Arthroscopic Identification and Management of Hourglass Biceps.

The hourglass biceps is a condition in which the intra-articular portion of the biceps tendon becomes inflamed and hypertrophies relative to the remaining tendon. This condition can be seen in association with rotator cuff and labral pathology and may lead to anterior shoulder pain. Diagnosis requires careful visualization and inspection of the biceps tendon during shoulder arthroscopy, as the presentation may be subtle. Surgical treatment includes tenotomy or tenodesis, depending on patient factors and surgeon preference.
