Diagnosis of biceps tendon dislocation by kinematic magnetic resonance imaging.

Biceps tendon dislocation is an uncommon condition that may be overlooked due to its association with more common shoulder pathology. Diagnosis may be further obscured by the difficulty of palpating the biceps tendon in a muscular or obese patient. We present a patient with a dislocating biceps tendon in which the diagnosis was confirmed by kinematic MRI.
