Abstract:
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 Ⅱ A stage,12 hips Ⅱ B,8 hips Ⅱ c,7 hips Ⅲ A.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-stagefemoral head necrosis with minimally invasive,rotary cutting pressure-relief,impacted graft,and tantalum rod supporting had a good short-term effects.
