Acetabular revision using ReadiGraft® BLX Putty and cortical/cancellous bone chips

Acetabular bone loss presents a challenge to the revision total hip arthroplasty surgeon. It is described a technique of stressing the acetabular bone intra-operatively to access for pelvic discontinuity and the use of allograft to fill the bone gap. Three radiographic criteria are assessed on the AP radiograph for pre-operative classification according to the Paprosky system. This paper describes the pre-operative assessment, the acetabular defect classification and the surgery to achieve a successful outcome.
