The Hip: Preservation, Replacement and Revision

Type I FDP Avulsion

- Discussion:
    - tendon retracted to the palm, held up by the lumbrical origin
    - tendon retracts into palm, severing all blood supply and creating extensive scarring in tendon sheath;
    - vincula are ruptured;
    - patients are tender in palm, but able to fully flex PIP joint;
    - location of tendon end often corresponds to point of maximal tenderness in palm;
    - repair within 7 to 10 days is required;
    - in type I and II injuries the tendon end will enlarge after 10 days to such a size that it is impossible to thread the tendon
             back thru the digital sheath
