Total hip arthroplasty for the treatment of osteoarthritis secondary to acetabular fractures treated by open reduction and internal fixation

Acetabular fractures are associated with damage to the femoral head, acetabular cartilage and labrum and possible disruption of the femoral head blood supply. Treatment aims to provide the best opportunity for restoration of joint function and to prevent long-term complications. Surgical intervention, in the form of open reduction and internal fixation (ORIF), is often required. Where post-traumatic osteoarthritis develops after ORIF, total hip arthroplasty (THA) is often required. Our aim here has been to identify and highlight our experience with the key technical points associated with successful outcomes for THA in this setting.
A single-centre retrospective review of patients with acetabular fractures treated with ORIF and subsequent THA over a 4-year period was undertaken. Demographics, mechanism of injury, complications, interval time between surgeries, intra-operative outcomes and post-operative outcomes were recorded. Particular emphasis is made to describe standard pre-operative and intra-operative protocols.
Twenty-five patients were identified, with a mean age of 51.1 years at time of first ORIF. 60% presented following RTA. 80% of fractures involved the posterior wall or column. Meantime to eventual THA was 2.3 years. Mean THA duration was 1.52 h, with mean intra-operative blood loss and length of stay of 585 ml and 5 days, respectively. 24% required intra-operative removal of metal, with only one patient suffering a complication post-THA.
Acceptable post-operative outcomes were demonstrated throughout the case series. In describing the pre-operative work up, intra-operative findings and intra-operative and post-operative complications encountered, common important technical points associated with a successful surgical strategy are described. Furthermore, potential pitfalls that may be encountered can be anticipated.
