Extensor pollicis brevis deviation graft operation in case of Z-deformity of the thumb in ulnar palsy--a preliminary case report.

ABSTRACT

This new procedure is described as an analogous operation to Extensor Diversion Graft Operation for correction of claw fingers (Srinivasan H.) (5). The procedure is found useful to stabilise the metacarpophalangeal joint of the thumb preventing or correcting Z-deformity and weakness of the pinch showing many advantages compared to other procedures. A single case is shown as a preliminary report.
