Abstract:
Morcellized bone grafting was performed to significant acetabular deficiency in 35 hips of 29 patients in cementless total hip arthroplasty (THA). Bridging trabeculation across the graft-host interface, remodeling of the graft, and trabecular reorientation were observed at 4 weeks, 3.7 months, and 10.7 months postoperatively, respectively. These remodeling processes were observed in all cases. Morcellized bone grafting for acetabular deficiency in cementless THA stock, which is necessary to make the cup stable, revealed encouraging early trabecular reorientation and recovery of acetabular bone even in cases in which structural bone grafting is needed.
