At this foundation the Squires curve for the kinematic trajectory of thumb tip was derived. 在此基础上,导出了拇指尖(TT)运动轨迹的Squires曲线。
Objective : To evaluate the merits and demerits of several hand flaps in repairing the thumb tip skin defects. 目的:探讨几种手部皮瓣修复拇指指端皮肤缺损的优缺点及疗效。
Methods 77 cases with pulp defect in thumb tip were treated by pulp replantation, advancing flap of pulp, digital artery island flap and the first adverse dorsal metacarpal flap. 方法77例拇指指腹缺损,通过指腹再植、指掌侧推进皮瓣、指动脉岛状皮瓣、第一掌骨背逆行筋膜皮瓣等法,修复拇指腹缺损。
Conclusion The best reconstruction way of pulp defect in thumb tip is pulp replantation, the second way is to choose the suitable flap according to the size and location of defect. 结论拇指末节指腹缺损治疗,首选再植,其次根据指腹缺损面积及部位,合理选择皮瓣。
