title: Posterior Wall Osteotomy of the Acetabulum to Access Incarcerated Marginal Impaction.
abstract: Marginal impaction of the acetabulum is typically accessible through fracture planes specific to the nature of the injury. Infrequently, however, incarcerated marginal impaction or free osteochondral fragments are not accessible through these existing fracture planes. As such, alternative methods to access these articular pieces must be considered to ensure adequate reduction. We describe an osteotomy of the posterior wall to access incarcerated fragments and marginal impaction of the acetabulum, enabling concentric articular reduction.
