Rupture of the flexor pollicis longus tendon after volar fixed-angle plating of a distal radius fracture: a case report.

摘要

We report a case of complete rupture of the flexor pollicis longus tendon 13 months after volar fixed-angle plating of a distal radius fracture. Tendon disruption was associated with a prominent distal volar lip of the plate. The plate was placed at the volar distal lip of the radius, at the location recommended by the manufacturer. Most previous reports of flexor tendon ruptures after volar plating of distal radius fractures have been in improperly placed plates, custom-made plates that were later taken off the market, or in physiologically abnormal tendons. This may be a unique case of flexor pollicis longus rupture with a currently commercially available volar fixed-angle plate, placed at the site recommended by the manufacturer, in a patient without other predisposition to tendon rupture.
