Abstract

The Posterior wall and column fracture of the acetabulum is clinically important because of its range of motion and weight bearing portion, and in majority cases, they accompany with posterior dislocation of the hip. When the fractures were not treateci well, they may give rise to disabling symptoms such as traumatic arthritis and avascular necrosis of the femoral head. So, accurate reduction is more important than other fractures. The purpose of this study is to know the clinical results and complications when reduced surgically the posterior wall fractures of acetabulum with posterior hip dislocation. Sixteen cases of posterior wall fracture of acetabulum with posterior hip dislocation were treated surgically in the presbyterian medical center during the period 1981 to 1995. The short summary of observations were following as; 1. According to Letoumels classification, simple posterior wall fracture was 10 cases, comminuted posterior wall fracture in 4 cases, and posterior wall and column in 2 cases, and relatively good clinical result was seen at the simple posterior wall fracture. 2. The complications were traumatic osteoarthritis in 4 cases(25%), and heterotopic ossification in 2 cases(12.5%). 3. The clinical result above Good was 14 cases(88%), the roentgenographic result above Good was 11 cases(69%), and they were correlations in each others(P<0.05).
