Delayed Rupture of the Flexor Pollicis Longus After Volar Plating for a Distal Radius Fracture: A Case Report.

Distal radius fractures account for 18 percent of all fractures in the elderly age group. It is estimated that the yearly cost of treatment for distal radius fractures approaches $240 million. The frequency of fractures will continue to increase with the aging population. The operative treatment of distal radius fractures has changed dramatically with the advent of the fixed-angle volar plate. Volar plating allows stable internal fixation which permits early return of function. A common and serious complication of volar plating of distal radius fractures is rupture of the flexor pollicis longus tendon. We report a case of a late rupture of the flexor pollicis longus tendon six years following plating of a distal radius fracture. The pathology and treatment options for flexor tendon ruptures are discussed. Guidelines for patient surveillance following distal radius plating are reviewed.
