目的：介绍以桡侧副动脉后支为蒂的嵌合骨皮瓣游离移植修复手指复杂缺损的临床经验和手术方法。方法采用以桡侧副动脉后支为蒂的游离嵌合骨皮瓣修复8例合并指骨缺损的手指复杂缺损；手术中以相对独立的穿支为蒂切取皮瓣和骨瓣；皮瓣面积5.0 cm×2.0 cm～7.5 cm×4.0 cm，骨瓣大小1.5 cm×0.5 cm～2.5 cm×1.0 cm。结果8例嵌合骨皮瓣均成活良好；骨瓣平均愈合时间5.4(3～6)个月；供区直接闭合，仅遗留线性瘢痕；随访12～18个月，患者满意度高。结论以桡侧副动脉后支为蒂的嵌合骨皮瓣游离移植是修复复杂手部缺损的较好方法。“,”Objective To introduce the clinical experience and surgical methods of transplanting free chimeric radial collateral artery perforator lfaps to repair complex bone and soft-tissue defects in the hands.Methods Eight cases of digital skin defects complicated with phalanx defects were repaired by free chimeric radial collateral artery perforator lfaps. Flaps 5.0 cm×2.0 cm to 7.5 cm×4.0 cm in area and humeral bone segments 1.5 cm×0.5 cm to 2.5 cm×1.0 cm in size were pedicled on independent perforators.Results All the 8 flaps survived well and the transplanted bone fragments united to the host phalanx 3 to 6 ( averaged 5.4 months ) months after the operation. All the donor wounds were closed with direct suture with only linear scar. A 12 to 18 months’ follow-up revealed a high satisfactory rate from the patients.Conclusions The transplantation of free chimeric radial collateral artery perforator lfap is a good option to repair complex bone and soft-tissue defects in hands.
