Thumb reconstruction by metacarpal lengthening after traumatic loss at the level of the interphalangeal joint.

Cobb Tk, Stocks Gw, May Wf, Strauss Mr, Lewis Rc

Abstract

This paper describes a unique procedure utilized on seven occasions to restore thumb function in amputation at or near the level of the interphalangeal joint. Consisting of two phases, the procedure adds approximately 2.5 cm of functional length to the thumb. The metacarpal bone is lengthened approximately 1.5 cm by a bone-lengthening device, and an additional 1 cm is obtained by deepening the thumb web space.
