Slipped capital femoral epiphysis

Abstract

Posterior slipping of the upper (capital) femoral epiphysis (SUFE) is the most common cause of hip disability in early adolescence, until the growth plate closes. A number of factors contribute to a relative weakening of the growth plate and its surrounding fibrocartilaginous perichondrial ring, culminating in a shearing displacement through the zone of hypertrophic cartilage. The resultant symptoms and loss of function may be trivial or profound. Treatment is directed at preventing progressive slippage, minimizing deformity, and avoiding the major complications of avascular necrosis (AVN) and chondrolysis. Incidence: The incidence of SUFE is 2-3 per 100,000 children and adolescents [1] and is dependent upon race, gender, and geographical region. © Springer-Verlag London Limited 2010.
