摘要
目的评估数字骨科技术在股骨恶性肿瘤治疗中的应用价值。方法 1例股骨低度恶性肌纤维母细胞性肉瘤,应用薄层CT扫描获取病变部位的二维数据,计算机三维重建解剖学模型,设计截骨范围、个体化异体股骨重建及模拟手术过程。按照计算机辅助设计方案切除股骨肿瘤组织,采用右股骨肿瘤精确切除+大块异体骨移植+髓内钉内固定。结果与结论数字骨科技术精确切除右股骨低度恶性肌纤维母细胞性肉瘤,术后1个月患者开始扶拐患肢不负重行走,术后4个月右下肢关节活动良好,无疼痛不适。术后X射线片提示股骨重建效果满意。术后无不良并发症。数字骨科技术将会使股骨肿瘤手术治疗更精确、更可靠、更方便,疗效更佳。
Objective To evaluate the value of computer aided design in the treatment of femur tumor. Methods One case with femoral low - grade myofibroblastic sarcoma was checked with lamellar CT scanning, which acquired some two - dimensional data in disease area. The three - dimensional reconstruction of anatomical model, design of cutting bone extent, design of individual prosthesis and sham operation were made by computer. Based on computer aided design proposal, femur tumor was reseeted, using a chunk of allogeneic bone graft + intramedullary nailing fixationg to reconstruction femoral. Results and Conclusion Digital orthopedic technology precise excision of the right femur low grade muscle fiber mother cell sarcoma, a month after surgery the patient began crutches limb, four months after surgery the patients right lower limb joint activities were satisfied, without pain. Postoperative X - ray films showed satisfactory results femoral reconstruction. There were no adverse complications. The digital orthope- dic technology can improve operation accuracy, reliability, convenience and curative effect.
