Open reduction and internal fixation alone versus open reduction and internal fixation plus total hip arthroplasty for displaced acetabular fractures in patients older than 60 years: A prospective clinical trial

•The first prospective clinical trial to our knowledge, comparing ORIF versus ORIF + THA for geriatric acetabular fractures.•ORIF + THA decreased the absolute risk of reoperation by 28% (95% CI, 13% to 44%, p < 0.01) compared to only ORIF treatment.•We did not observe differences in patient satisfaction and other validated outcome measures between the treatment groups.•Our results confirm that a combined ORIF + THA strategy can be safely performed in these challenging injuries.
