Research discussion / Pelvic & acetabular
Fix, replace, or combine?
Weighing early operative burden against later reconstruction in geriatric acetabular fractures.
What the study found
Across 20 studies, this review compared open reduction and internal fixation (ORIF) with acute total hip arthroplasty, often combined with fixation as a combined hip procedure (CHP). Early function generally favoured arthroplasty-based treatment, while fixation alone carried a substantial risk of later reconstruction. Reported conversion to arthroplasty after ORIF ranged from 14% to 45% across studies; this is a range from different cohorts, not a pooled risk for an individual patient. Combined procedures also involved longer operations and greater blood loss.
A closer look
The largely non-randomised evidence is vulnerable to treatment-selection bias. Fracture complexity, frailty, bone quality and baseline mobility may influence both the operation selected and the result. Different follow-up periods and outcome definitions further limit comparisons. An association between fracture pattern and treatment choice is not proof that the chosen procedure is superior for that pattern.
For the course discussion
For a Traumaplasty discussion, the central trade-off is immediate operative burden versus the possibility of another major operation later. Compare the patient’s mobility goals and physiological reserve with the likelihood of durable fixation. The review supports an individual discussion, rather than a rule that age or fracture classification alone should determine treatment.

For an older patient with acetabular impaction, which findings would change your preference between fixation and a combined hip procedure—and which outcomes would matter most to that patient?
