title: Dislocation of the proximal femoral epiphysis in acetabular fractures.
abstract: Acetabular fractures are often associated with dislocation of the proximal femoral epiphysis. The dislocation may be of three types, based on the type of fracture to which it is associated: anterior, central, posterior. In anterior and in central dislocation epiphyseal necrosis of the proximal femur has never been observed, while in posterior dislocation necrosis has been observed in 23% of cases. Diagnosis of posterior dislocation is of essential importance so that it may be reduced immediately, decreasing the risk of necrosis. The authors report a review of 192 fractures of the acetabulum to which dislocation of the femoral epiphysis was associated, treated between 1980 and 1996 at the IIIrd Division of the Rizzoli Orthopaedic Institute.
