The Hyphecan cap: a biological fingertip dressing.

An occlusive biological dressing, the Hyphecan cap, was evaluated in the management of full-thickness pulp defects of fingers and thumb in 20 consecutive patients. The cap was applied directly to the tip of the injured finger and allowed to separate gradually over the course of several weeks as new skin regenerated. This approach proved simple and effective in achieving a good functional and cosmetic result within a relatively short time, and eliminated the pain and discomfort associated with conventional dressing changes. We recommend the use of this dressing material in the Accident and Emergency department for the out-patient management of de-epithelializing fingertip injuries in both children and adults.
