Radiographs illustrate the case of a 36-year-old female patient who had rheumatoid arthritis (RA) in the right hip. a An AP view of the hip shows a Dorr C femoral bone combined with severe osteoporosis. Note the deep acetabulum and extremely widened femoral canal with very thin cortices. These parameters are limited by the use of most primary conventional prosthesis or hip resurfacing arthroplasty. b Total hip arthroplasty (featuring placement of a cementless porous acetabular component and a short Tri-Lock bone preservation stem, Tri-Lock, DePuy) was accompanied by acetabular reconstruction with an autologous bone graft. An AP X-ray taken after surgery revealed that the initial stability of the acetabular cup and stem was good. The radiolucent line between the acetabular wall and peripheries of the cup is bone grafting by autologous femoral head impaction. c Lateral view postoperatively
