Replantation of totally amputated ears

From a total of 1525 replantations or revascularizations performed at our clinic we report three replantations of totally amputated ears. In two the cause of amputation was a car accident and in the third case a dog bite. In the first case no suitable artery for anastomosis was found on the amputated part and the replantation was performed by means of arterialization of the venous system [3, 8, 12]. After 2 days the mild venous stasis subsided, and a normal blood supply to the ear was established. In the two other cases both arteries and veins were sutured without any complications. All three cases healed successfully and completely.     

拇指指尖离断再植

目的 介绍拇指指尖离断再植的临床经验。方法 采用改良逆行再植方法，用三种血运重建的方式对105例拇指指尖离断进行再植。结果 再植105例，成活四例，成活率94.2％，术后手指外形和长度与健指相似，两点辨别觉3～6mm，指甲生长良好。结论 熟悉拇指指尖血管分布规律及再植特点，可以明显缩短再植时间，提高再植成功率。     

手指套脱性断指再植

目的探讨手指套脱性离断伤再植方法的可行性。方法对10例18指手指套脱性离断伤的患者，进行再植术。结果再植18指，术后成活16指，坏死2指，成活率为89％。术后随访5～12个月，手功能和外形满意，再植指两点分辨觉为4～9min，按中华医学会手外科学会上肢部分功能评定试用标准评定：优14指，良2指，优良率达100％。结论手指套脱性离断伤，只要套脱皮肤完整，可以通过再植的方法恢复手部的功能和外形。     

Reimplantation of completely amputated rat limb

A technique for the amputation and immediate reimplantation of rats legs was studied using a microsurgical technique. Complete survival of the reimplanted leg was achieved by basing the blood supply on anastomoses of arteries about 0.4 mm in external diameter. Anastomoses of vessels in that range by interrupted sutures of 10/0 and 11/0 black monofilament nylon proved to be compatible with leg survival. The ultimate survival of the reimplanted limbs depended upon microsurgical technique, preoperative and operative heparinization and external protection during the recovery phase. Animals are alive and using the replanted limb, several months postoperatively.     

Prosthetic rehabilitation of an amputated thumb

Prosthetic rehabilitation of any defect or abnormality of any part of the body must be as indiscernible as possible from the surrounding natural tissues in terms of cosmesis as well as function. Surgical procedures are more likely to meet the requirements of absolute function but the patients' involvement and willingness to undergo extensive and costly procedures like micro-surgical grafting and implants may preclude these procedures. This paper presents an alternative method of prosthetic rehabilitation of an amputated thumb with a heat cured silicone material.
