- See:
- FDP rupture
- FPL rupture
- Teno-synovectomy
- Discussion:
- when flexor tendon ruptures occur, there are two usual causes:
- attrition or direct invasion by tenosynovitis;
- these occur in carpal canal due to invasion or attrition;
- scaphoid bone is most common site for the attrition process
- FPL, FDS, & FDP to index fingers are tendons most often involved w/ attrition ruptures;
- Exam:
- affected finger tends to have an extended appearance;
- Treatment Considerations:
- rheumatoid FDP rupture needs to be distinguished from FDP rupture;
- if both the FDS and the FDP tendons are ruptured, then consider PIP fusion;
- see FPL Rupture:
- most important factor for determining type of treatment is level of tendon rupture;
- w/ tendon ruptures in the palm the distal tendon end may be sutured to the adjacent intact tendon
