Calcific Tendinitis of the Proximal Flexor Carpi Radialis in a Throwing Athlete

Grzegorz J Kwiecien et al. J Hand Surg Glob Online. .

Abstract

Flexor carpi radialis tendinitis is a condition that almost exclusively affects the distal aspect of the tendon where it lies in a tight fibro-osseous tunnel. Tendinitis of the proximal aspect of the tendon at its myotendinous junction is extremely rare. Herein, we present a single case of calcific tendinitis of the flexor carpi radialis tendon at its myotendinous junction in a throwing athlete. Diagnostic challenges and treatments are discussed.

Keywords: Athlete; Calcific tendinitis; FCR; Flexor carpi radialis; Injury.
