  • 足底内侧皮瓣修复手小鱼际部软组织缺损

    【摘 要】 目的 探讨足底内侧皮瓣修复手小鱼际部软组织缺损的临床疗效。 方法 2006 年4 月- 2010年12 月,采用带血管神经蒂的足底内侧皮瓣修复6 例手小鱼际部软组织缺损。男4 例,女2 例;年龄15 ~ 46 岁,平均31.5 岁。挤压伤4 例,热压伤1 例,受伤至手术时间 3 ~ 8 h;神经纤维瘤切除后1 例。软组织缺损范围为4 cm ×3 cm ~ 6 cm × 5 cm。合并小指屈指深、浅肌腱断裂1 例,掌骨骨折 2 例,小鱼际部肌肉缺失4 例。皮瓣切取范围为4.5 cm ×3.5 cm ~ 6.5 cm × 5.5 cm。供区游离植皮修复。 结果 术后皮瓣及植皮均顺利成活,创面Ⅰ期愈合。术后患者均获随访,随访时间6 ~ 8 个月。皮瓣外形无臃肿,质地优良,痛、温、触觉存在,术后6 个月两点辨别觉为8 ~ 11 mm,平均 8.6 mm。结论 足底内侧皮瓣质地与小鱼际皮肤相似,修复后外观及耐磨度良好,皮瓣切取后对供区功能影响小,血管走行恒定,口径粗大易于吻合,是修复手小鱼际部软组织缺损较好方法之一。

  • 游离前臂骨间背侧皮瓣修复手指皮肤软组织缺损

    【摘 要】 目的 总结游离前臂骨间背侧皮瓣修复手指皮肤软组织缺损的疗效。 方法 2008 年7 月- 2010 年5 月,收治12 例12 指手指皮肤软组织缺损患者。男9 例,女3 例;年龄17 ~ 35 岁,平均24.5 岁。机器挤压伤3 例,电刨伤5 例,电锯伤4 例。示指7 例,中指4 例,环指1 例。创面缺损范围为3 cm × 2 cm ~ 4 cm × 2 cm。受伤至手术时间 3 ~ 8 h,平均 4 h。采用大小为3.5 cm × 2.5 cm ~ 4.5 cm × 2.5 cm 的游离前臂骨间背侧皮瓣移植修复创面,将皮瓣携带的骨间背侧动、静脉与受区指固有动脉或指总动脉、指背静脉或掌背远端浅静脉吻合。供区直接拉拢缝合。 结果 术后7 d,1 例皮瓣近端坏死,经换药后愈合;其余皮瓣均顺利成活,创面及供区切口均Ⅰ期愈合。患者均获随访,随访时间6 ~ 12 个月,平均9 个月。皮瓣质地优良,局部无臃肿,耐磨无溃疡。术后6 个月皮瓣两点辨别觉为8 ~ 10 mm,平均 9.3 mm。术后6个月手指功能按照中华医学会手外科学会上肢功能评定试用标准评定,获优 4 例,良 6 例,可 2 例。 结论 应用游离前臂骨间背侧动脉皮瓣移植修复手指皮肤软组织缺损可获得较好临床效果。

  • Effectiveness of Drawtex hydroconductive dressing in treatment of early implantation-associated infection and soft tissue defect after internal fixation of tibial fracture

    Objective To investigate the feasibility of Drawtex hydroconductive dressing in treatment of early implantation-associated infection and soft tissue defect after internal fixation of tibial fracture. Methods Thirty-six New Zealand rabbits were used to prepare the model of early implantation-associated infection after internal fixation of tibial fracture, and randomly divided into 3 groups (n=12) . The infected wounds were covered with Drawtex hydroconductive dressing (group A), chitosan solution gauze (group B), and normal saline gauze (group C), respectively. The dressing was changed every 2 days. X-ray films were performed at 1, 14, and 21 days. The gross observation, microbiological evaluation, and histological observation were done at 21 days. Results There was no significant difference in the wound grading according to the Jamesʾ grading criteria between groups at 21 days (χ2=3.713, P=0.156). X-ray films showed no bone destruction in all groups at 1 day; and there was no significant difference in radiographic scores between groups (P>0.05). At 14 days, the mild osteolysis was observed in group B; the radiographic score was significantly lower in groups A and C than in group B (P<0.05), but there was no significant difference between groups A and C (P>0.05). At 21 days, the osteolysis and osteomyelitis were observed in groups B and C; the radiographic score was significantly lower in group A than in groups B and C (P<0.05), but there was no significant difference between groups B and C (P>0.05). Also, the microorganism in bone tissue of group A was less than that of groups B and C (P<0.05); and the difference between group B and group C was not significant (P>0.05). Histological observation showed the mild inflammatory cell infiltration in group A and many inflammatory cells in groups B and C. The Smeltzer histological score was significant lower in group A than in groups B and C (P<0.05); and there was no significant difference between groups B and C (P>0.05). Conclusion Drawtex hydroconductive dressing can be used for the implantation-associated infection after tibial fracture internal fixation. And the effectiveness of Drawtex hydroconductive dressing is better than that of chitosan solution gauze and normal saline gauze.
