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.
本研究旨在评估股骨头坏死介入治疗棒植入治疗股骨头坏死的临床和影像学结果。在这项回顾性研究中,对 19 例 23 例股骨头坏死患者进行了随访。在 19 例 23 例坏死的股骨头患者中,有 13 例需要进行全髋关节置换术。这意味着在平均随访 1.45 年后,植入股骨头坏死介入棒的存活率为 44%。与单纯骨芯减压相比,核心减压联合钽股骨头坏死介入植入物的治疗结果并没有显示出更好的结果。这与现有研究相反。此外,本研究还表明,在进行全髋关节置换术时,钽棒取出过程中没有出现问题。
