RADIOLOGICAL RESULTS OF SEVERE SCFE TREATMENT AT IOT-FMUSP FROM 2012 TO 2018.

Objective: To assess the complications in patients with severe slipped capital femoral epiphysis treated with the Dunn or modified Dunn procedure from 2012 to 2018 at the Institute of Orthopedics and Traumatology, Medical School, Universidade de São Paulo. Methods: Analysis of medical records, preoperative and postoperative radiographs with at least one year of radiographic follow-up of patients with severe slipped capital femoral epiphysis. Results: We reviewed the complications in 19 operated cases from 2012 to 2018, out of which 36.8% had osteonecrosis of the femoral head, one patient had chondrolysis, and another had postoperative infection. Conclusion: The osteonecrosis rate observed in this series of cases is similar to that described in other orthopedic facilities. We assessed factors that could potentially influence this outcome, including other characteristics of the patient (obesity, endocrine diseases, and history of sports activities) and of the health system. Level of Evidence III, Restropective Case Series.

Objetivo: Avaliar as complicações apresentadas nos pacientes com epifisiolistese grave tratados por meio do procedimento de Dunn ou Dunn Modificado entre 2012 e 2018 no IOT-FMUSP. Métodos: Análise de prontuários, radiografias pré-operatórias e radiografias pós-operatórias com pelo menos 1 ano de seguimento radiográfico dos pacientes com epifisiolistese grave. Resultados: Analisou-se a presença de complicações em 19 casos operados de 2012 a 2018. Desses pacientes, 36,8% apresentaram osteonecrose da cabeça femoral, oi observada condrólise em 1 paciente e infecção pós-operatória em 1 paciente. Conclusão: A taxa de osteonecrose observada nesta série de casos está próxima à descrita em outros serviços. Alguns fatores que potencialmente influenciariam neste desfecho poderiam ter sido avaliados, como outras características do paciente (obesidade, doenças endócrinas e atividade esportiva) e do sistema de saúde. Nível de Evidência III, Série Retrospectiva de Casos .

Deslizamientos epifisarios femorales proximales >30º: Procedimiento de Dunn modificado Evaluación anatómica y funcional en una cohorte retrospectiva

Introducción: La deformidad residual resultante de un deslizamiento epifisario femoral proximal moderado o grave conduce a osteoartritis prematura debida al choque femoroacetabular. Los objetivos del trabajo fueron evaluar la mejoría de la anatomía del fémur proximal y evaluar la función de la cadera en pacientes con deslizamiento epifisario femoral proximal >30 grados tratados con el procedimiento de Dunn modificado, a corto plazo. Materiales y Métodos: Cohorte retrospectiva de pacientes con deslizamiento epifisario femoral proximal >30 grados, tratados con luxación controlada de cadera y el procedimiento de Dunn modificado. Se evaluaron mediciones clínicas y radiológicas preoperatorias y posoperatorias, hallazgos intraoperatorios y funcionalidad con los puntajes de Harris y de DAubigne-Postel. Resultados: Trece casos, mediana de edad 12 años y mediana de seguimiento 14 meses. El ángulo de deslizamiento de Southwick preoperatorio (75 grados, RI 67-85) y posoperatorio (10 grados, RI 5-17) mostró una disminución estadísticamente significativa (p <0,001). El offset radio cabeza-cuello preoperatorio (-0,13) versus el posoperatorio (0,12) obtuvo una mejoría significativa (p 0,002). El 69,2% de los pacientes presentó daño de alguna estructura intraarticular. Los puntajes promedio de funcionalidad fueron 14,6 (muy buena mejoría) y 83,4 (bueno). Complicaciones: necrosis avascular 15,3% y condrólisis 15,3%. Conclusiones: Esta técnica restaura la anatomía del fémur proximal y la funcionalidad de la cadera a corto plazo. Aunque no disponemos de resultados a largo plazo, al menos en teoría, serían buenos. Sin embargo, la luxación controlada con Dunn modificado no está exenta de complicaciones y el riesgo de necrosis avascular y condrólisis persiste.(AU)

Background: The residual deformity resulting from a moderate and/or severe proximal femoral epiphysis slipping (SCFE) leads to premature osteoarthritis due to impingement. The objectives were to assess improvement in the anatomy of the proximal femur and to evaluate hip function in patients with SCFE >30° treated with the modified Dunn procedure. Methods: A retrospective cohort of patients with SCFE >30° treated with hip dislocation control and modified Dunn procedure. Preoperative and postoperative clinical and radiographic measurements, intra-operative findings and functionality using Harris and DAubigne & Postel scores were evaluated. Results: Thirteen cases, median age 12 years, median follow-up 14 months. Southwick slip angle showed a statistically significant decrease (preoperative: 75, IR 67-85; postoperative: 10, IR 5-17) (p <0.001). The head-neck offset radius obtained a significant improvement (preoperative -0.13; postoperative: 0.12) (p 0.002). The 69.2% of patients presented intraarticular damage. The average scores for functionality were 14.6 (excellent improvement) and 83.4 (good). Complications: avascular necrosis 15.3% and chondrolysis 15.3%. Conclusions: This technique restores the anatomy of the proximal femur and hip functionality in the short term. Although we do not have long-term results, at least in theory they would be good. However, the dislocation controlled with modified Dunn procedure is not free of complications and the risk of avascular necrosis and chondrolysis persists.(AU)
