Is it possible to reattach amputed finger? — Dharshini R, resident of Perambur

Finger amputations can be reattached successfully irrespective of the level of cut. However it is ideal that the amputated part is brought to the hospital within six hours from the accident. But for distal finger amputation few more hours of delay is not a problem. It is also important to properly preserve the amputated part before reaching the hospital. The scope of plastic surgery has increased over the years and it plays a significant role in case of amputations.
