Subcutaneous rupture of flexor tendons of the fingers is a relatively uncommon occurrence.
Von Zander's report in 1891 of a rupture involving the flexor pollicis longus tendon was the first reported flexor tendon rupture in the forearm and hand.
Three patients have been treated recently for flexor digitorum profundus tendon ruptures of the little finger.
In two cases early surgical treatment gave excellent result. In one case conservative treatment by plaster cast fixation gave excellent result.
