目的 研究拇指及其他手指指腹缺损修复的一种可行方法。方法 对1987年来应用吻合血管游离趾腹皮瓣移植，修复拇指及其他手指指腹缺损19例。结果 19例移植皮瓣全部成功。术后随访3个月－12年，修复的指腹外观饱满，皮纹清晰，两点分辨觉为6－8mm，修复指持物时无疼痛；供足于移植术后以皮片修复，无瘢痕及胼胝形成，无任何功能影响。结论 与其他修复指腹缺损的方法相比，趾腹游离皮瓣移植对单一的指腹缺损修复更加理想。

Free pulp flap of toe in repairing thee pulp defect of finger

OBJECTIVE: To investigate a method in repairing pulp defects of thumb and finger. METHODS: To examine and analyze 19 case of pulp defect of thumb and finger repaired with free pulp flap of toe since 1987. RESULTS: All the transplanted pulp flaps in 19 cases are survived and are followed up from 3 months to 12 years. All the digits recovered good out appearance with normal skin creases and ridges. The two-point discriminations are 6-8 mm. The repaired thumb or finger are free of paint during pinching and grasping. The split thickness skin grafts on the donor toes yield no hypertrophic scar and no callousity occurred on the donor feet. No detrimental influence occurred on the donor feet. CONCLUSION: The free pulp flap transfer has obvious advantages than any other methods in repairing pulp defects of single finger by, first, good outward appearance, second, quality of the skin over donor flap is almost as rub resistant as recipient finger, third, anastomosis of the digital nerves give functional influence, finally, short rehabilitation period however, the operation requires microsurgical technique and has a risk of failure.
