  • 封闭式负压引流联合前臂皮神经营养血管皮瓣修复手掌皮肤缺损

    总结封闭式负压引流(vacuum sealing drainage,VSD)联合前臂皮神经营养血管皮瓣修复手掌皮肤缺损的临床疗效。 方法 2005 年6 月- 2006 年5 月,收治12 例手掌皮肤缺损患者。男7 例,女5 例;年龄17 ~ 45 岁。挤伤3 例,电锯伤2 例,绞伤4 例,电烧伤1 例,爆炸伤2 例。缺损范围5 cm × 4 cm ~ 7 cm × 7 cm。采用VSD 待创面肉芽组织新鲜、感染控制后,用前臂内、外侧皮神经营养血管皮瓣移位修复手掌皮肤缺损,皮瓣范围6 cm ×5 cm ~ 8 cm × 8 cm。 结果 术后1 例皮瓣远端部分坏死,1 例因血肿压迫出现静脉危象,经对症处理后愈合。余患者皮瓣Ⅰ期愈合。供区成活良好。患者获随访4 ~ 15 个月。根据中华医学会手外科学会功能评定标准:腕关节、掌指关节功能均为优;1 例肌腱功能评分为良,其余为优;感觉评定S1 1 例,S2 2 例,S3 5 例,S3+ 2 例,S4 2 例。 结论 VSD 能减少创面感染机会,为皮瓣修复提供良好组织床。前臂皮神经营养血管皮瓣移位修复手掌部组织缺损,具有耐磨、无挛缩、重建感觉以及色泽与原皮肤相近等优点,是修复手掌部皮肤缺损的良好方法之一。

  • Treatment of severe distal humeral bone defects with three-dimensional printing technology

    ObjectiveTo explore the application of three-dimensional (3D) printing technology in precise and individualized surgical treatment of severe distal humeral bone defect.MethodsFive patients with severe distal humeral bone defects were treated with customized 3D printing prostheses between December 2010 and December 2015. There were 4 males and 1 female, with an age of 23-57 years (mean, 35 years); and the length of the bone defect was 5-12 cm (mean, 8 cm). The cause of injury was mechanical injury in 2 cases and strangulation in 3 cases. All of them were the open fracture of Gustilo type Ⅲ. There were 2 cases of radial fracture, 1 case of cubital nerve injury, and 3 cases of radial nerve injury. The time from injury to one-stage operation was 6-18 hours (mean, 10 hours). The operation time, intraoperative blood loss, and intraoperative fluoroscopy were recorded. During follow-up, the anteroposterior and lateral X-ray films of the elbow joints were performed to identify whether there was prosthesis loosening; Mayo Elbow Performance Score (MEPS) and upper extremity Enneking score were used to evaluate limb function.ResultsThe operation time was 140-190 minutes (mean, 165 minutes). The intraoperative blood loss was 310-490 mL (mean, 415 mL). The intraoperative fluoroscopy was 1-3 times (mean, 1.6 times). Five patients were followed up 14-38 months (mean, 21 months). The wound exudate occurred in 1 case and cured after anti-inflammatory local dressing change; the subcutaneous hematoma occurred in 1 case, and improved after color Doppler ultrasound guided puncture and drainage. The MEPS scores and the Enneking scores were all significantly improved when compared with preoperative ones (P<0.05). Except MEPS score between 6 and 12 months after operation had no significant difference (P>0.05), there were significant differences in MEPS scores and Enneking scores between the other time points (P<0.05). During the follow-up, no prosthetic loosening or joint dislocation occurred.Conclusion3D printing technology can achieve personalized treatment of severe distal humeral bone defects, obtain relatively good elbow joint function, and has less postoperative complications and satisfactory effectiveness.

  • Application of composite tissue flaps pedicled with distal perforating branch of posterior tibial artery for repairing distal leg defects

    Objective To investigate the clinical application and effectiveness of the composite tissue flaps pedicled with perforating branch of posterior tibial artery for repairing distal leg defects. Methods Between September 2014 and August 2017, 12 patients with skin and bone defects of distal leg were repaired with the composite tissue flaps pedicled with perforating branch of posterior tibial artery. There were 8 males and 4 females with an average age of 41.3 years (range, 25-66 years). The causes of injury included traffic accident injury in 7 cases, heavy crushing injury in 2 cases, tibial osteomyelitis with soft tissue ulcer and necrosis in 2 cases, and bone and soft tissue defect after resection of bone tumor in 1 case. Eight patients underwent primary repair, and 4 patients underwent second-stage repair. The size ranged from 6 cm×4 cm to 10 cm×7 cm in skin flap, from 4.0 cm×2.5 cm to 8.0 cm×6.0 cm in muscle flap, and from 4 cm×2 cm×2 cm to 5 cm×4 cm×4 cm in tibial bone flap. Tibial defects of the donor region were repaired by autologous iliac bone grafting, and the wounds were sutured directly in 7 cases and repaired by autologous skin grafting in 5 cases. Results All composite tissue flaps survived and both the recipient and the donor wounds healed primarily. All patients were followed up 6-12 months, with an average of 10.8 months. The appearance, color, texture of the composite tissue flaps and ankle function were satisfactory. X-ray films showed that the bone flap at the tibia defect and the ilium graft at the donor site both healed well at 6 months after operation. Conclusion The composite tissue flaps pedicled with perforating branch of posterior tibial artery has abundant blood, and it is a good donor region for repairing the distal leg defects combined with circumscribed bone defect.
