THA Revision for a Paprosky 3B Acetabular Defect
This is a 77 year old female who had a cemented hip replacement 30 years ago in Europe. She presented with gradual onset pain and was unable to bear weight on her right hip. She previously had her left hip revised by another surgeon. X-rays demonstrated a loose acetabular component and an “up and in” Paprosky 3B acetabular defect.
The patient underwent right hip revision surgery. The acetabulum was reconstructed using porous tantalum augments and a highly porous tantalum revision shell. An extended trochanteric osteotomy (ETO) was used to remove the femoral stem and cement, and a modular tapered titanium stem was used to reconstruct the femur.
