  • 小腿远端皮支链血管皮瓣修复足踝部缺损的疗效观察

    目的 总结小腿远端皮支链血管皮瓣修复足踝部软组织缺损的疗效。 方法2008年5月-2011年10月,收治11例足踝部软组织缺损患者。男9例,女2例;年龄20~70岁,平均46.5岁。其中外伤致软组织缺损8例,伤后至手术时间2 h~21 d;恶性肿瘤切除后缺损3例。缺损范围为4 cm × 4 cm~7 cm × 7 cm;创面伴骨、肌腱外露。采用大小为4.5 cm × 4.5 cm~9.0 cm × 9.0 cm的小腿皮支链血管皮瓣修复缺损。供区直接拉拢缝合或游离植皮修复。 结果1例皮瓣术后发生远端皮缘坏死,经换药后二期修整缝合愈合;其余皮瓣均顺利成活,创面均Ⅰ期愈合。供区植皮均成活;切口Ⅰ期愈合10例,Ⅱ期愈合1例。术后患者均获随访,随访时间6~12个月,平均8个月。皮瓣外形不臃肿,色泽、质地优良,耐磨无破溃,穿鞋行走自如。 结论小腿远端皮支链血管皮瓣不牺牲主要血管及皮神经,手术操作简便,术后成活率高,外观较好,是修复足踝部软组织缺损的理想方法之一。

  • EFFICACY COMPARISON OF END-TO-END AND END-TO-SIDE NEURORRHAPHY IN TREATMENT OF BRACHIAL PLEXUS UPPER TRUNK INJURY

    Objective To study and compare the effect of end-to-end and end-to-side neurorrhaphy between the reci pient’s musculocutaneous nerve and the donor’s ulnar nerve, and to observe the regeneration of peri pheral nerve and muscle refection. Methods Sixty male SD rats (weighing 200-250 g) were randomized into 2 groups (n=30 per group), and made the musculocutaneous nerve injury model. In group A, the donor’s nerve was transected for end-to-end neurorrhaphy.In group B, an epineurial window was exposed and the distal end of the muscle branch of musculocutaneous nerve was sutured to the side of the ulnar nerve. Electromyography was performed, biceps wet weight ratio, muscle fiber cross-sectional area, and count of myel inated nerve fiber (CMF) were measured at 4 and 12 weeks postoperatively. The behavior changes of the rats were observed. Results At 4 weeks, the nerve conduction velocity (NCV) and the latency ampl itude (AMP) of group A were significantly higher than those of group B (P lt; 0.05); at 12 weeks, there was no significant difference in the NCV and AMP between groups A and B (P gt; 0.05). At 4 and 8 weeks, there was no significant difference in biceps wet weight ratio and muscle fiber cross-sectional area between groups A and B (P gt; 0.05). At 4 weeks, the CMF was 230.15 ± 60.25 in group A and 160.73 ± 48.77 in group B, showing significant difference (P lt; 0.05); at 12 weeks, it was 380.26 ± 10.01 in group A and 355.63 ± 28.51 in group B, showing no significant difference (P gt; 0.05). Conclusion Both end-to-end and end-to-side neurorrhaphy have consistent long-term effect in repair of brachial plexus upper trunk injury.
