本研究的目的是评估股骨头骨坏死干预棒植入治疗股骨头骨坏死的临床和影像学结果。在这项回顾性研究中，对19例23例股骨头坏死患者的随访进行了评估，这些患者接受了骨坏死干预植入物的治疗。19例患者中有23例坏死股骨头，其中13例需要全髋关节置换术。这意味着骨坏死干预棒植入后的平均随访时间为1.45年，生存率为44%。髓核减压联合植入钽骨坏死干预植入物后的结果与单独髓核减压相比没有显示出更好的结果。这与现有的研究相反。此外，本研究显示，在全髋关节置换术中，钽棒的外植过程中没有出现任何问题。
The aim of this study was to evaluate the clinical and radiological outcome of the treatment of osteonecrosis of the femoral head by implantation of an osteonecrosis intervention rod. In this retrospective study the follow-up of 19 patients with 23 osteonecrotic femoral heads treated with implantation of an osteonecrosis intervention implant was assessed. From 19 patients with 23 necrotic femoral heads, there were 13 cases in which a total hip replacement was necessary. This implies a survival rate of 44% after implantation of an osteonecrosis intervention rod after a mean follow-up of 1.45 years. The outcome after core decompression combined with the insertion of a tantalum osteonecrosis intervention implant did not show superior results compared to core decompression alone. This is in contrast to existing studies. In addition, this study showed that in cases of total hip replacement, no problems appeared during explantation of the tantalum rod.
