ORIF linked to higher reoperation risk than acute THA/CHP in older patients with acetabular fractures
This systematic review and meta-analysis compared outcomes of open reduction internal fixation (ORIF) versus acute total hip arthroplasty or hemiarthroplasty (THA/CHP) in 949 patients aged 60 years and older with acetabular fractures. The primary outcome was not reported; secondary outcomes included reoperation, post traumatic osteoarthritis, dislocation, and Harris Hip Scores.
Reoperation was significantly more common after ORIF (RR 2.60; 95% CI 1.42 to 4.75; P = 0.002). Post traumatic osteoarthritis occurred in 34% of ORIF patients. Dislocation occurred in 8% of THA/CHP patients. Harris Hip Scores were higher in the arthroplasty group (mean difference -6.11; 95% CI -9.90 to -2.31; P = 0.002). Notably, ORIF patients were younger (mean difference -4.14 years; P < 0.01) and had lower American Society of Anesthesiologists scores (P = 0.02), suggesting potential selection bias.
The authors did not report specific limitations, but the observational nature of included studies and baseline differences between groups limit causal inference. For older patients with acetabular fractures, acute arthroplasty may reduce reoperation risk and improve functional outcomes, though dislocation risk is higher. Individualized surgical decision-making remains essential.
