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.
髋臼缘骨块的边缘嵌顿通常可通过特定于损伤性质的骨折面触及。然而，罕见情况下，这些已有的骨折面无法触及嵌顿的髋臼缘骨块或游离的骨软骨碎片。因此，必须考虑其他方法来触及这些关节骨块，以确保充分复位。我们描述了一种后柱截骨术来触及嵌顿的骨块和髋臼缘骨块的边缘嵌顿，从而实现关节的同心复位。
