Assessment and classification of bone stock deficiency in revision total hip arthroplasty.
It is critical for appropriate treatment choices in revision total hip arthroplasty that bone stock deficiency be assessed and classified. Acetabular and femoral defects must be separately assessed, although a combined assessment is needed at the time of surgery to select the appropriate match of components for a given patient. Classification systems help surgeons predict defects and determine reconstruction planning prior to surgery. This article presents the senior author's classification of acetabular and femoral defects for revision total hip arthroplasty.
