A patient presented with simultaneous left-sided distal biceps tendon rupture and a right-sided distal biceps complete musculotendinous junction tear after lifting a motorcycle. The left upper extremity was treated operatively with acute repair, and the right upper extremity was managed nonoperatively. At the final follow-up, the patient reported full strength and motion with Disabilities of the Arm, Shoulder and Hand (DASH) and QuickDASH scores of 14.2 and 20.5, respectively.
We report the first known case of simultaneous bilateral distal biceps injuries occurring at different anatomic locations. One side was operatively managed, whereas the other underwent conservative treatment. Both treatments resulted in a satisfactory patient outcome.
