RESUMO
This study aimed to assess the fusion of growth plates and the development of secondary ossification centres in the forelimb bones of maned wolves (Chrysocyon brachyurus), contrasting the findings with established data from domestic dogs. Three maned wolves, comprising one male and two females, initially aged between 3 and 4 months, were subjected to monthly radiographic evaluations until 10-11 months of age, followed by bimonthly assessments until 18-19 months of age, encompassing both forelimbs. The closure times of growth plates were observed as follows: supraglenoid tubercle (7-8 months), proximal humerus (17-19 months), distal humerus (8-9 months), medial epicondyle of the humerus (8-9 months), proximal ulna (9-10 months), proximal radius (13-15 months), distal ulna (13-15 months) and distal radius (17-19 months). Statistical analysis revealed significant differences in the areas of secondary ossification centres in the proximal epiphyses of the humerus and radius, respectively, observed from the initial evaluation at 8-9 months and 6-7 months. Conversely, the epiphyses of the supraglenoid tubercle, distal humerus, proximal ulna, distal ulna, medial epicondyle of the humerus and distal radius did not exhibit significant area differences between 3-4 months and 4-5 months, yet notable distinctions emerged at 5-6 months. In summary, while the radiographic appearance of epiphyseal growth plates and secondary ossification centres in maned wolves resembles that of domestic dogs, closure times vary. These findings contribute to understanding the dynamics of epiphyseal growth plates in this species.

Objective To evaluate the safety and reproducibility of the surgery for unstable slipped capital femoral epiphysis (SCFE) through the modified Dunn technique in a single center cohort from Brazil. Methods We retrospectively analyzed a cohort of patients submitted to this procedure by a single surgeon who was a hip preservation specialist. Demographic data and radiographic angles were evaluated for the relative risk (RR) of avascular necrosis (AVN) using a log-binomial regression model with simple and random effects. Results Among the 30 patients (30 hips) with a mean age of 11.79 years at the time of the operation, there were 17 boys and 18 left hips, which were operated on in a mean of 11.5 days after the slip. The mean follow-up was of 38 months. The preoperative Southwick angle averaged 60.69° against 4.52° postoperatively ( p < 0.001). A larger preoperative slip angle was associated with the development of AVN (RR: 1.05; 95% confidence interval [95%CI]: 1.02-1.07; p < 0.01). The overall AVN rate was of 26.7%. Function was good or excellent in 86% of uncomplicated hips, and poor in 87.5% of the partients who developed AVN, as graded by the Harris Hip Score. There was no statistical relationship between epiphyseal bleeding and AVN development ( p = 0.82). Conclusion The modified Dunn technique is associated with restoration of the femoral alignment and function after unstable SCFE, when uncomplicated. Moreover, it was shown to be reproducible in our population, with a rate of 26% of femoral head necrosis.

Resumo Objetivo Avaliar a segurança e a reprodutibilidade da cirurgia para escorregamento da epífise femoral proximal (EEPF) com instabilidade por meio da técnica de Dunn modificada em uma coorte unicêntrica no Brasil. Métodos Analisamos de forma retrospectiva uma coorte de pacientes submetidos a esse procedimento por um único cirurgião especialista em preservação do quadril. Avaliamos os dados demográficos e os ângulos radiográficos quanto ao risco relativo (RR) de necrose avascular (NAV) por meio do modelo de regressão log-binomial com efeitos simples e aleatórios. Resultados Entre os 30 pacientes (30 quadris) com idade média de 11,79 anos no momento da cirurgia, havia 17 meninos e 18 quadris esquerdos. O procedimento ocorreu em média 11,5 dias após o escorregamento. O tempo médio de acompanhamento foi de 38 meses. O ângulo de Southwick pré-operatório foi, em média, de 60,69° contra 4,52° após o procedimento (p< 0,001). O maior ângulo de escorregamento pré-operatório foi associado ao desenvolvimento de NAV (RR: 1,05; intervalo de confiança de 95% [IC95%]: 1,02-1,07; p< 0,01). A frequência geral de NAV foi de 26,7%. De acordo com a Escala de Quadril de Harris (Harris Hip Score), a função foi boa ou excelente em 86% dos quadris sem complicações, e ruim em 87,5% dos casos com NAV. Não houve relação estatística entre sangramento epifisário e desenvolvimento de NAV (p= 0,82). Conclusão A técnica de Dunn modificada restaura o alinhamento femoral e a função articular após o EEPF com instabilidade na ausência de complicações. Além disso, mostrou-se passível de reprodução em nossa população, com frequência de necrose da cabeça femoral de 26%.

Slipped Capital Femoral Epiphysis (SCFE) is a physeal disorder of the proximal femur. Misdiagnosis and late treatment are associated with poorer outcomes. The epidemiology and delays in treatment of the disease between 1968 and 2018 were investigated in North Trinidad. The number of cases presenting annually has increased over the decades and the incidence between 2008-2018 was 2.2 cases per 100 000 per year. Almost 70% of cases were above the 95th percentile for body weight. Delay in treatment from onset of symptoms was 278 ± 258 days. Awareness of the risk factors and clinical presentation of SCFE may facilitate early diagnosis and treatment, and prevent severe hip disability in adulthood.

RESUMO
Sport participation is an important part of the development, both physically and mentally, of children and adolescents in the United States. Illness and injury associated with sport and physical activities may occur in the school setting. Although most sport-related illness and injury in students are considered minor emergencies, life-threatening illnesses or injuries may occur. It is important for the school nurse to recognize potential life-threatening emergencies associated with sport and physical activity, to initiate stabilization of the student with life-threatening symptoms, and to triage these students to an appropriate level of care (back to the classroom, home with their guardian with follow up at their primary healthcare provider's office, or directly to the closest emergency department [ED] via Emergency Medical Services [EMS]). This article specifically describes the initial assessment and management of shoulder and hip injuries in pediatric athletes.

BACKGROUD: Slipped capital femoral epiphysis (SCFE) is a severe and catastrophic disorder that affects the hips of adolescents. Many reports about surgical procedures to treat this condition have been published, but to our knowledge, there are no published results of treatment in Latin American patients. This study describes the clinical and radiological results of the modified Dunn procedure with the surgical approach described by Ganz to treat mild to severe SCFE in a cohort of Colombian pediatric patients. METHODS: We retrospectively analyzed 21 patients (22 hips) with SCFE treated with surgical dislocation of the hip from 2005 to 2017. The same pediatric orthopedic surgeon performed all operations. Clinical outcome was assessed using the range of movement and Merle d'Aubigné score, while radiological measurements and assessment included the slip angle and Tönnis score. RESULTS: The average duration of follow-up was 29 months (range, 12-72 months). Of all cases, 17 presented with acute-on-chronic symptoms. Preoperatively, all 22 hips were classified as poor according to the Merle d'Aubigné score. Preoperative radiological classification showed compromise grade II or III in 20 hips. Last follow-up Merle d'Aubigné score rated 17 cases as good or excellent (p < 0.05). The postoperative radiological classification was grade I or II in all 22 cases, and the Tönnis score was stage II in 3 cases and stage III in 4 cases. CONCLUSIONS: Our results suggest that the modified Dunn osteotomy performed through the Ganz technique could be safely and effectively used to treat patients with mild to severe SCFE.

OBJECTIVE: To analyze the cases of slipped capital femoral epiphysis (SCFE) submitted to surgery at the Pediatric Orthopedics Surgery service of the Hospital Risoleta Tolentino Neves (HRTN), Belo Horizonte/MG, between 2016 and 2019. METHODS: Patients treated for SCFE at the HRTN between January/2016 and January/2019 participated in this study. The following data were collected: gender, age, affected side, procedure performed, and postoperative complications. RESULTS: Twenty-one patients were treated at HRTN during the specified period. Among these, most were female (57%) with mean age of 12 years. At the initial diagnosis, about 80% of the patients presented with chronic/acute-on-chronic epiphysis. The left hip was slightly more affected than the right (6:5), with a bilateral rate of 47%, and avascular necrosis was the most frequent complication, occurring in 33% of cases. CONCLUSION: Slipped femoral capital epiphysis is associated with high morbidity; thus, early diagnosis, endocrine disorder investigation, and appropriate surgical treatment are key for improving these patients' clinical and functional outcome. Level of Evidence II, Retrospective study.

RESUMO
OBJECTIVES: To report a case series of Intraoperative Blood Salvage (IOS) in surgeries during the treatment for Slipped Capital Femoral Epiphysis (SCFE) with controlled dislocation of the hip, identifying its efficacy, complications, and the profile of patients with SCFE. METHODS: Descriptive study reporting a case series, comprising patients seen between January 2016 and March 2018, diagnosed with SCFE, and treated with controlled surgical dislocation of the hip using IOS. RESULTS: Sample comprised of 15 patients, with a mean age of 13.1 years. The most affected side was the left with 8 cases. None of the patients required allogeneic blood in the postoperative period. Mean pre- and postoperative hemoglobin were 13.2 and 11.2 g.dL-1, respectively, and mean hemoglobin difference was 1.8 g.dL-1. Mean pre- and postoperative hematocrit were 39.13% and 33.20%, respectively, and mean hematocrit difference was 5.52%. No intraoperative complications were observed. One patient presented vomiting and another one, wound infection in the postoperative period. CONCLUSION: IOS was an alternative blood salvage approach and prevented allogeneic blood transfusion, enabling reduction of potential complications.

En adolescentes que consultan por dolor de cadera o pelvis, es crucial una adecuada historia clínica para orientarnos sobre la etiología del dolor y comprender los mecanismos que lo generan. Es importante conocer y realizar un exhaustivo examen físico, con especial énfasis en la cadera, incluyendo pruebas específicas para diferentes patologías, además de comprender las indicaciones de los diferentes estudios de imágenes, para así lograr un correcto diagnóstico.Entre las causas más frecuentes de coxalgia en adolescentes debemos considerar la epifisiolisis, el pinzamiento femoroacetabular con o sin roturas del labrum, las lesiones avulsivas de la pelvis, la coxa saltans, entre otras. Aunque son poco frecuentes, patologías sistémicas como reumatológicas y oncológicas también deben ser descartadas en adolescentes. Un diagnóstico de certeza nos permitirá realizar una adecuada estrategia de tratamiento, a fin de lograr una rehabilitación precoz y evitar futuras complicaciones.
In adolescents presenting with hip or pelvis pain, an adequate medical history is crucial to guide the etiology and understand the mechanisms that generate it. It is important to know and carry out an exhaustive physical examination, with special attention to the hip, including specific tests for different pathologies, in addition to understand the indications of the different imaging studies, in order to achieve a correct diagnosis. Among the most frequent causes of hip pain in adolescents, we must rule out slipped capital femoral epiphysis, femoroacetabular impingement with or without labral tears, avulsion lesions of the pelvis, snapping hip, among others. Although rare, systemic pathologies such as rheumatologic and oncologic diseases must also be ruled out in adolescents. An accurate diagnosis will allow us to carry out an adequate treatment strategy, in order to achieve early rehabilitation and avoid future complications.

PURPOSE: This study investigated the association between chondrolabral damage and time to arthroscopic surgery for slipped capital femoral epiphysis (SCFE). METHODS: This was a descriptive retrospective study that enrolled patients with SCFE who underwent hip arthroscopy for femoral osteochondroplasty after SCFE fixation. SCFE type, time from SCFE symptom onset or slip fixation surgery to hip arthroscopy and intraarticular arthroscopic findings were recorded. Acetabular chondrolabral damage was evaluated according to the Konan and Outerbridge classification systems. Nested analysis of variance and the chi-squared test were used for statistical analyses. RESULTS: We analyzed 22 cases of SCFE in 17 patients (five bilateral). The mean age at the time of hip arthroscopy was 13.6 years-old (8-20), and mean time from SCFE fixation to arthroscopy was 25.1 months (3 weeks to 8 years). Labral frying was present in 20 cases, labral tears in 16 and acetabular chondral damage in 17. The most frequent lesion was type 3 (41%) (Konan classification). Two cases had a grade III and 1 had a grade II acetabular chondral lesion (Outerbridge classification). Positive associations were observed between time from SCFE to hip arthroscopy and hip intraarticular lesions evaluated using Konan (p = 0.004) and Outerbridge (p = 0.000) classification systems. There was no association between SCFE severity (chi-squared = 0.315), stability (chi-squared = 0.558) or temporality (chi-squared = 0.145) type and hip intraarticular lesions. CONCLUSION: A longer time from SCFE symptom onset and fixation to hip arthroscopy is associated with greater acetabular chondrolabral damage. LEVEL OF EVIDENCE: IV.
RESUMO
Slipped capital femoral epiphysiolysis (SCFE) may result in femoroacetabular impingement (FAI) of the hip in up to one third of the cases. Residual deformity of the cam-type, or "pistol-grip", is associated with chondrolabral injury, resulting in pain, functional disability, and early osteoarthritis. The arthroscopic treatment with osteochondroplasty proved to be beneficial in a selected case of FAI secondary to SCFE.

ABSTRACT: This report described pathological fracture of the femoral head (physeal dysplasia) in four male cats (three mixed breed and one Bengal), with an average age of 16 months, treated by an ostectomy of the femoral head and neck. Three cats were neutered and one entire. All presented with mild intermittent lameness in the pelvic limbs. Displacement of the femoral epiphysis and resorption of the femoral neck were present and excision of the femoral head and remaining neck was performed in all cases. Hstological examination showed mild foci of compaction and trabecular fibrosis with deposition of fibrous connective tissue, permeated by granulation tissues, consistent with the original diagosis. Limb function improved in all patients from 2 to 4 weeks postoperatively. Diagnosis of physeal dysplasia is challenging and treatment is different from acute traumatic fractures. Femoral head and neck excision was considered a good alternative in these patients.
RESUMO: Este trabalho descreve a fratura patológica da cabeça do femur (displasia fiseal) em quatro machos (três raças mistas e um Bengal), com idade média de 16 meses, que foram tratados com ostectomia da cabeça e colo femorais. Três gatos eram castrados e um inteiro. Todos apresentaram leve claudicação intermitente nos membros pélvicos. O deslocamento da epífise femoral e a reabsorção do colo femoral estavam presentes, a excisão da cabeça e colo femoral foi realizada em todos os casos. O exame histológico mostrou focos de compacteção e fibrose trabecular com deposição de tecido conjuntivo fibroso, permeado por tecidos de granulação, consistentes com o suposto diagnóstico. A função dos membros melhorou em todos os paciente entre dois a quatro semanas pós-operatório. O diagnóstico da displasia fiseal pe desafiador e o tratamento é diferente das fraturas traumáticas agudas. A excisão de cabeça e colo femoral é considerada uma boa alternativa nesses pacientes.

Objectives To measure the mean value of the Southwick angle using two different methods, the manual (1) and digital (2) methods, and to establish a normality value. Methods A primarily descriptive study with 100 children and adolescents. Individuals with orthopedic complaints regarding the hips and/or knees or gait alterations were excluded. For each patient, an X-ray was performed on the lateral incidence of Lowenstein, totaling 100 radiographs and 200 hips. The Southwick angle was measured in two different ways by the same researcher: the conventional method (1), tracing the lines with pencils and measuring the angle with the use of a goniometer and negatoscope, and through the GNU Image Manipulation Program (GIMP) image editor (open source), version 2.7.0 (2), in which the lines were plotted and the angles of both hips were gauged on each radiograph. Later, we sought to evaluate the correlation between the two methods and to verify the mean Southwick angle by categorically correlating it by gender, age group and body mass index (BMI) in asymptomatic children and adolescents. All radiographs were authorized by the children and adolescents' parents/legal guardians. The study was approved by the ethics committee of the institutions in which the research was conducted. Results The mean of the Southwick angles obtained by the conventional method was of 8.7° (±2.0°), and, by the digital method, it was of 9.9° (±1.8°). The angle obtained by the two methods was statistically significant ( p < 0.001). The majority of the studied population (95%) had a body mass index (BMI) > 18.5, and the mean of the angles was within the previously established value (â¼ 10°). Conclusion For the first time, using a substantial sample size, a normal value for the Southwick angle measured in asymptomatic individuals was demonstrated. In addition, the image editor proved to be a reliable method to measuring the Southwick angle.
RESUMO
Resumen: La epifisiólisis femoral proximal o deslizamiento capital femoral es un trastorno de la cadera que se caracteriza por un desplazamiento de la epífisis sobre la metáfisis a través de la fisis (cartílago de crecimiento), quedando la epífisis posterior e inferior. Es una entidad relativamente frecuente en atención primaria y prehospitalaria que genera dolor y limitación de cadera; sin embargo, por su sintomatología vaga es usualmente infradiagnosticada o es diagnosticada tardíamente generando consecuencias a largo plazo. Si se tienen en cuenta los factores de riesgo asociados a una adecuada exploración física y el uso imágenes diagnósticas se lograría hacer un diagnóstico oportuno y una disminución de la tasa de complicaciones.
Abstract: Proximal femoral epiphysiolysis or slipped capital femoral is a hip disorder characterized by a displacement of the epiphysis over the metaphysis through the physis (growth plate), leaving the epiphysis in a posterior and inferior position. It is a relatively frequent entity in primary and prehospital care that generates hip pain and limitation. However, due to its vague symptoms, it is usually underdiagnosed or diagnosed late, generating long-term consequences. If the risk factors associated to an adequate physical examination and the use of diagnostic images are taken into account, a timely diagnosis and a reduction in the rate of complications would be achieved.
Resumo: A epifisiólise proximal do fêmur ou escorregamento epifisário proximal do fêmur é um transtorno do quadril que é caracterizado por um deslocamento da epífise sobre a metáfise por meio da fise (placa de crescimento), ficando a epífise posterior e inferior. É uma entidade relativamente frequente em atenção primária e pré-hospitalar que gera dor e limitação do quadril; contudo, por sua sintomatologia vaga, é usualmente subdiagnosticada ou é diagnosticada tardiamente, o que leva a consequências em longo prazo. Se os fatores de risco associados com uma adequada exploração física e com o uso de imagens diagnósticas forem considerados, é possível realizar um diagnóstico oportuno e diminuir a taxa de complicações.

Abstract Objectives To measure the mean value of the Southwick angle using two different methods, the manual (1) and digital (2) methods, and to establish a normality value. Methods A primarily descriptive study with 100 children and adolescents. Individuals with orthopedic complaints regarding the hips and/or knees or gait alterations were excluded. For each patient, an X-ray was performed on the lateral incidence of Lowenstein, totaling 100 radiographs and 200 hips. The Southwick angle was measured in two different ways by the same researcher: the conventional method (1), tracing the lines with pencils and measuring the angle with the use of a goniometer and negatoscope, and through the GNU Image Manipulation Program (GIMP) image editor (open source), version 2.7.0 (2), in which the lines were plotted and the angles of both hips were gauged on each radiograph. Later, we sought to evaluate the correlation between the two methods and to verify the mean Southwick angle by categorically correlating it by gender, age group and body mass index (BMI) in asymptomatic children and adolescents. All radiographs were authorized by the children and adolescents' parents/legal guardians. The study was approved by the ethics committee of the institutions in which the research was conducted. Results The mean of the Southwick angles obtained by the conventional method was of 8.7º (±2.0º), and, by the digital method, it was of 9.9º (±1.8º). The angle obtained by the two methods was statistically significant (p < 0.001). The majority of the studied population (95%) had a body mass index (BMI) > 18.5, and the mean of the angles was within the previously established value (∼ 10º). Conclusion For the first time, using a substantial sample size, a normal value for the Southwick angle measured in asymptomatic individuals was demonstrated. In addition, the image editor proved to be a reliable method to measuring the Southwick angle.
Resumo Objetivos Medir o valor médio do ângulo de Southwick utilizando dois métodos diferentes, manual (1) e digital (2), e estabelecer um valor de normalidade. Métodos Estudo primariamente descritivo, realizado com 100 crianças e adolescentes. Foram excluídos indivíduos que apresentavam queixa ortopédica nos quadris e/ou joelhos, ou alterações de marcha. Para cada paciente, foi realizada uma radiografia na incidência lateral de Lowenstein, totalizando 100 radiografias e 200 quadris. O ângulo de Southwick foi medido de duas formas pelo mesmo pesquisador: pelo método convencional (1), traçando-se as retas com lápis e medindo o ângulo com o uso de goniômetro e negatoscópio, e por meio do editor de imagem GNU Image Manipulation Program (GIMP; código aberto), versão 2.7.0 (2), no qual foram traçadas as linhas e aferidos os ângulos de ambos os quadris em cada radiografia. Posteriormente, buscou-se avaliar a correlação entre os dois métodos e verificar o ângulo médio de Southwick correlacionando-o categoricamente por gênero, faixa etária e índice de massa corpórea (IMC) em adolescentes e crianças assintomáticos. Todas as radiografias foram autorizadas pelos responsáveis. O estudo foi aprovado pelo comitê de ética das instituições em que a pesquisa foi realizada. Resultados A média do ângulo de Southwick obtida pelo método convencional foi de 8,7º (±2,0º), e pelo método digital, foi de 9,9º (±1,8º). O ângulo obtido pelas duas formas teve significância estatística (p < 0,001). A maioria da população estudada (95%) tinha índice de massa corpórea (IMC) > 18,5, e a média dos ângulos esteve dentro do valor previamente estabelecido como normal (∼ 10º). Conclusão Demonstrou-se, pela primeira vez, utilizando uma amostra substanciosa, um valor normal do ângulo de Southwick medido em indivíduos assintomáticos. Além disso, o editor de imagem mostrou ser um método confiável para mensuração do ângulo de Southwick.

OBJECTIVE: To prospectively characterize pain locations in slipped capital femoral epiphysis (SCFE) and evaluate pain locations as predictors of a delay in diagnosis. STUDY DESIGN: This was an institutional review board approved prospective study of 110 children who underwent surgery for SCFE at a tertiary children's hospital between 2009 and 2015. Standardized pain diagrams were completed by 107 children. Pain zones were designated via a composite diagram. Hips without hip pain were categorized as atypical; hips with hip pain were typical. RESULTS: In total, 122 hips were eligible for pain zone analysis. Seventy hips (57.4%) had hip pain. Atypical pain was present in 52 hips (42.6%), which included groin pain in 17 hips (13.9%), thigh/leg pain in 43 (35.2%), knee pain in 32 (26.2%), and posterolateral pain of the hip and leg in 13 (10.7%). A combination of pain zones was present in 48 hips (39.3%). Forty-nine percent of patients had more than 1 visit until diagnosis. The three most common pain locations for typical hips were hip, hip/thigh, and hip/knee pain (77.2% of typical hips). The 3 most common pain locations for atypical hips were isolated thigh, knee, and groin (65.4% of atypical hips). The least common pain presentations had a longer duration of symptoms (P = .04) and more healthcare visits before diagnosis (P = .04). CONCLUSIONS: A combination of pain locations is common in SCFE. Less frequent pain presentations may delay diagnosis. Delays in diagnosis continue despite education efforts.
