(足母)长屈肌腱移位替代跟腱治疗跟腱缺损的疗效分析

目的 探讨(足母)长屈肌腱移位替代跟腱治疗6 cm以上跟腱缺损的疗效.方法 2005年1月至2009年2月采用(足母)长屈肌腱移位替代跟腱治疗19例跟腱缺损患者,男13例,女6例;年龄20～61岁,平均(42.6±8.2)岁;跟腱炎清创后跟腱缺损15例,其中10例合并急性跟腱断裂;陈旧性跟腱断裂4例.跟腱断裂至手术时间为0～6个月(平均2.6个月).跟腱缺损长度为6～10 cm.19例患者均采用两切口(足母)长屈肌腱移位替代跟腱术治疗.记录患者术后3个月、1年及末次随访时的踝关节活动度、美国足踝外科协会(AOFAS)踝与后足评分与视觉模拟法(VAS)疼痛评分,并进行统计学比较.评价患者术后足踝部功能的恢复情况及患者的满意度. 结果 19例患者术后获12～48个月(平均22.2个月)随访.患者末次随访时踝关节背伸、跖屈及AOFAS踝与后足评分平均分别为17.8°±1.9°、39.1°±2.3°及(91.8±1.7)分,与术后3个月比较差异均有统计学意义(P＜0.05),与术后1年比较差异无统计学意义(P＞0.05),术后3个月与术后1年比较差异有统计学意义(P＜0.05);VAS疼痛评分平均为(1.0±0.7)分,与术后3个月和术后1年比较差异均有统计学意义(P＜0.05),术后3个月与术后1年比较差异有统计学意义(P＜0.05).术后患者对手术满意率达100%. 结论 (口止母)长屈肌腱移位替代跟腱术是一种有效的手术方式,适用于跟腱较长缺损时的重建治疗.手术可以明显解除疼痛,改善足部功能,且对足部影响较小.

Evaluation of flexor hallucis longus tendon transfer as a treatment for Achilles tendon defects of more than 6 cm

Objective To evaluate the clinical results of flexor hallucis longus (FHL) tendon transfer in treatment of patients with Achilles tendon defects of more than 6 cm. Methods Between January 2005 to February 2009, 19 patients with Achilles tendon defects, 13 males and 6 females, were treated with FHL tendon transfer. Their ages ranged from 20 to 61 years, with an average of (42. 6 ± 8.2)years. Fifteen defects were found during tendonitis debridement, and 4 were old ruptures. Time from rupture to surgery ranged from 0 to 6 months (average, 2.6 months). Defects were 6 cm to 10 cm long. Procedures were performed in a two-incision manner. The postoperative ROM of ankle joint, American Orthopaedic Foot and Ankle Society(AOFAS) and visual analogue scale(VAS) scores were recorded at 3 months, 12 months,and the last follow-up. The results were statistically analyzed to evaluate the functional recovery. Results Follow-ups lasted from 12 to 48 months (average, 22. 2 months). At the last follow-up, the average ROM of ankle joint was 17.8°± 1.9° at dorsal flexion and 39.1°±2.3° at plantar flexion, and the last average AOFAS score was up to (91.8 ± 1.7), significantly different from those at 3 months after surgery (P＜0.05), but not significantly different from those at 12 months (P＞0.05). The difference were significant between the results of 3 months and 12 months (P＜0.05). The last average VAS score was (1.0±0.7),significantly different from those at 3 months and 12 months(P＜0.05) . There was also significant differences between the VAS scores of 3 months and 12 months (P＜0.05). Patient's satisfaction was 100%.Conclusion FHL tendon transfer is an efficient procedure for long Achilles tendon ruptures associated with tendonitis in relieving pain and maintaining the function of ankle joint.
