[Superior femoral epiphysiolysis. Long term results].

Analysis of the long-term outcome of slipped capital femoral epiphysis convincingly demonstrates that early diagnosis is essential. Chronic slipping with significant displacement are associated with a high rate of adverse outcomes including necrosis, chondrolysis, and early osteoarthritis. Orthopedic reduction increases the risk of complications. Inadequate reduction is associated with poor hip function and a high risk of early osteoarthritis. Improvements in overall long-term outcome could be achieved only by reducing the number of chronic forms with major displacement, since prognosis is generally favorable in acute forms and chronic forms with minor displacement.
