To determine if initial treatment affects the outcome of total hip arthroplasty (THA) after acetabular fracture.

49 patients (49 hips) initially treated non-operatively followed some months later by THA in conjunction with acetabular reconstruction (Group 1) and 29 patients (29 hips) who had undergone THA after a previous osteosynthesis (Group 2) were assessed. The mean follow-up was 11.7 (range 5–23) years.

3 acetabular components were revised for aseptic loosening in Group 1 and 2 in Group 2. The survival rate for cup loosening at 16 years was 90.6% (95% confidence interval [CI], 78.1–100) for Group 1 and 94.1% (95% CI, 86.5–100) for Group 2 (p = 0.76). There were 2 sciatic palsies in Group 2 after osteosynthesis. The mean preoperative clinical score and postoperative range of mobility were better in Group 1. There were more heterotopic ossifications in Group 2.

Despite the good results found in both groups, THA after previous osteosynthesis for acetabular fractures had more complications than a primary THA in conjunction with acetabular reconstruction.
