Introduction
The human hand is a complex anatomic entity consisting of many muscles, nerves, and vessels, thus providing a special ability to perform accurate and meticulous movements. In this group of muscles are the four dorsal interosseous muscles.
Case presentation
A distinct supernumerary fourth dorsal interosseous muscle was found in the right hand of the cadaver of a 76-year-old Caucasian man without any other concomitant abnormality.
Conclusions
The presence of such an additional muscle in the hand should be considered in the management of hand deformities, whether the treatment is conservative or surgical.
