bicepspees

Bicepspees, or the biceps tendon, is the tendon of the biceps brachii muscle. It comprises two proximal tendons that originate from the upper arm and a common distal tendon that attaches near the elbow. The long head of the biceps tendon attaches to the supraglenoid tubercle of the scapula, while the short head attaches to the coracoid process. These proximal tendons join into a single distal tendon that inserts on the radial tuberosity, with an accompanying bicipital aponeurosis extending toward the forearm fascia.

Functionally, the biceps tendon contributes to elbow flexion and forearm supination, especially when the forearm is in a supinated position or the elbow is flexed. It also helps stabilize the shoulder joint during certain movements.

Clinical significance includes injuries such as distal biceps tendon rupture and proximal long head tendinopathy or tear. Distal ruptures commonly occur after a sudden, forceful load and present with acute pain, weakness in forearm flexion and supination, and sometimes a visible bulge known as a popeye deformity. Proximal long head pathology can cause anterior shoulder pain and may be related to impingement or overuse in athletes.

Diagnosis typically involves physical examination augmented by imaging, with ultrasound or magnetic resonance imaging (MRI) used to assess tendon integrity. Treatment depends on the injury and patient factors: partial tears may be managed nonoperatively, while complete distal tendon ruptures often require surgical repair to restore strength and function. Postoperative rehabilitation is important for recovery.
