Domestic research progress in replantation of rotational avulsed thumbs / 中华显微外科杂志

ABSTRACT

Thumb loss will seriously affect hand function. Replantation of a severed thumb is indispensable if possible. There is a higher level of difficulty in replantation of rotational avulsed thumbs when compared with other type of severed digit. But with the development of microsurgery technique and instruments, the survival rate of replantation has been significantly increased. How to achieve a simple and fast operation, minimal trauma at the donor site and the best function recovery, is the task for future exploration. However, there exists obvious variance in individual differences among surgeons, due to the lack of a unified standard surgical procedure. Therefore, based on a study of domestic literatures, this article reviews the specific methods in handling of bones, repair of nerve, tendon and blood vessels as well as the skin coverage applied in replantation of thumb rotation avulsion detachment. This article summarises the most clinical widely used and ideal operations and provides a reference for the surgeons.
