The anatomy of the extensor tendon insertion in the arthritic distal interphalangeal joint: a cadaveric study

Abstract

Dissection of arthritic cadaveric digits revealed an expanded extensor tendon footprint involving the dorsal osteophyte on the terminal phalanx. Osteophyte attachments can be safely released up to the width of a number 15 scalpel blade without risking the integrity of the extensor tendon.
