Posterior approaches to the acetabulum.

Posterior approaches, particularly the Kocher-Langenbeck approach, remain the workhorses in the treatment of acetabular fractures. Various modifications have been developed, each offering specific advantages depending on surgical requirements. The modified Gibson approach, for example, is suggested to provide enhanced visualization of the superior acetabulum, although recent cadaveric studies have not consistently substantiated this benefit. The Ganz approach, which involves bigastric trochanteric osteotomy with safe surgical hip dislocation, is particularly advantageous for managing complex and comminuted posterior acetabular fractures, as it enables a 360° view of the acetabulum and femoral head. Overall, posterior approaches are associated with low rates of complications, with heterotopic ossification being the most prevalent. The choice of surgical approach and patient positioning should be guided by the surgeon's preference and expertise, tailored to the specific fracture pattern and patient characteristics.
