Delayed flexor pollicis longus tendon rupture following sharp trauma
Discussion:
Late rupture is one of several possible complcations after traumatic partial laceration of the FPL tendon1.
Post-traumatic FPL tendon ruptures must be differentiated from Mannerfelt syndrome, referring to attrition rupture of the FPL tendon caused by bony spurs at the scaphoid or in the carpal tunnel, a typical complication in rheumatoid arthritis.
