Chipped allograft bone tissue has been used for bone loss around prosthetic stems in revision hip arthroplasty. The purpose of this study was to investigate the consolidation of the grafted allograft bone around the stem. The graft was judged to be consolidated when the bone trabecular pattern appeared around the stem radiographically. Six cases were investigated. In all cases bone consolidation was observed after 16 to 30 months (average: 21.7 months). No significant loosening or sinking was observed. This study showed the use of an allograft for bone loss around prosthetic stems is useful in order to cover the bone loss or defect in revision arthroplasty of hip joints.
