; however, they rarely occur as open injuries. Open fractures are associated with higher rates of infection, neurovascular injury, compartment syndrome, and nonunion. The purpose of this study was to evaluate the treatment and outcomes of open SCH fractures in children., Methods: Between 2008 and 2015, four children (1%) had open injuries among 420 treated for SCH fractures at a single center. The mean patient age was six years (range, four to eight years). Two patients had Gustilo-Anderson grade 1 open fractures and two had grade 2 fractures. Tetanus immunization was up-to-date in all. First dose of intravenous antibiotics was given on average 3hr 7min after onset of injury (range, 1hr 38min to 8hr 15min). Time from injury to irrigation and debridement (I&D) and closed reduction and percutaneous pinning (CRPP) was on average 8hr 16min (range, 4hr 19min to 13hr 15min). All patients received 24-hour intravenous antibiotics. Pins were removed at four weeks and bony union occurred by six weeks., Results: After an average follow-up period of 12 months (range, 6 to 22 months), there were no infections, neurovascular deficits, compartment syndromes, cubitus varus deformities, or range of motion losses. All outcomes were excellent according to the Flynn criteria. Due to the unstable nature of open SCH fractures, a medial pin was used in all four cases. No loss of reduction or ulnar nerve injury occurred., Conclusion: Open injuries occur in approximately 1% of all SCH fractures in children. The authors recommend urgent intravenous antibiotics, I&D, and CRPP involving a medial pin to treat open SCH fractures. Excellent outcomes based on the Flynn criteria were obtained in four cases., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Pan et al.)

- Abstract
Introduction: Scurvy, or vitamin C deficiency, is rare. The goal of this study is to highlight the common risk factors and identify the orthopaedic presentation of scurvy in children., Methods: A retrospective chart and radiograph review was performed of all patients consulted to the pediatric orthopaedic service from 2010 to 2019 who ultimately had the diagnosis of scurvy confirmed by an abnormally low serum vitamin C level. Data extracted included: patient age, sex, neurological conditions, prematurity, psychiatric conditions, dietary abnormalities, bone pain, arthritis, limb swelling, inability to walk, skin changes, child abuse evaluations, radiographic findings, additional vitamin deficiencies, lab studies, additional tests, response to treatment. Descriptive statistics were performed., Results: Nine patients (7 males, 2 females) with scurvy were studied. The average age was 7 years (range 3 to 13 y). The average body mass index was 21.4 (range, 14 to 30). Five had autism, 2 had a neurological disorder. Two had been born premature. Two had a psychiatric disorder. Seven had an abnormal diet. One presented with bone pain. Four presented with limb swelling. Seven had unilateral and 2 had bilateral leg symptoms. Five presented with inability to walk. Six demonstrated skin changes with ecchymosis or petechiae. Three presented with gingival bleeding. Radiographic findings included subperiosteal hematoma in 2, ring epiphysis in 3, Pelkan spurs in 1, metaphyseal white lines (Frankel sign) in 6, and a metaphyseal zone of rarefaction (Trummerfeld zone) in 3. Seven had additional vitamin deficiencies including: A, B1, B6, B9, D, E, K, iron and zinc. Four had a bone marrow biopsy and 1 had lumbar puncture. All were anemic. The average erythrocyte sedimentation rate was 25.7 (range 6 to 35) and C-reactive protein was 1.5 (range 0.55 to 5.64). Six had a computed tomography, 3 had a magnetic resonance imaging. After treatment with vitamin C lasting 3.4 months (range, 2 wk to 7 mo), all symptoms gradually resolved, including leg pain and swelling. All children began to walk., Conclusion: The pediatric orthopaedic surgeon should have an increased awareness about the diagnosis of scurvy when consulted on a child with bone pain or inability to walk. The most common orthopaedic presentation was the refusal to bear weight, the most common radiographic finding was the metaphyseal line of increased density (Frankel sign) and treatment with vitamin c supplementation was excellent in all cases., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

- Abstract
Child abuse is one of the most common causes for child fatality in the United States. Inaccurate reporting of child abuse combined with scarcity of resources for child abuse evaluations can lead to unintended consequences for children and their families. The differential diagnosis of child abuse is varied. To our knowledge, there are no reports in the literature on Lyme disease mimicking child abuse. The current study presents the case of a child from an endemic area for Lyme disease presenting with skin bruising, fracture, and swollen knee. The child was reported for child abuse by the pediatrician and then referred to the orthopaedic surgeon for fracture care., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2021 Tommy Pan et al.)

- Abstract
How medical inter-professional (IP) education should be introduced to students is still a matter of research. We evaluated IP student attitudes before and after a busy "hands-on" clinical experience.During 3 separate trips, first/second year medical and physician assistant students and third/fourth year nursing students traveled to Central America to work together for 1 week in an underserved clinical setting. Student opinions on inter-professional education were obtained before and after Brigade-1 using the Readiness for Inter-professional Learning Scale validated questionnaire. From these results, a modified version of the survey was developed that included quantitative and qualitative responses. For brigades-2 and -3, students received this modified version of the survey pre and post brigade. Quantitative data was analyzed via paired student t test, and qualitative data was analyzed to identify emerging themes using constant comparative methodology by three separate investigators.No significant quantitative differences between IP student groups were observed in their evaluation of the importance of inter-professional education either before or after the brigades. Qualitative data noted pre-brigade expectations of positive IP, experiential and patient-centered cultural learning. Pre- and post-brigade student perspectives maintained a strong belief that high functioning IP care benefited the patient. Post-brigade perspectives revealed a shift in attitude from purely positive expectations to more practical aspects of teamwork, respect, and interpersonal relationships.Students believe that patient care benefits from IP collaboration. After a busy clinical experience requiring collaboration, students realized that functional teams require appropriate skills, roles, and respectful interpersonal relationships.

- Abstract
Background: Distal Salter-Harris (SH) II fractures of the tibia are common injuries in the pediatric population. The purpose of this study is to evaluate our treatment and outcomes of SH II fractures of the distal tibia., Methods: The study was approved by the medical school's institutional review board (IRB). Fifty-one distal tibia SH type II fractures were treated from 2003 to 2017. We performed a retrospective review of all patients. Patients with displacement less than 3 mm, on x-ray, were treated with a cast. Patients with displacement greater than or equal to 3 mm displacement were initially treated with closed reduction in the emergency department with conscious sedation. Patients were also categorized based on the mechanism of injury and complications were noted. Patients were followed for an average of 4 months (range, 4 weeks-28 months)., Results: Fifty-one patients, 28 females and 23 males, were included in the study, with a mean age of 9.4 years (range, 13 months-13 years) at presentation. The most common mechanism of injury was participation in sports (43%). Out of the 51 patients, 45 were minimally displaced and treated with cast. Six displaced fractures were treated with closed reduction. The mean displacement in the closed reduction group at presentation was 5.7 (range, 3- 8.8) mm. Five out of 6 patients had reduction to less than 3 mm. The overall complication rate was 1 out of 51 patients, 2%. When examining displaced fractures, the complication rate was 1 out of 6 patients, 17%., Conclusion: Most SH II fractures of the distal tibia are minimally displaced and do not need a reduction. 6/51 cases (12%) in the current study were displaced and were indicated for a reduction. Displacement greater than or equal to 3 mm can be treated with closed reduction followed by a cast; if closed reduction fails, open reduction is indicated. Displaced fractures have a small risk of growth arrest., Competing Interests: Declaration of Competing Interest This work is not from a prior or a duplication of a publication of the same or a very similar work.

- Abstract
The aim of this study is to report the rate and type of neurologic injury associated with flexion supracondylar fractures at a tertiary, university institution treated over a 10-year period. All supracondylar humerus fracture cases treated at our institution between January 2004 and January 2014 were retrospectively reviewed. Twenty-three flexion-type fractures were identified. Patient demographics as well as fracture classification, treatment modalities, and pre-and post-treatment neurologic status were analyzed. Twenty-three flexion-type supracondylar humerus fractures were identified and reviewed out of a total of 1000 supracondylar humerus fractures (2.3%). Details of the patients' neurologic status upon presentation demonstrated that 17 (74%) patients were intact and six (26%) patients presented with an ulnar neuropraxia. Zero type I fractures, one type II fractures (14.3%), and five type III fractures (33.3%) demonstrated an ulnar nerve palsy. Of these, all six nerve deficits resolved following treatment. One additional patient was identified with median nerve neuropraxia following treatment with closed reduction casting, which resolved following observation. A total of 4 (17.4%) patients were treated with closed reduction casting, 15 (65.2%) with closed reduction percutaneous pinning, and four (17.4%) with open reduction internal fixation. Flexion-type supracondylar fractures of the humerus are rare yet significant injuries. The 26% of patients who developed an ulnar neuropraxia following a displaced flexion supracondylar fracture were higher than previous studies reported in the literature. This increased prevalence may be due to the high rates of type III fractures reported in the current study. Level of evidence: III, Retrospective comparative cohort analysis.

- Abstract
Background: Medial epicondyle fractures are a common pediatric and adolescent injury accounting for 11% to 20% of elbow fractures in this population. This purpose of this study was to determine the variability among pediatric orthopaedic surgeons when treating pediatric medial epicondyle fractures., Methods: A discrete choice experiment was conducted to determine which patient and injury attributes influence the management of medial epicondyle fractures by pediatric orthopaedic surgeons. A convenience sample of 13 pediatric orthopaedic surgeons reviewed 60 case vignettes of medial epicondyle fractures that included elbow radiographs and patient/injury characteristics. Displacement was incorporated into the study model as a fixed effect. Surgeons were queried if they would treat the injury with immobilization alone or open reduction and internal fixation (ORIF). Statistical analysis was performed using a mixed effect regression model. In addition, surgeons filled out a demographic questionnaire and a risk assessment to determine if these factors affected clinical decision-making., Results: Elbow dislocation and fracture displacement were the only attributes that significantly influenced surgeons to perform surgery (P<0.05). The presence of an elbow dislocation had the largest impact on surgeons when choosing operative care (β=-0.14; P=0.02). In addition, for every 1 mm increase in displacement, surgeons tended to favor ORIF by a factor of 0.09 (P<0.01). Sex, mechanism of injury, and sport participation did not influence decision-making. In total, 54% of the surgeons demonstrated a preference for ORIF for the included scenarios. On the basis of the personality Likert scale, participants were neither high-risk takers nor extremely risk adverse with an average-risk score of 2.24. Participant demographics did not influence decision-making., Conclusions: There is substantial variation among pediatric orthopaedic surgeons when treating medial epicondyle fractures. The decision to operate is significantly based on the degree of fracture displacement and if there is a concomitant elbow dislocation. There is no standardization regarding how to treat medial epicondyle fractures and better treatment algorithms are needed to provide better patient outcomes., Level of Evidence: Level V.

- Abstract
Distal radius and ulna fractures are common injuries in children. Fractures typically involve the distal radius and ulna metaphysis or physis or a combination of the 2. The goals of treatment are aimed at achieving satisfactory anatomic alignment within defined parameters based on growth remaining. Nonoperative treatment approaches are recommended for most fractures, whereas surgical intervention is indicated for select cases. Potential issues with skeletal growth and bone remodeling are common. This article will offer evidence- and experience-based pearls regarding common closed fractures of the distal radius and ulna intended to benefit the community orthopaedic surgeon caring for children during the course of their on-call duties.

- Abstract
Background: Distal radius fractures are the most common injury in the pediatric population. The purpose of this study was to determine the variation among pediatric orthopaedic surgeons when diagnosing and treating distal radius fractures., Methods: Nine pediatric orthopaedic surgeons reviewed 100 sets of wrist radiographs and were asked to describe the fracture, prescribe the type of treatment and length of immobilization, and determine the next follow-up visit. κ statistics were performed to assess the agreement with the chance agreement removed., Results: Only fair agreement was present when diagnosing and classifying the distal radius fractures (κ=0.379). There was poor agreement regarding the type of treatment that would be recommended (κ=0.059). There was no agreement regarding the length of immobilization (κ=-0.004).Poor agreement was also present regarding when the first follow-up visit should occur (κ=0.088), whether or not new radiographs should be obtained at the first follow-up visit (κ=0.133), and if radiographs were necessary at the final follow-up visit (κ=0.163). Surgeons had fair agreement regarding stability of the fracture (κ=0.320).A subgroup analysis comparing various traits of the treatment immobilization showed providers only had a slight level of agreement on whether splint or cast immobilization should be used (κ=0.072). There was poor agreement regarding whether long-arm or short-arm immobilization should be prescribed (κ=-0.067).Twenty-three of the 100 radiographs were diagnosed as a torus/buckle fracture by all 9 surgeons. κ analysis performed on all the treatment and management questions showed that each query had poor agreement., Conclusions: The interobserver reliability of diagnosing pediatric distal radius fractures showed only fair agreement. This study demonstrates that there is no standardization regarding how to treat these fractures and the length of immobilization required for proper fracture healing. Better classification systems of distal radius fractures are needed that standardize the treatment of these injuries., Level of Evidence: Level II.

- Abstract
The incidence of iliopsoas tendonitis (IPT) has not previously reported following hip arthroscopy for femoroacetabular impingement with or without labral tears. (i) What is the incidence of IPT following hip arthroscopy; (ii) are there any demographic risk factors and (iii) are there any operative techniques that are risk for IPT? Retrospective study. Hip arthroscopy patients from 2005 to 2012 were included. Patients were diagnosed via physical examination findings and were excluded if they had pre-operative IPT. Records were reviewed for demographics, operative reports and operative procedures. All patients received either labral debridement, labral repair, osteoplasty or a combination of those procedures. A standardized rehabilitation protocol was used. Of 252 patients, 60 (24%) had IPT. Twenty-eight (47%) had symptom resolution with activity modification, physical therapy and NSAIDs. Thirty-two (53%) required corticosteroid injection at a mean of 25 weeks after surgery. Seven (12%) required revision arthroscopy and iliopsoas release to resolve the symptoms. There were no patient-specific risk factors, differences based on surgical technique, and number of portals did not matter. Patients should minimize exercises that activate the iliopsoas after hip arthroscopy. The cause of IPT could be related to unaddressed abnormal mechanics, tendon scarring or improper physical therapy. Further studies are needed to investigate the reasons for this, as well as specific techniques to lower its incidence. The incidence of IPT after hip arthroscopy has an incidence of 24%. Additionally, we provide readers with a rehabilitation protocol to minimize this complication., What Is Known About the Subject: This subject has not previously been described., What This Study Adds to Existing Knowledge: We are the first to report IPT after hip arthroscopy.

- Abstract
A long arm cast with the elbow extended is a useful but often forgotten technique to manage some pediatric fractures. Specifically, proximal forearm fractures of both the radius and ulna, olecranon fractures, flexion-type supracondylar fractures and type II Monteggia fractures are well managed in this manner. Although some of these fractures are seen infrequently, timely diagnosis and treatment are essential to prevent complications. In this article, we present a review of the evaluation and management of these fractures in children, and a description of the technique used to apply a long arm cast in extension.

- Abstract
Background: Septic arthritis of the knee in the pediatric patient is a diagnosis that requires prompt identification and treatment. The purpose of this study was to identify clinical and laboratory parameters that allow differential diagnosis of septic arthritis from non-septic arthritis in children., Methods: Fifty-four pediatric patients with atraumatic isolated knee pain were retrospectively identified at three institutions and diagnosed with septic arthritis (SA, N = 28), Lyme arthritis (LA, N = 11), or transient synovitis (TS, N = 15). Clinical and laboratory data were analyzed to identify which factors were most predictive of SA of the knee., Results: Fever at time of presentation, a negative anti-streptolysin-O (ASO), erythrocyte sedimentation rate (ESR) > 40 mm/hr, and C-reactive protein (CRP) > 20 mg/L were the most predictive factors for distinguishing between septic arthritis (SA) and non-septic arthritis (transient synovitis or Lyme arthritis). Elevated ESR and CRP were both significantly higher in patients with SA when compared to TS or LA., Conclusion: When evaluating children with atraumatic isolated knee pain, a combination of the above factors should be utilized when ruling out septic arthritis.

- Abstract
Most patients with untreated Lyme disease will experience joint symptoms. Owing to their resemblance in clinical presentation, Lyme arthritis and septic arthritis are often difficult to differentiate. However, their treatment is different. The elbow is rarely the first joint to present with symptoms. Therefore, Lyme disease is not commonly included in the differential diagnosis for children presenting with isolated elbow pain. The authors report 4 cases of monoarticular Lyme arthritis presenting in the elbow. There was an average delay of diagnosis of 4.75 days. Three cases were treated with oral antibiotics alone; 1 case was treated with unnecessary surgery due to uncertainty of the diagnosis and the delay in the laboratory performing the Lyme serology tests. The authors strongly recommend that Lyme serology be performed on an emergent basis to prevent unneeded surgery. [Orthopedics. 2018; 41(4):e511-e515.]., (Copyright 2018, SLACK Incorporated.)

- Abstract
The surgical approach for open reduction and internal fixation of lateral condyle fractures in children is controversial. Some authors recommend the lateral approach to the elbow over the posterior approach because of theoretical concern for injury to the vascular supply of the distal humerus and potential avascular necrosis (AVN). The purpose of this retrospective case series study is to report the outcomes of open reduction and internal fixation of displaced lateral condyle fractures of the humerus by the posterior approach. Fifteen consecutive cases were reviewed and the posterior approach resulted in minimal postoperative loss of motion, no angular deformity, cosmetic scars, and no AVN. We support that AVN occurs because of stripping of soft tissues from the lateral condyle fragment and not the approach used. Stripping of soft tissues is not required when using the posterior approach because of excellent visualization of the fracture reduction.

- Abstract
Alternative medicine in pediatrics is expanding, with chiropractic now a common choice for families seeking alternative medical care. Currently, there is sparse information in the literature exploring the role of chiropractic in orthopaedic pathology. The objective of this case series is to present pediatric patients who received treatment from chiropractors and orthopaedic physicians as well as to review the respective existing research. Data collected included chiropractic diagnosis, orthopaedic diagnosis, imaging studies, treatments, and complications. Twenty-three patients were studied. Scoliosis, Legg-Calvé-Perthes disease, developmental dysplasia of the hip, cerebral palsy, skeletal dysplasia, and slipped capital femoral epiphysis were diagnoses included. Children had multiple sessions of chiropractic for management of these conditions. The parents' perception for chiropractic was positive in every case. Delayed referral, misdiagnosis, adverse events from manipulative therapy, and ineffective treatments were observed in the present study. More research is indicated to validate chiropractic in children with orthopaedic pathology. (Journal of Surgical Orthopaedic Advances 27(1):58-63, 2018).

- Abstract
Background: Traumatic anterior shoulder instability from recurrent dislocations or subluxations is a debilitating problem for the teenage athlete. The risk of recurrent instability is high in this adolescent population. We performed a retrospective case series analysis of adolescent athletes with recurrent instability treated with open Bankart repair and evaluated functional outcomes as well as redislocation rates., Methods: The retrospective study included 21 teenage patients with Bankart lesions and recurrent anterior shoulder instability. There were 19 males (90%) and 2 females (10%) with an average age of 16 years (range, 14 to 18 y). Patients were evaluated based on Rowe and UCLA shoulder scores, return to previous level of sport, external rotation, and recurrence., Results: The average number of anchors used to repair the Bankart lesion was 3 (range, 2 to 5). One patient was lost to follow-up at 6 months after surgery. The remaining 20 patients all had at least 2-year follow-up. The recurrent instability rate was zero. In total, 100% of patients had an excellent result based on an average Rowe score of 96.5 points of 100 points (a score of 90 to 100 is an excellent result). In total, 100% of patients had good/excellent result based on an average UCLA shoulder score of 34 of 35 (a score >27 is a good/excellent result). At final follow-up, 7 patients (34%) had lost an average of 11 degrees of external rotation (range, 5 to 20 degrees) on the injured shoulder with the arm at the side compared with the noninjured shoulder., Conclusions: Contact teenage athletes with recurrent anterior shoulder instability can be treated with open Bankart repair with a low recurrence, excellent functional shoulder outcomes, and return to sport. A small amount of external rotation may be lost with this technique. Care must be taken when considering this method with throwing athletes (ie, quarterback or pitcher). The open Bankart should remain a viable alternative for the adolescent population with recurrent anterior instability., Level of Evidence: Level IV.

- Abstract
Anterior cruciate ligament (ACL) reconstructions are complex orthopedic procedures in which a proficient team is of vital importance. Outpatient surgical centers (OSCs) often provide orthopedic-specific teams; however, hospital operating rooms (ORs) commonly rotate staff. The purpose of this study was to compare the efficiency of pediatric ACL reconstructions between a surgical center and a hospital OR owned and directed by a single institution. Cases examined involved pediatric patients, aged 12 to 18 years (mean age, 15.9±1.5 years), who underwent ACL reconstructions by a single orthopedic surgeon from 2009 to 2014. Procedural efficiency was defined as shorter total OR time, less total staff, and fewer support staff changes. Total OR time was also broken into 3 distinct time periods: in-room to incision time, total procedure time, and stop time to out-of-room time. A total of 49 ACL reconstructions were performed in healthy athletes, with 28 surgeries at the OSC (mean age, 15.7±1.3 years) and 21 surgeries in the hospital OR (mean age, 16.1±1.8 years). Overall efficiency was higher at the OSC, with total OR time improved by 30 minutes on average (P=.0001) with less total staff (P=.0002). Surgical technician and nursing changes occurred 6 and 2.5 times more often in the hospital OR, respectively. Procedural efficiency was greater at the OSC.

- Abstract
The resident curriculum of the American Board of Orthopaedic Surgery emphasizes radiation safety. Gendelberg showed that, immediately after a program on fluoroscopic safety, residents used less radiation when using the mini C-arm to reduce pediatric fractures. The current study evaluated whether this effect lasted. Residents underwent a new annual 3-hour session on mini C-arm use and radiation. Group A included 53 reductions performed before training. Group B included 45 reductions performed immediately after training. Group C included 46 reductions performed 11 months later. For distal radius fractures, exposure time and amount were 38.1 seconds and 83.1 mR, respectively, for group A; 26.7 seconds and 32.6 mR, respectively, for group B; and 24.1 seconds and 40.0 mR, respectively, for group C. When radiation time and amount were compared between group B and group C, P values were .525 and .293, respectively. When group C and group A were compared, P values were <.05 and <.01, respectively. For both bone forearm fractures, exposure time and amount were 41.2 seconds and 90.9 mR, respectively, for group A; 28.9 seconds and 30.4 mR, respectively, for group B; and 31.2 seconds and 43.6 mR, respectively, for group C. When radiation time and amount were compared between group B and group C, P values were .704 and .117, respectively. When group C and group A were compared, P values were .183 and .004, respectively. No significant difference in radiation exposure was noted immediately after training vs 11 months later. A sustained decrease in radiation exposure occurred after an educational program on safe mini C-arm use. [Orthopedics. 2017; 40(5):e788-e792.]., (Copyright 2017, SLACK Incorporated.)

- Abstract
Objectives: To determine the need for computerized tomography (CT) scans in the assessment of pediatric pelvic fractures., Design: Retrospective Chart Review., Setting: Level-1 Pediatric Trauma Center., Patients/participants: Thirty pediatric trauma patients with pelvic fractures who have obtained both a radiograph and CT scan., Main Outcome Measurements: Fleiss Kappa coefficient to compare interreliability., Results: The average age of the patients was 7 years (range 1-13 years). Seventeen were males and 13 were females. The Torode and Zieg classification included 3 type I, 6 type II, 13 type III, and 8 type IV. The Kappa value for interobserver agreement comparing radiographs was 0.453, and for CT was 0.42. Three patients (10%) were treated with a spica cast, and none required surgery for their pelvic fracture. Four patients (11%) demonstrated liver, spleen, or kidney injuries on CT. Out of those 4, 1 had indications for laparotomy and drain placement, 1 died secondary to shock, and 2 were treated conservatively., Conclusions: The results of this study demonstrated that plain radiographs alone can be used to classify and manage most pediatric fractures, confirming Silber previous findings. Furthermore, we recommend the specific instances of Schreck and Haasz et al in which CT scans should be used, sparing the general pediatric population unnecessary radiation. Such cases include patients with an abnormal abdominal or pelvic examination, complex fracture patterns, displacement greater than 1 cm, femur deformities, hematuria, Glasgow Coma Scale <13, hemodynamic instability, an aspartate aminotransferase > 200 U/L, an Hct < 30%, or an abnormal chest x-ray.

- Abstract
Shoulders are the most common major joint to become disarticulated, and shoulder dislocation is a frequent patient presentation to the ED. Bilateral shoulder dislocations, however, are rare and typically caused by seizure activity or electrocution. Posterior disarticulation is most common following seizure activity. This article describes an adolescent girl who dislocated both shoulders anteriorly following seizure activity.

- Abstract
Purpose: The purpose of this study is to report the spectrum of injuries sustained by competitive paediatric motocross athletes at a level I trauma centre., Patients and Methods: A retrospective study of paediatric competitive motocross injuries treated at a level I trauma centre between 2004 and 2014 was performed. Athletes were included if aged less than 18 years and injured while practising or competing on a competitive motocross track. Medical records were reviewed for age, gender, race, location of accident, use of safety equipment, mechanism of injury, injury type and severity, Glasgow Coma Score at hospital presentation and Injury Severity Score (ISS)., Results: In total, 35 athletes were studied. The average age was 14 years. One athlete died. Thirty athletes were injured during competition; five were injured during practice. Twenty-four athletes (69%) suffered an orthopaedic injury with a total of 32 fractures and two dislocations. Two fractures were open (6.3%). Lower extremity fractures were twice as common as upper extremity fractures. Surgery was more common for lower extremity fractures-83% versus 30%. The most common fractures were femoral shaft (18.8%), fibula (12.5%), clavicle (12.5%), tibial shaft (9.4%) and forearm (9.4%)., Conclusions: Competitive paediatric motocross athletes suffer serious, potentially life-threatening injuries despite the required use of protective safety equipment. Femoral shaft, fibula and clavicle were found to be the most commonly fractured bones. Further prospective research into track regulations, protective equipment and course design may reduce the trauma burden in this athlete population.

- Abstract
Background: The pucker sign, also called skin tenting, indicates significant displacement of the supracondylar fracture and can be a cause for alarm. The purpose of this study is to compare a cohort of patients with type III supracondylar fractures presenting with a pucker sign to a group without a pucker sign by evaluating neurovascular injury at presentation, need for open reduction, persistent neurovascular injury, range of motion, and carrying angle at final follow-up., Methods: A retrospective review was performed for Gartland type III extension type supracondylar fractures. Those with a pucker sign were identified and evaluated. Type III supracondylar fractures with a pucker sign were compared with a similar cohort without a pucker sign., Results: In total, 12 patients with a pucker sign at an average age of 5.2 years were evaluated. A total of 11 patients (92%) had diminished or absent pulses, and 2 (17%) had weakness in the median nerve distribution. Nine (75%) patients in this group were transferred to the university hospital. Average time to surgery was 8.9 hours with an average operating time of 25.1 minutes. Open reduction was not needed in any case. At an average follow-up of 4.7 months no patients had persistent neurovascular compromise. Two patients lacked <5 degrees of extension and 1 lacked 10 degrees of extension. One patient lacked 10 degrees of flexion. No patients had a change in carrying angle difference compared with the contralateral side. No statistical differences were observed between the 2 groups., Conclusions: Pucker sign, in the context of a supracondylar fracture of the humerus, is a soft tissue defect with potential entrapment of median nerve and brachial artery. At a maximum time of 16 hours from injury to surgery we report excellent outcomes and no long-term complications. Using the techniques of gradual traction, and milking the soft tissue, the pucker sign can be eliminated. Closed reduction and percutaneous pinning were performed in all the cases., Level of Evidence: Level III-retrospective comparative study.

- Abstract
Background: Accidents with lawnmowers can cause mutilating injuries to children. Safety guidelines regarding the use of lawnmowers were promoted by professional organizations beginning in 2001. The Pennsylvania Trauma Systems Foundation maintains a database including all admissions to accredited Levels 1 to 4 trauma centers in the state. The annual rates of admission for children in our state and the severity of injuries subsequent to introduction of safety guidelines have not been reported, to our knowledge. Ride-on lawnmowers have been associated with more severe injuries in children., Questions/purposes: We asked: (1) What was the incidence of hospital admissions for children with lawnmower-related injuries during 2002 to 2013 and did the incidence vary by age? (2) What was the severity of injuries and did the severity vary by age? (3) How often did these injuries result in amputation? (4) What types of lawnmowers were involved?, Methods: This was a retrospective study using a statewide trauma registry. We queried the Pennsylvania Trauma Outcome Study database for children 0 to 17 years old admitted to trauma centers in Pennsylvania between January 2002 and January 2014 with injuries resulting from lawnmower-related accidents. All accredited Levels 1 to 4 trauma centers in the state are required to submit their data to the Pennsylvania Trauma Systems Foundation which maintains the Pennsylvania Trauma Outcome Study database. Demographic information, Injury Severity Scores, International Classification of Diseases procedure codes, and injury location codes were recorded. Type of lawnmower was determined from the narratives and was identified in 60% (119/199) of patients. Traumatic and surgical amputations performed during the index hospitalization were included in the analysis. Information on later surgeries was not available. Subjects were stratified by age: 0 to 6, 7 to 12, and 13 to 17 years old., Results: The incidence of lawnmower injuries in Pennsylvania was a median five of 100,000 children (range, 4-12/100,000) during the study period. The median age was 6 years (range, 1-17 years). The median Injury Severity Score was 4 (range, 1-75). Children 0 to 6 years old had higher median Injury Severity Scores (median, 8; range, 1-75) compared with those 13-17 years old (median, 4; range, 1-20; difference of the medians, 4; p < 0.001). A total of 53% of the patients (106/199) underwent at least one amputation. There were 83 amputations in or of the foot, 18 in the leg, 14 in the hand, and three in the arm. Ride-on lawnmowers accounted for 92% (110/119) of mowers identified by type., Conclusions: The incidence of serious injuries to children owing to lawnmower-related trauma did not change during the 12-year study period. If children younger than 6 years had not been near the lawnmower and those younger than 12 years had not been operating one, at least 69% of the accidents might have been prevented. We recommend annual publicity campaigns during spring to remind the public of the dangers of lawnmowers to children., Level of Evidence: Level IV, therapeutic study.

- Abstract
Background: Open reduction and internal fixation of displaced medial epicondyle fracture dislocations in adolescents is recommended for incarceration of the epicondyle in the joint and for athletes who need a stable elbow for their sport. A screw placed across the epicondyle into the medial column avoiding the olecranon fossa is a common fixation method. One author has recommended adding a metal washer to the screw fixation because of the perceived risk of epicondyle fragmentation or penetration when using a screw alone. The purpose of this study was to determine whether the use of a screw and washer for the fixation of pediatric medial epicondyle fractures results in less fragmentation of the epicondyle at the time of surgery and more complaints of hardware prominence leading to a second surgery to remove a deep implant., Methods: A retrospective review was performed of patients treated surgically for displaced medial epicondyle fracture dislocations between 2008 and 2014., Results: Sixteen patients with a total of 17 fracture dislocations were included in the study. The average follow-up was 11.5 months. Twelve fractures were treated with a screw and washer and 5 fractures were treated with a screw alone. All fractures healed. No fracture treated with a screw alone resulted in fragmentation or penetration of the epicondyle fragment. Seven of 12 patients treated with a screw and washer requested deep metal removal due to prominence and irritation at the medial epicondyle. No patient treated with a screw alone requested metal removal (58% vs. 0%; P=0.04)., Conclusions: One author suggested that adding a washer to the screw for fixation of medial epicondyle fractures improved the ability to safely compress the fragment. However, the results of the present study report no case of fragmentation or penetration of the epicondyle when a washer was not used. In addition, the use of a screw and washer significantly increased the likelihood of a second surgery for removal of prominent hardware., Level of Evidence: Level IV.

- Abstract
Introduction: Because of the risk of developmental dysplasia of the hip in infants born breech-despite a normal physical exam-the American Academy of Pediatrics (AAP) guidelines recommend ultrasound (US) hip imaging at 6 weeks of age for breech females and optional imaging for breech males. The purpose of this study is to report US results and follow-up of infants born breech with a normal physical exam., Methods: The electronic medical record for children born at 1 hospital from 2008 to 2011 was reviewed. Data were analyzed for sex, birth weight, breech position, birth order, ethnicity, US and x-ray results, follow-up, and cost., Results: A total of 237 infants were born breech with a normal physical examination, all delivered by cesarean section. Of the infants, 55% were male and 45% female. About 151 breech infants (64%) with a normal Barlow and Ortolani exam had a precautionary hip US as recommended by the AAP performed at an average of 7 weeks of age. Eighty-six breech infants (35%) did not have an US and were followed clinically. Of the 151 infants that had an US, 140 (93%) were read as normal. None had a dislocated hip. Two patients had a normal physical exam but laxity on US. These 2 patients were the only infants treated in a Pavlik harness. A pediatric orthopaedic surgeon followed those with subtle US findings and no laxity until normal., Conclusions: The decision by the AAP to recommend US screening at 6 weeks of age for infants with a normal physical exam but breech position was based on an extensive literature review and expert opinion. Not all pediatricians are following the AAP guidelines. The decision to perform an US should be done on a case-by-case basis by the examining physician. A more practical, cost-effective strategy would be to skip the US if the physical exam is normal and simply obtain an AP pelvis x-ray at 4 months., Level of Evidence: Level III-this is a case-control study investigating the outcomes of infants on data drawn from the electronic medical record.

- Abstract
The mini C-arm has become increasingly popular in the practice of orthopedics. To the authors' knowledge, its use in the pediatric orthopedic outpatient clinic has not been reported. The purpose of this study was to evaluate the practice efficiency and radiation exposure to the patient when the mini C-arm was used in the pediatric orthopedic outpatient clinic. One hundred consecutive midshaft and distal forearm fractures were evaluated by one orthopedic surgeon in follow-up using a mini C-arm. For each case, the radiation physicist calculated the amount of skin exposure in milligray (mGy). The average skin exposure to the patient from the mini C-arm was 0.58 mGy, compared with 0.2 mGy for anteroposterior view and lateral view radiographs. Use of the mini C-arm, in place of plain radiographs obtained in the radiology department, decreased time waiting during clinic visits by 23 minutes. This study reports 2 important findings. First, surprisingly, the mini C-arm used a slightly higher radiation dose than standard imaging with plain radiographs. Second, use of the mini C-arm saved time and improved the efficiency of the clinic visit. Overall, the mini C-arm improves quality and efficiency in the pediatric orthopedic outpatient clinic.

- Abstract
Objective: To evaluate in-toeing consults to a pediatric orthopedic clinic to determine the proportion that could be managed by a primary care physician., Study Design: A prospective registry was created for 143 consecutive children referred to a pediatric orthopedic clinic for "in-toeing." Each patient underwent a careful history and physical examination, which included a rotational profile. We recorded the final diagnosis, treatment offered, follow-up visit results, and the source of the referral., Results: After pediatric orthopedic evaluation, 85% of patients had a confirmed diagnosis of in-toeing, and 15% had a different final diagnosis. Seventy-four percent of patients had 1 consultation visit, 18% had 2, and 8% had >2 visits. None of the referred patients was a candidate for treatment by casting or surgery., Conclusion: In most cases, in-toeing is a normal variation of development that can be managed by counseling and observation by the primary care physician alone. Rare cases of severe in-toeing >2 standard deviations from the mean should likely still prompt referral to a pediatric orthopedic surgeon for potential intervention., (Copyright © 2016.
