Present the preliminary results of a case series using the surgical ankle arthrodesis technique with an intramedullary retrograde nail for bone tumors.
We present the preliminary data of 4 patients, 3 males and 1 female, with a mean age of 46,2 (range 32 to 58) years, with histology proven Giant Cell Tumour of bone in 3 and osteosarcoma in 1. The mean resection length of distal tibia was 11,75 (range 9 to 16) cm, and all the patients underwent reconstruction with a tibiotalocalcaneal arthrodesis with an intercalary allograft fixed by a retrograde intramedullary nail.
Oncological follow-up evolved without evidence of local recurrence or disease progression in all patients. After a mean time of 69.5 (range 32 to 98 months), patients had a mean MSTS12 functional score of 82.5% (range 75 to 90). All tibial arthrodesis and diaphyseal osteotomy sites were fused within 6 months with a return to activities without complications related to coverage skin or infection.
No complications were recorded; all arthrodesis and diaphysial tibial osteotomy sites fused by 6 months, and the mean follow-up of those patients was 69,5 (range 32 to 988) months, with a mean functional MSTS score of 82,5% (range 75-90). Level of Evidence: IV; Retrospective Case Series.
展示一系列使用髓内逆行钉进行踝关节融合术治疗骨肿瘤的初步结果。
我们展示了4例患者的初步数据，其中男性3例，女性1例，平均年龄46.2岁（范围32至58岁），组织学证实3例为骨巨细胞瘤，1例为骨肉瘤。胫骨远端平均切除长度为11.75 cm（范围9至16 cm），所有患者均接受了经胫距跟关节融合术，采用间置同种异体骨移植并用逆行髓内钉固定进行重建。
肿瘤学随访显示所有患者均无局部复发或疾病进展的证据。平均69.5个月（范围32至98个月）后，患者的平均肌肉骨骼肿瘤协会（MSTS）12功能评分为82.5%（范围75至90）。所有胫骨融合术和骨干截骨部位均在6个月内融合，患者恢复活动，无与覆盖皮肤或感染相关的并发症。
未记录到并发症；所有融合术和胫骨干截骨部位均在6个月内融合，这些患者的平均随访时间为69.5个月（范围32至988个月），平均功能MSTS评分为82.5%（范围75 - 90）。证据水平：IV级；回顾性病例系列。
