Clinically Relevant Anatomy and Biomechanics of the Proximal Biceps.

The biceps-labral complex represents the shared anatomic and clinical features of the biceps and labrum. It has 3 clinically relevant zones: inside, the superior labrum and the biceps anchor; junction, the intra-articular portion of the long head of the biceps tendon and its stabilizing pulley; and bicipital tunnel, the extra-articular long head of the biceps tendon from the articular margin through the subpectoral region and its fibro-osseous confinement. By embracing this more comprehensive understanding of the anatomy, pathoanatomy, and functional implications, clinicians can proceed with greater confidence and can more accurately select patient-specific surgical techniques.
