This study describes the outcomes of internal bone transport with magnetic nails in five cases of traumatic segmental femoral bone defects.
Five patients with open fracture of the femur and diaphyseal bone loss were included between May 2018 and August 2020. The mean femoral defect was 8.7 cm (range 5.6-16.0).
We used plate-assisted bone segment transport (PABST) with PRECICE magnetic nails.
All five patients have fully consolidated. The mean consolidation time and index were 7.5 months and 0.8 mo/cm, respectively. The mean follow-up was 21.3 months. The main complications were reduced knee ROM, mild varus deformity and plate bending. Post-operative SF-36, Oxford Knee scores and ED-5Q-5L scores were also compiled for four of five patients. SF-36 and Oxford Knee scores were reported without pre-injury data for comparison. ED-5Q-5L index and VAS were compared UK population norm and were both found to be statistically insignificant (p = 0.071 and p = 0.068, respectively).
Bone transport with magnetic nails has the capacity to obtain good functional recovery in long bone defects despite variable outcome pictures. In response to variable outcome reporting in the literature, we propose a standard reporting template for future studies to facilitate more rigorous analyses.
本研究描述了 5 例创伤性股骨节段性骨缺损患者应用磁性钉进行骨内搬运的结果。
2018 年 5 月至 2020 年 8 月期间，纳入 5 例股骨干开放性骨折合并骨干骨缺损患者。股骨干缺损平均长度为 8.7cm（5.6-16.0cm）。
我们使用带 PRECICE 磁性钉的钢板辅助骨段搬运（PABST）。
所有 5 例患者均完全愈合。平均愈合时间和指数分别为 7.5 个月和 0.8mo/cm。平均随访时间为 21.3 个月。主要并发症为膝关节活动度减小、轻度内翻畸形和钢板弯曲。术后还对 5 例患者中的 4 例进行了 SF-36、Oxford Knee 评分和 ED-5Q-5L 评分的编译。SF-36 和 Oxford Knee 评分报告没有术前数据进行比较。ED-5Q-5L 指数和 VAS 与英国人口常模进行比较，均无统计学意义（p=0.071 和 p=0.068）。
尽管结果不一，但磁性钉骨搬运术有能力获得长骨缺损的良好功能恢复。针对文献中结果报告的差异，我们提出了一个标准报告模板，以便为未来的研究提供更严格的分析。
