The document discusses biceps tendon ruptures, including the anatomy of the biceps muscle and different types of ruptures. Proximal ruptures can be traumatic or degenerative and are often associated with rotator cuff tears. Surgical management of proximal ruptures involves long head of biceps tenodesis, though the optimal site and technique are debated. Distal ruptures occur when the tendon is loaded during contraction and early repair is recommended for active individuals with distal ruptures.
