Digital amputation, replantation, and cold intolerance.

In a controlled, retrospective, clinical study, the relationships between traumatic digital amputation, digital replantation, and cold intolerance were investigated. The results of the investigation indicate that cold intolerance is a major reason for disability after digital amputation. They also indicate that the cold intolerance experienced after digital replantation is due to the original injury, and that it is not aggravated by the reconstructive surgery. Cold intolerance, in and of itself, is not a contraindication to digital replantation, regardless of whether the patient lives or works in high- or low-temperature environments.
