摘　　要：目的 应用金属重建钽棒植入治疗股骨头早期缺血性坏死（Steinberg Ⅰ～Ⅱ期）,探讨股骨头早期缺血性坏死的微创治疗方法.方法 24例患者（Steinberg Ⅰ～Ⅱ期）采用C型臂X线机透视下在股骨大转子下经股骨颈钻孔至股骨头缺血坏死区,先对硬化区髓芯减压,再行钽棒植入至软骨下骨约0.5 cm处,通过手术前后Harris评分进行比较.结果 经过随访9（2～12）个月,术前疼痛及功能受限均明显缓解.术后优良率为83%.患者MRJ表现稳定,无缺血坏死加重表现.结论 髓芯减压可以明显降低股骨头硬化区内压力,钽棒植入提供了股骨头负重区软骨下骨结构性支撑.该方法具有减压、结构性支撑、微创的特点,值得临床推广使用.Objective To investigate the effeit of Reconstruction of tantalum metal rod implantation in the treatment of early ischemic necrosis of femoral head（ Steinberg Ⅰ～Ⅱ period） ,to explore the early femoral head ischemic necrosis of minimally invasive treatme（n）t. Method 24 patients（ Steinberg Ⅰ～Ⅱ period） using C-arm fluoroscopy machine,under the greater trochanter through the neck hole to avascular necrosis zone,the first zone of the medullary sclerosis core decompression, re-implantation of tantalum rod to the subchondral bone is about 0.5 cm, through the Harris score before and after surgery for comparison. Results After follow-up 9（2 ～ 12） months,preoperative pain and function were significantly limited nuitigation. The excellent rate was 83% after opertion. MRI manifestations in patients with stable,non-ischemic necrosis increased performance. Conclusion Core decompression can significantly reduce the pressure on the femoral head hardening region, tantalum rod weight-bearing area of femoral head implant provides a structural support for subchondral bone. This method has the characteristics decompression,structural support,minimally invasive,it is worth for clinical use.
