Abstract

At an average of 6.3 years after surgery, we evaluated midterm results of uncemented acetabular reconstruction in 31 hips with posttraumatic arthritis that developed after acetabular fracture. Patients were categorized by previous fracture treatments (open-reduction group and conservative-treatment group) and fracture patterns (simple group and complex group). Surgery duration and blood loss were greater in the open-reduction and complex groups than in the conservative-treatment and simple groups (P < .05). The mean Harris Hip Score increased from 49 before surgery to 89 after surgery. Survival with revision or radiographic acetabular loosening as an end point was 100%. Fracture treatments and patterns were associated with increased surgery duration and increased blood loss. Open reduction and internal fixation of a fracture favor anatomical restoration of the hip's rotational center.

Materials

Between January 2000 and December 2003, 34 uncemented acetabular reconstructions were performed in 34 patients for posttraumatic arthritis after acetabular fractures. Of the 34 patients, 3 cases were lost to follow-up because of changed contact information; 31 patients underwent complete clinical and radiographic follow-up for an average of 6.3 years (range, 3.1-8.4 years).

There were 22 men and 9 women. The patients' average age was 51 ± 12 years (range, 27-74 years) at the time of

Clinical Results and Complications

The 31 patients have been followed up for an average of 6.3 years; no infection occurred, and no revision was needed. Two patients died, 1 in a traffic accident and 1 because of heart disease; but follow-up data for a minimum of 3.1 years were available for these 2 patients.

In the open-reduction and conservative-treatment groups, the respective averages for duration of surgery, intraoperative blood loss, and amount of blood transfused were 138 ± 29 and 98 ± 16 minutes (P < .001), 726 ± 288 and

Discussion

In posttraumatic arthritis after an acetabular fracture, the relationship between fracture treatments and THA results is still controversial. Study findings by Romness and Lewallen [4], Boardman and Charnley [18], and Catalano and Born [19] led us to the following conclusions: THA results are better in patients whose acetabular fractures were treated by ORIF than those in patients whose fractures were treated conservatively. However, after 5.3 years of follow-up of 30 uncemented THAs in
