Slipped capital femoral epiphysis (SCFE) is a common adolescent hip disorder. It is typically a posteromedial displacement of the epiphysis on the metaphysic. The goals of the treatment are directed toward stabilisation of the slip and preventing further progression of the slip, as well as minimizing the risk of avascular necrosis. A retrospective analysis of data was performed including the child’s sex, age, weight and height, type of SCFE, method of operation, kind of slip, slip severity and the subjective assessment of well-being. SCFE is classified into three types: acute, chronic, and acute on chronic. The degree of displacement of the epiphysis on the femoral neck was measured on plain radiographs. The slip angle was classified as mild (45°). Statistical analyses were performed by Cramer's-V and Spearman test. The aim of the study was to evaluate treatment outcomes and complications. The study included 29 children. Six patients had bilateral involvement, 23 patients had unilateral involvement. The average age at the time for the first slipped capital femoral epiphysis was 13.6 years (11-15 years) for the boys and 12.2 years (10-15 years). In the group of the children the slip angle was measured, there were 12 mild, nineteen moderate, and four severe slips. The operative options depended on the type and grade of the slip. Between 1975 and 1995, in situ fixation was carried out in 12 cases for mild and stable slips, in 13 cases for moderate slips. No postoperative osteonecrosis or osteoarthritis occurred during the average follow-up period of 17.7 years. When the grade was more than 30°-45°, intertrochanteric or subcapital osteotomy to correct the posterior slip and to stabilize the slipped epiphysis was considered in 10 cases. Osteonecrosis occurred in two cases. Our retrospective analysis, even though carried out on a limited number of cases, showed that (1) hips with severe slip at first control showed a higher degree of arthrosis;(2) slipping degree was proportional to the result obtained; (3) the presence of chondrolysis or epiphyseal necrosis are early signs for hip arthrosis; (4) the subjective assessment of clinical outcome was good.
