Avascular necrosis of the acetabulum is a complication of an fragments. The extensile exposures such as the triradiate or extended iliofemoral acetabular fracture that can be attributable to both the provocative traumatic event and to a surgical exposure that is undertaken as part of an open reduction and internal fixation. In the former instance, devitalized fragments of bone can arise as free or impacted osseous or osteochondral segments. Surgically induced avascularity follows excessive stripping of soft tissue pedicles from bony or the application of two exposures for the inner and outer pelvic walls are particularly likely to culminate in devitalization of bone. Ironically, an associated fracture with notable comminution and displacement that further jeopardizes the osseous blood supply is the one in which an extensile exposure is likely to be used.¹
