髓芯减压植骨支撑术治疗股骨颈骨折术后股骨头坏死的早期疗效观察

Clinical study of core decompression with bone grafting on the osteonecrosis of the femoral head after femoral head fracture

目的探讨髓芯减压植骨支撑术治疗股骨颈骨折术后股骨头缺血性坏死的早期疗效。方法对21例行三根钉手术治疗的股骨颈骨折患者,经X线、CT、ECT或MRI确诊为股骨头坏死,所有患者采用髓芯减压植骨支撑术治疗。依据ARCO分期:Ⅰ期2髋,ⅡA11髋,ⅡB6髋,ⅡC1髋,IIIA1髋,术前及术后所有患者采用Harris髋关节评分系统进行评分、影像学检查并加以比较。结果随访9~18个月,Harris评分由术前(73.4±7.2)增加到术后(89.4±7.9),优良率85.2%。结论采用髓芯减压植骨支撑术治疗股骨颈骨折术后股骨头坏死,恢复了股骨头前外侧柱的生物力学稳定,促进了坏死病灶的修复,对患者具有良好的早期疗效。

Objective To explore the curative effect of the treatment of bone grafting on the osteonecrosis of the femoral head after femoral head fracture.Methods 21 cases of the osteonecrosis of the femoral head after femoral head fracture.were treated with the treatment of bone grafting.Results The mean preoperative Harris hip score(73.4±7.2) points by the increase on average(89.4±7.9) points.Conclusion Combined treatment of the osteonecrosis of the femoral head after femoral head fracture.with bone grafting proves to have good curative effects in the short-term treatments.
