Objective To investigate new methods of osteonecrosis of femoral head (ONFH) with retrospective analysis of the clinical cases with technique of rotary cutting pressure-relief, impacted graft, and tantalum rod supporting treatment of early-stage femoral head necrosis. Methods From June 2010 to June 2014, 32 cases (38 hips, 23 males and 9 females) with ONFH were treated with technique of rotary cutting pressure-relief, impacted graft, and tantalum rod supporting, with the mean age of 24~52 (36.2±3.8) years old. According to the Association Research Circulation Osseous (ARCO) classification, there were 11 hips on ⅡA stage, 12 hips ⅡB, 8 hips ⅡC, 7 hips ⅢA. The averaged Harris score of all cases was 65~81 (72.5±5.8) points. All cases were cured with minimally invasive technique, rotary cutter pressure-relief in femoral head, thoroughly remove sequestrum and implant allogeneic bone. Postoperative patients laid in bed for 1 month, after 1 month hold crutch gradually began to functional training. Postoperative 1 month, X ray film was reviewed every 3 months. According to the clinical symptoms, imaging findings, Harris scoring system was graded to evaluate the effectiveness. Results All the cases were followed up for average of 12~32 (20.2 ±2.6) months, 31 hips Kept hips succeed, hips pain; lame line symptoms were reduced or disappeared; x-ray showed femoral head necrosis area formed new bone, Harris scoring was upgraded to 75~95 (87.7±6.4) points; and seven hips failed with operation of total hip arthroplasty. The overall good rate was promoted from 26.3% to 84.2%. Conclusions The technique treating for early-stage femoral head necrosis with minimally invasive, rotary cutting pressure-relief, impacted graft, and tantalum rod supporting had a good short-term effects.
