Geriatric patients are the fastest-growing group of people who have acetabular fractures (AFs). On a broad population basis, the aim of this study was to compare the risk of a secondary total hip arthroplasty (THA) in older patients with a prior AF open reduction internal fixation (ORIF) to younger patients with an AF ORIF.

All adult patients with an AF ORIF and a minimum of two years follow-up were classified and included using administrative healthcare data. A Cox proportional hazards model with patient risk factors was used to investigate the risk of THA. Surgical complications and all-cause mortality were among the secondary outcomes.

Results:
--A total of 1,725 patients had an AF ORIF; 1,452 aged less than 60 years (“younger”) and 273 aged more than 60 years (“older”).

--The mean (SD) follow-up time for all patients was 6.9 years. In older patients, 19.4% went on to receive a secondary THA with a median time to event of 3.9 years, compared to 12.9% in the younger patient cohort with a median time of 6.9 years.

--As expected, older patients had a higher 90-day mortality rate compared to younger patients (7.7% vs 0.7%, respectively; HR 9.2).

Finally, relative to younger patients with an AF ORIF, older patients with an AF ORIF have a slightly higher chance of a secondary THA.
