Isolated Small Finger Distal Interphalangeal Joint Dupuytren’s Contracture

Abstract EN

Dupuytren’s contracture is a disease involving abnormal myofibroblast proliferation and collagen deposition leading to the formation of pathologic cords in the hand.

Given that Dupuytren’s contractures rarely extend to the distal interphalangeal joint (DIP), affecting only 5% of patients, there are few cases reported in the literature.

Collagenase injection is a frequently used option for minimally invasive treatment of Dupuytren’s disease with greater than a 20-degree joint contracture.

Unfortunately, there is limited research on the effectiveness of these injections in isolated DIP joint deformities.

We present a case of a 61-year-old right hand-dominant male with a 2-year history of isolated right small finger Dupuytren’s contracture at the DIP joint who achieved significant improvement after collagenase injection.
