多孔髓芯减压支撑植骨并关节囊开窗治疗早期股骨头缺血性坏死

目的:探讨多孔髓芯减压支撑植骨并关节囊开窗治疗早期股骨头缺血性坏死的疗效。方法:应用股骨头多孔髓芯减压支撑植骨并关节囊开窗治疗早期股骨头缺血性坏死患者46例(52髋)。行患髋多孔髓芯减压支撑植骨并关节囊开窗术,临床采用Harris评分系统评估,并分期X线检查。结果:经平均随访18个月关节疼痛明显缓解,功能明显改善。影像学表现:股骨头坏死区域有不同程度缩小,有部分股骨头坏死发展缓慢,术前平均HARRS评分41.2,术后平均88.1。结论:多孔髓芯减压支撑植骨并关节囊开窗可有效进行骨内及关节内减压,改善内环境,减轻疼痛,阻止病情发展或延缓病情发展,该方法简单有效,花费低,适合早期股骨头缺血性坏死的患者。

Objective：To Study the technique of medullary core decompression and im- plantation supporting hone and the capsular cutting window for the patients with avaseu- lar necrosis of femoral head at early stage by evaluate the clinical effect. Methods： Since October 2005 to June 2011 , A retrospective study was made on 37 hips in 32 patients with avascular necrosis of femoral head at early stage by medullary core decompression and implantationation supporting bone and the capsular cutting window. The Harri＇ s hip rating score system and the. Results：of X - ray photos was used to evaluate the clin- ical efficacy of surgery. Results：All the pa- tients were followed up for a mean time of 18months. The pain of the hips was de- creased distinctly. The function of the hips was increased obviously. The X -ray photos showed that the zone of avascular necrosis offemoral head was decreased clearly. The av- erage Harris score increased from preopera- tive 41.2 puints to postoperative 88.1 points. Conclusion： It is sure and inexpen- sive that the effect of treatment avascular necrosis of femoral head by medullary core decompression and implantation supporting bone and the capsular cutting window. This method can be applied to patients with the avascular necrosis of femoral head at early stage.
