Tantalum rod implantation with vascularized bone transplantation has been reported to be an effective method for the treatment of osteonecrosis of the femoral head (ONFH). However, long-term follow-up results were unclear. Sixty-five patients (71 hips) with ONFH treated with this technique were retrospectively reviewed. According to the Association Research Circulation Osseous (ARCO) classification, 21 hips were stage II, 30 were stage III, and 15 were stage IV. Sixty-one patients (66 hips) were followed for more than 10 years. Fifteen hips had to be converted to total hip arthroplasty (THA), the proportion of THA conversion surgery over 10 years postoperative was 4.76% for stage II, 16.7% for stage III, and 60% for stage IV, respectively. The 10-year joint-preserving success rate of the entire group was 77.2%. The Harris Hip Score (HHS) in the patients not receiving THA therapy increased from a mean of 51.35 points (ranged from 32 to 62 points) to 90.12 points (ranged from 72 to 99 points). The technique of tantalum rod implantation with vascularized bone grafting was an effective joint-preserving method for the treatment of ARCO stage II-III ONFH.
钽棒植入联合带血管蒂骨移植已被报道是治疗股骨头坏死（ONFH）的一种有效方法。然而，长期随访结果尚不清楚。对采用该技术治疗的65例（71髋）ONFH患者进行了回顾性分析。根据骨循环研究协会（ARCO）分类，21髋为II期，30髋为III期，15髋为IV期。61例患者（66髋）随访超过10年。15髋不得不转换为全髋关节置换术（THA），术后10年THA转换手术的比例在II期为4.76%，III期为16.7%，IV期为60%。整个组的10年保髋成功率为77.2%。未接受THA治疗的患者的Harris髋关节评分（HHS）从平均51.35分（范围为32至62分）提高到90.12分（范围为72至99分）。钽棒植入联合带血管蒂骨移植技术是治疗ARCO II - III期ONFH的一种有效的保髋方法。
