Knuckle pads causing extensor tendon tethering.
A case of Dupuytren's contracture is described, in which, both clinically and histologically, knuckle pad lesions involved the extensor tendons. Surgical excision of the Dupuytren's tissue from the dorsal aspect of the proximal interphalangeal joints, freeing of the lateral extensor slips and posterior capsulotomy resulted in marked functional improvement.
