末节远端断指再植疗效分析

An Analysis of Results of Replantation of Severed Phalanges Distalis Digitorum Manus

目的：总结33例末节远端断指再植的治疗体会。方法：末节远端断指再植，采用单根注射器针头指骨内固定，吻合指动脉弓分支动脉、指腹静脉等方式重建血运，吻合神经，再植。结果：再植33例末节远端断指，29指成活，3指失活，再植成活率90．6％，术后再植指外形、运动、感觉功能恢复良好。结论：彻底地清创，精确吻合血管，认真修复神经，早期积极功能锻炼是提高末节远端断指再植成活率和疗效的主要因素。

Objective：To sum up experience with 33 cases of replantation of severed phalanges distalis digitorum manus.Methods： In the replantation operation the internal fixation of phalanx was performed with single syringe needle. The blood - vascular system was reconstructed by anastomosing the branches of digital arterious arches and venae digitales volares propriae,and then the nerves were anastomosed and the replantation was performed. Resin： From the 33 severed digiti 29 were replanted successfully,and 3 suffered defeal （the rate of replantation success was 90.6%） .The appearance,activity and sensibility of the replanted digiti were gotten back well. Conclusion： To thoroughly debride,aeeurately anastomose blood vessels, seriously repair nerve tissue and take early and active exercises are brimary factors of improving the rate of successful replantation of severed digifi.
