- tendon laceration is usually transverse w/ minimal retraction; - often extends into the PIP joint; - lateral bands are often spared, but may be subluxed volarly due to disruption of the triangular ligament; - left untreated, a boutonniere injury may develop;

- Anatomy of EDC:
- note that EDC is less tolerant of shortening than FDS due to differential in tendon excursion (50 mm compared to 70 mm, respectively);

Mannerfelt syndrome refers to rupture of the flexor pollicis longus tendon from attrition caused by a bony spur in the carpal tunnel.

Rural physicians commonly have patients present to the emergency department with injuries to the hand. Occasionally, these injuries involve extensor tendons. Extensor tendon injuries are more common than flexor tendon injuries, due largely to the fact that extensor tendons are less protected and are more superficially located. The strategy used...

We are presenting a case with unusual presentation of the distal cut end of flexor tendon (flexor pollicis longus, FPL). Any patient presenting with laceration anywhere over the hand has to be assessed preoperatively for possibility of injury to either bone or soft tissue underneath. Among soft tissues, tendon, vessels...

Rheumatoid arthritis is the most common underlying etiology of tendon rupture in the hand and wrist and is the usual clinical setting in which the term Vaughan-Jackson syndrome is used. O. J. Vaughan-Jackson's first report of extensor tendon rupture described 2 elderly laborers with degenerative arthritis of the distal radioulnar...
