Pollicization after traumatic amputation of the thumb.

Nineteen pollicizations were performed over a period of 17 years in adults after traumatic thumb amputation. Seven normal fingers were pollicized with very satisfactory results. Eleven previously damaged fingers were also pollicized and all of these resulted in diminished motion. Because preoperative arteriograms give useful, often unexpected information, they should be performed if vascular damage is suspected. Application of a pedicle flap should be performed before pollicization when there is excessive scarring or inadequate skin cover. This permits easier design of skin flaps during the procedure and minimizes the chance of a web-space contracture. Fourteen patients (74%) required secondary procedures, tendolysis being the most common problem.
