Abstract
The purpose of this study was to evaluate the outcome of femoral impaction bone grafting with an allograft combined with hydroxyapatite (HA). Fifty-four consecutive femoral reconstructions that were performed with the use of frozen morselized allografts and HA were followed up retrospectively. The average follow-up period was 92 months. A femoral head and HA were mixed and used as allograft. The average Merle d'Aubigné clinical score improved from 8.9 preoperatively to 13.1 points postoperatively. Stem subsidence was seen in 26 hips; however, it was not progressive after 1 year postoperatively. Cortical repair was detected at an average of 7 months postoperatively. Impaction bone grafting with an allograft combined with HA provided favorable results, with bone remodeling and less subsidence.
