Abstract
During the ten years from 1986 to 1996, 19 traumatic dislocations and fracture-dislocations of the hip were treated at the Tamana Central Hospital. There were 17 cases of posterior dislocation and 2 cases of anterior dislocation, in patients aged from 16 to 72 years (average age 40.6 years). The posterior fracture-dislocations were classified according to Thompson and Epstein's classification. In these cases there were seven Type I lesions, one Type II lesion, two Type III lesions, three Type IV lesions and four Type V lesions. Patients were clinically evaluated according to the Japanese Orthopaedic Association's (JOA) hip score.
Six (Type I) cases were treated by closed reduction; thirteen, by closed reduction followed by open reduction. Traumatic arthritis was present in five: all of Type III, one of three Type IV, two of four Type V hips. Avascular necrosis was evident in three: one of two Type III, two of four Type V hips. The average JOA score for all hips was 92.2 points (range: 70-100 points) at the time of follow-up examination.
