Management of Acetabular Fractures with Total Hip Replacement: A Narrative Literature Review.

Abstract

Open reduction and internal fixation (ORIF) is widely regarded as the primary treatment for acetabular fractures, but limitations arise in complex cases, leading to non-anatomical reductions and increased risk of post-traumatic osteoarthritis. Given the high incidence of secondary arthritis (12-57%) following ORIF, total hip arthroplasty (THA) is often necessitated, particularly in scenarios unsuitable for ORIF, such as extensive comminution or combined femoral head and neck fractures. The surgical landscape has shifted from a traditional "fix or replace" to a more integrated "fix and replace" approach, especially beneficial in managing elderly patients with osteoporotic bones. THA is applied across various timelines, including acute (0-3 weeks), delayed (3 weeks to 3 months), and late (beyond 3 months), each presenting distinct challenges and requiring specific strategies to optimize outcomes. The importance of precise bone defect classifications and the role of dual mobility cups in reducing dislocation risks are highlighted, alongside the use of modern surgical and fixation techniques to improve stability and patient outcomes. Enhanced recovery protocols and meticulous postoperative management are critical to addressing complications, such as infections and hardware interference, tailoring treatment approaches to each patient's needs, and advancing care for complex acetabular fractures.
