After classification of posterior hip dislocation by Thompson and Epstein, some treatment guide lines became proposed upon each types. However the most importance in treatment of posterior hip dislocation is prevention of 2 major complications, avascular necrosis of femoral head and post-traumatic arthritis. Authors experienced 16 cases of posterior htp dislocalion from Jan, 1988 to Dec. 1992. We analysed results of 16 cases which were available for minimum 1 year follow-up(Type I : 4 cases, Type II : 5 cases, Type IV cases, Type V : 3 cases).

The summary of our clinical experience were as follows;

1. Reverse Stimson method was very useful method in reduction of posterior dislocated hip.

2. Reasons for surgery were unconcentric reduction with intraarticular fragment, large acetabular fragment with instability and joint incongruity.

3. The incidence of osteoarthritis was high(56%) and there was no differences in its prevalance and severity according to each type of Epstein classification.
