Extensor pollicis longus dysfunction associated with non-united fracture of the trapezium.

Author information

Gisborne Hospital, Gisborne, New Zealand.


A 26 year old man was referred to us with extensor pollicis longus dysfunction (EPL), and investigation revealed a fracture of the trapezium (left) and carpo-metacarpal joint dislocation of the thumb. Operative exploration revealed mechanical displacement of the tendon secondary to fracture dislocation of the trapezium as the cause for EPL dysfunction. The lesion was managed with an open reduction and screw fixation resulting in good functional outcome.
