Avulsion of the ring finger flexor digitorum profundus tendon: an experimental study.
The results of an experimental study of the breaking strength of the tendon-bone junction of the flexor digitorum profundus tendon in cadaver specimens indicates a significantly weaker insertion of the ring finger compared to the middle finger. This explains in part the more frequent occurrence of avulsion of the ring finger profundus tendon as observed clinically.
