title: Therapeutic effect of minimally invasive decompression combined with impaction bone grafting on osteonecrosis of the femoral head.
abstract: The aim of this study was to observe the therapeutic effect of minimally invasive decompression combined with impaction bone grafting on osteonecrosis of the femoral head. A total of 67 patients underwent minimally invasive lightbulb decompression combined with impaction bone grafting. The therapeutic effect was evaluated according to Harris scores, and fluoroscopic and magnetic resolution imaging results at different time points. The Harris score was significantly increased after operation. The fineness rate was 85.4%. Postoperative disease progression was found in nine patients with the progression rate of 14.63%. The average necrotic area percentage was noticeably reduced 6 months, 1 year, and 2 years after operation. The one-year postoperative percentage showed a significant difference compared with the preoperative one. Minimally invasive lightbulb decompression combined with impaction bone grafting can achieve a satisfactory curative effect on ONFH. This method has the advantages of small trauma, thorough decompression, and good bone implantation.
