甲中份以远指尖再植

目的探讨甲中份以远指尖离断再植的临床特点和预后。方法2001年8月～2005年8月,对16例1甲中份以远指尖离断采取只吻合动脉的方法再植,术后小切口放血。结果16例离断指尖中,成活14例,坏死2例,再植成功率为87．5%。对再植成功的12例随访3～12个月,成活指体饱满和指甲外形满意,静态两点辨别觉为3～6mm。结论甲中份以远的指尖离断冉植是恢复手指外形和功能的最佳治疗方法,具有较高的成功率。但要求术者具有较高的小血管吻合技术,指尖损伤程度和较高的医疗费用也在考虑之中。

Replantation of fingertips distal to the middle nail

Objective To investigate the clinical features and prognosis of replantation of fingertips distal to the middle nail. Methods Between August 2001 and August 2005, 16 fingertips amputated in the lshikawa zone I were replanted. We anastomosed only the digital arteries, and adopted postoperative bloodletting. Results Fourteen fingertips survived, and two failed. The survival rate was 87.5%. Of the 14 successfully replanted fingertips, 12 were followed up from 3 to 12 months. The length and appearance of the fingertips recovered and good joint motion were maintained. Their two-point discriminations ranged from 3 to 6 ram. Conclusion Fingertip replantation is an optimal treatment for fingertip amputation distal to the middle nail to regain satisfactory appearance and function of the digits with a high survival rate, but severe crush injury to the amputated part and high cost should be taken into consideration.
