第二足趾改形移植再造拇手指

目的 研究第二足趾改形移植方法 ,使再造后的拇手指外观更接近手指. 方法 切取第二足趾腓侧趾动脉皮瓣旋转嵌入狭窄部;在趾腓背侧设计皮瓣,在趾腓侧动脉皮瓣胫侧加设计一横形皮瓣称"T"皮瓣、在横形皮瓣的胫侧加一纵形皮瓣称"H"皮瓣.镶嵌在第二足趾的狭窄的两侧和跖侧.应用在不同形状和不同手指再造. 结果 再造17例22指,手指全部成活,1例趾动脉旋转皮瓣部分坏死,术后1～24个月随访,再造拇手指的外形明显改善,指端变小,趾腹酷似手指指腹,狭窄凹陷区饱满,趾间关节明显伸直. 结论 改形移植方法 能较好改变第二足趾的外形.使之更接近正常的拇指和手指.

Reconstruction of finger with reshaped second toe

Objective To improve the outward appearanee in toe-to-hand transfer,a reshaped procedure of second toe was studied. Methods In reconstructing a finger with second toe transfer,a piece of flap from the fibular side of the second toe,or/and a H-shaped flap from the tibial of great toe were designed and transferred to the volar side in order to obliterate the constriction below the toe pulp. Results In 17 patients,22 fingers reconstructed with these procedure,ouly one rotation flap necrosis partly.The appearance of the newly reconstructed thumbs and fingers were improved,the pulp of reconstructed finger was similar to a natural finger, the narrow neck of second toe was well-stacked,and the interpbalangeal joint was straighten. Conclusion Reconstructed finger with this reshaped second toe is similar to a normal finger.
