Acetabulum Posterior Wall Fracture Failed Fixation
摘要
Failure of operative treatment of acetabular posterior wall fractures may have a variety of aetiologies, with the most common being technical errors. Examples include intra-articular lag screw penetration, not recognizing fracture patterns that require either a spring or rim plate and inadequate use of bone graft for structural support in cases with an associated marginal impaction injury. This chapter illustrates an example of fixation failure of a posterior wall acetabular fracture secondary to buttress plate misplacement.
