Fourteen cases with dislocated fractures of the hip joint were treated surgically. They were classiffied into type II (3 cases), III (3 cases), IV (3 cases) and type V (5 cases) according to the Thompson and Epstein classification.
All cases achieved bone union. There were in 3 cases with osteonecrosis of the femoral head. Using the criteria for assessment described by Thompson and Epstein, excellent results were achieved in 5 cases, good in 7, and fair in 2.
Anatomical reduction with internal fixation following earlier reduction of the dislocation are important for good treatment results.
