|
The ring avulsion injury is that accidental taction upon a ring shears the skin and varying amount of tissue from the fingers, furthermore, it is often accompanied with dislocation of joints or fracture of phalangeal bones.
In the past, this injury has led to reconstruction by distant flap or primary amputation(or Ray amputation) with results that were often less desirable.
Recently, the development of microsurgical technique makes it possible to get more acceptable result in reconstruction of severe ring avulsion injury functionally and cosmetically.
The advantage of microsurgical reconstruction for ring avulsion injury is that it makes available to get more functional digit without staged operation.
We experienced three patients with ring avulsion injury(Carroll Classification Class N) among 600 patients who underwent micosurgical replantation of hands and digits.
They were operated with micosurgical anastomoses and two cases of them were successfully replanted leading to useful finger.
Average TAM of each digit was 217´(one 210´, the other 225´) and average 2PD was 8.5 mm(one 7mm, the other 10mm)
