Objective: To investigate effectiveness of the medial ankle branches propeller "Tennis racket-like" flap in repair of heel-ankle tissue defect.
Methods: Between June 2011 and June 2016, 50 patients with heel-ankle tissue defects were treated. There were 40 males and 10 females, with a median age of 35.6 years (range, 6-58 years). The defects were caused by trauma in 44 cases, scar deformity after trauma in 2 cases, chronic ulcer in 2 cases, and squamous cell carcinoma in 2 cases. The defects located at heel in 20 cases, ankle in 15 cases, and heel-ankle in 15 cases. The size of heel-ankle tissue defect ranged from 3.5 cm×2.0 cm to 13.0×10.0 cm. The course of disease ranged from 3 hours to 2 months (mean, 28 days). All wounds were repaired by the medial ankle branches propeller "Tennis racket-like" flap in a size of 3.8 cm×2.2 cm-13.4 cm×10.3 cm. The donor site was directly sutured in 5 cases or repaired by skin grafting in 45 cases.
Results: All flaps survived and wounds healed by first intention. Partial necrosis of skin grafting occurred in 1 case, and the wound recovered by change dressing. The other skin grafting survived and wounds healed by first intention. Forty-eight patients were followed up 12 months after operation. The appearance, sensory, and function of repaired heel-ankle flaps were satisfactory.
Conclusion: For heel-ankle tissue defect repair, the medial ankle branches propeller "Tennis racket-like" flap has advantages of the high survival rate, reliable blood supply, and sensory recovery.
目的: 总结“网球拍”状内踝上穿支螺旋桨皮瓣修复跟踝部软组织缺损的疗效。.
方法: 2011 年 6 月—2016 年 6 月，收治 50 例跟踝部软组织缺损患者。男 40 例，女 10 例；年龄 6～58 岁，中位年龄为 35.6 岁。缺损原因：外伤 44 例，外伤后瘢痕畸形 2 例，慢性溃疡 2 例，鳞癌 2 例。缺损部位：足跟部 20 例，踝部 15 例，跟踝部 15 例。软组织缺损范围为 3.5 cm×2.0 cm～13.0 cm×10.0 cm。病程 3 h～2 个月，平均 28 d。采用“网球拍”状内踝上穿支螺旋桨皮瓣修复，皮瓣切取范围 3.8 cm×2.2 cm～13.4 cm×10.3 cm。供区直接缝合（5 例）或植皮修复（45 例）。.
结果: 术后皮瓣均顺利成活，创面Ⅰ期愈合。供区 1 例植皮部分坏死，经换药后愈合；其余植皮均顺利成活，切口均Ⅰ期愈合。术后 48 例获随访 12 个月，皮瓣修复处外形、功能恢复良好，感觉恢复良好。.
结论: “网球拍”状内踝上穿支螺旋桨皮瓣成活率高，血供可靠，移位后能恢复感觉，是修复跟踝部缺损较理想的方式之一。.
