During a biceps tenodesis, where is the biceps tendon reattached?

In a biceps tenodesis procedure, the biceps tendon is reattached to the humerus. This surgical intervention is often performed to relieve shoulder pain associated with biceps tendinopathy or to address instability issues related to the long head of the biceps tendon.

By reattaching the tendon to the humerus, typically at the bicipital groove, the procedure aims to minimize the biomechanical load on the shoulder joint while allowing for preservation of function. This location is strategically chosen to restore the function of the biceps muscle while alleviating the pain that may originate from the tendon’s original attachment point at the glenoid labrum, which is notorious for degenerative changes.

The other options involve incorrect sites for tendon reattachment. The labrum is where the biceps originally attaches, while the ulna and clavicle are not anatomical locations associated with the biceps tendon’s function or typical surgical management. Thus, the correct choice reflects the objective of re-establishing a stable and functional positioning for the tendon and the muscle it serves.
