Evaluation of total hip arthroplasty for management of acetabular fracture complications: A prospective cohort study

Objectives: Total hip arthroplasty (THA) has been recommended as an effective tool for restoring joint function. This study aimed to evaluate the functional and clinical outcomes of THA management of acetabular fracture late complications such as arthritis by both Harris-Hip Score (HHS) and Western Ontario McMaster Osteoarthritis Index (WOMAC) score, anticipate, and prevent the most common complications such as infection and dislocation. Methods: This prospective case series included 30 patients with THA to manage acetabular fracture complications such as arthritis. The study started in November 2021 and ended in September 2023. Inclusion criteria were patients with acetabular fractures with secondary arthritis (pre-existing osteoarthritis were excluded) aged 25- 70 and who had at least 1 year from fracture to arthroplasty. Exclusion criteria were patients with a history of previous infection. Results: Heterotopic ossification (HO) improved statistically significantly after using ketorolac at an 18-month follow-up compared to preoperatively. Using both the HHS and WOMAC scores, a statistically significant difference was found between pre-operative and post-operative functional outcomes for estimating HO development using radiographs. Conclusion: THA was safe and effective in managing late acetabular fracture complications. Ketorolac use showed promising results in prophylaxis against HO.
