Objective: To retrospectively evaluate the open reduction internal fixation and total hip arthroplasty directions, results and complications associated with internal fixation in managing these fractures. Methods: In 8 years at 4 centers, 61 patients with associated acetabular fractures (Letournel classification) were treated. The patients were divided into two groups. The total hip arthoplasty (THA) group consisted of 30 patients, while the open reduction internal fixation group had 31 patients. The average age of the patients was 74.7 years. The following parameters were compared: the duration of surgery and hospitalization, the international unit of red blood cell concentrate transfusion, the time for the verticalization of the patient, perioperative complications, Harris hip score, and the short form (12) health survey. The clinical and radiographic follow-up was performed at 1 month, 3 months, 6 months and 12 months and annually thereafter. Patients with post-traumatic osteoarthritis formed the third comparison group. P ≤ 0.05 was considered statistically significant according to the analytical Student's t-test. Results: The P < 0.05 in favor of the THA group was: surgical time, length of stay, number of the international unit of red blood cell concentrate transfusions, verticalization, quality of life and hip function, a reduction of perioperative complications and reinterventions. Conclusions: Our experience shows that the THA treatment for acetabular fractures in the elderly is to be preferred.
