Biceps is commonly known as the flexor of the elbow and supinator of the forearm ; biomechanically he is also a depressor of the humeral head (Cofield and Sperling, 2010). Some research also says it is a stabilizer of the shoulder joint.
This can especially be an efficient treatment method for younger patients with proximal biceps pathology, to regain adequate strength and endurance and to avoid potential cosmetic deformity in the arm (Rockwood and Matsen, 2009).
For damaged and partially torn long head of biceps tendon; tendon is transposed from its origin on the glenoid of the humerus with screws and anchor; usually a result from a sudden contraction of the biceps to flexion and supination; degeneration caused by improper training, fatigue or compensation for other muscles; mainly occurs in individuals between 40 and 60 years old who do have a previous history of shoulder problems or athletes with heavy over head activities (overuse).
Not seldom, treatment goes hand in hand with SLAP lesion.
