Flexor pollicis longus injury after corrective osteotomy of distal radius malunion with volar fixed-angle plating: case report and review literature of the flexor tendon injuries after volar plating.

Flexor tendon injury is a potential complication after volar plating of distal radius fracture. This article reports a case of flexor pollicis longus tendon rupture after corrective osteotomy of a distal radius malunion with volar fixed-angle plating. Thirty-three cases of flexor tendon injuries after fixed-angle volar plating and eleven cases of flexor tendon injuries after non-fixed-angle volar plating were also reviewed. The clinical presentation, injured tendons, type of the plate, causes of the injuries and preventions of this complication were discussed.
