Figure A shows a distal radius fracture treated with a volar locked plate. Historically, distal radius fractures treated with dorsal plates were notorious for extensor tendon irritation with some cited rates as high as 50%. In the reference by Drobetz et al, they reviewed 50 fractures treated with a volar locked plate. They noted that in 6 (12%) of cases that there was rupture of the flexor pollicis longus (FPL) at a mean of 10 months post operatively. The second reference by Douthit is a retrospective review of 46 fractures treated with a volar locked plate. Excellent initial and maintenance of reduction was noted in 85% of cases, but FPL rupture occurred in 2 patients. Prominent plates and sharp screws were cited as reasons for tendon rupture.
