Outcomes of acetabular fractures in the elderly: a five year retrospective study of twenty seven patients with primary total hip replacement

Open reduction and internal fixation (ORIF) in osteoporotic acetabular fractures is quite difficult with high risk of implant failure. Total hip arthroplasty (THA) may be an effective option for treating acetabular fractures in appropriately selected patients, with immediate full weightbearing. The aim of the study was to evaluate the functional outcomes of primary THA for acetabular fractures in elderly patients.
Between 2010 and 2015, 27 elderly patients operated for acetabular fractures by primary THA were included. The surgical technique associated plate stabilization of both acetabular columns with THA using an acetabular reinforcement cross-plate. Mean age was 68.5 years (57–84) and mean ASA was 2 (1–3). The mean follow-up was four years.
The mean Harris score was 70.4 ± 23 (24–90), and the mean Postel-Merle Aubigné (PMA) score was 14.3 ± 4 (7–18). For 17 patients with rank of pre-operative Devane 4, the post-operative rank was unchanged (p < 0.05). Twenty patients (74%) were satisfied by the surgical treatment. Twenty post-operative complications (74%) were found. Two patients died during follow-up (7%).
Primary THA for acetabular fracture in the elderly population might be a good therapeutic option that allows return to the previous daily life activity. Three patients (11%) became bedridden, and four patient’s skiers (15%) returned to skiing. However, this surgery is difficult and selection of elderly patients, i.e., with acetabular fractures who are expected to get a poor result with ORIF, i.e., fracture patterns with posterior wall lesion and marginal impaction, for primary THA in an experienced centre provides satisfactory clinical results.
