【摘要】 １９８４年４月～１９９４年３月，用自体甲趾骨片皮瓣包裹冷冻异体手指骨—关节一肌腱复合组织，并联第２足趾游离移植再造手抬１５例，共再造拇、手指３１指。经１个月～８年随访，功能及外形良好，认为此法具有多造手指、少切足趾的优点。对造指部位选择、虎口狭小、血管危象及异体关节之变性吸收等问题，提出治疗及预防的方法。冷冻保存尸手能降低异体组织的抗原性，有利于在宿主体内存活。强调急诊截指时应尽量多保留手部活组织，为后期手指再造创造条件。更多还原

【Abstract】 From April 1984 to March 1994,31 reconstructive thumbs or fingers were followed up,in-cluding 16 cases with free neurovascular big toe nail skin flap and frozen preserved phalanx-joint-tendon composite allografts as well as 15 cases with free second toe transfer.The method had theadvantage of more fingers could be reconstructed and fewer toes would be lost.The decision ofthe site of reconstruction of finger,the augmentation of narrow web space between the thumband the index finger,the prevention and treatment of vascular crisis and the degeneration of allo-genic joint were discussed.It had been found that preserving the allogenic flnger below-30℃may lower the immunoreaction of the allogenic tissues.It was emphaslzed that the viable tissuesshould be preserved during the emergency debridement,so as to facilitate the following recon-struction procedure.更多还原
