带血管蒂腓肠肌内侧头肌瓣转移重建髌腱的长期随访

目的 总结胫骨近端侵袭性骨肿瘤广泛切除假体置换手术,应用带血管蒂腓肠肌内侧头肌瓣转移重建髌腱的长期随访结果.方法 胫骨近端肉瘤广泛切除后,应用带血管蒂腓肠肌瓣转移重建髌腱附着,长期随访及评估伸膝动力和并发症.结果 临床治疗69例,对45例生存患者平均随访68.6(24～128)个月,局部复发率8.7%(6/69),伸膝肌力平均4.2级(3.6～5.0),膝关节屈曲平均95°(75°～135°),伸膝平均-2°(0°～12°),5例膝关节不能完全伸直;患肢MSTS功能评分为77%(23.1/30),外观正常.结论 在胫骨近端侵袭性骨肿瘤保肢术中,应用带血管蒂腓肠肌瓣转移重建髌腱,能够恢复伸膝力量,改善软组织覆盖和患肢功能.

Medial gastrocnemius muscle transferring reconstruction the patella tendon with long following-up

Objective To evaluate the long following-up outcome of the medial gastrocnemius muscle transferring reconstruction the patella tendon after the wide resection of aggressive bone tumors in the proximal tibia. Methods With the 69 patients of the osteogenetic sarcoma in the proximal tibia were treated with the wide resection and reconstruction the patella tendon. After the long following up the knee extensor,function and complications were evaluated. Results With the 69 patients, the 45 survival patients were followed up for the average 68.6 (24-128) months. The local recurrence rate was 8.7%(6/69). The strength of knee extending was in the average of grade 4.2(3.6-5.0), the degree of knee flexion was in the average of 95°(75°-135°), the degree of knee extension was in the average of-2°(0°-12°), the knees of five patients cannot fully extension. The MSTS functional score was in the average of 77% (23.1/30). Conclusion During the limb salvage of the proximal tibial aggressive bone tumors, the medial gastrocnemius muscle transferring reconstruction the patella tendon could offer the knee extension strength; improve the soft tissue coverage and functional results.
