Gouty Tenosynovitis of the Distal Biceps Tendon Insertion Complicated by Partial Rupture: First Case and Review of the Literature.

Abstract

<b>Background:</b> Given the appreciable prevalence of gout, gout-induced tendon ruptures in the upper extremity are extremely rare. Although these events have been reported only 5 times in the literature, all in patients with a risk factor for or history of gout, they have conspicuously never been diagnosed in the shoulder or elbow. <b>Methods:</b> A 45-year-old, right-hand-dominant man with a history of gout presented with pain in his right anterior elbow and weakness in his forearm after a trivial injury. <b>Results:</b> Here, we report the first case of gouty tenosynovitis of the distal biceps tendon insertion complicated by partial rupture, a composite diagnosis supported by both intraoperative and histological observations. <b>Conclusions:</b> In patients who are clinically diagnosed with biceps tendon rupture and have a history of gout, it is important to consider the possibility of a gout-related pathological manifestation causing or simulating tendon rupture.
