[Late results of the treatment of the slipped upper femoral epiphysis (26 cases with follow-up study over 10 years)].

Abstract

In our series, osteoarthrosic hips are seen in 60 per cent cases. Radiographic degradation was constant after 25 evolution years. The hips with less than 40 degrees slipping after treatment have the best results and no arthrosis. Thus, in situ fixation is recommended for slipping inferior to 40 degrees. If displacement is greater than 40 degrees, Dunn's operation or trial orthopedic reduction to obtain a reduction of slipping is preferred, according to the character (chronic or acute) of the slip.
