Biceps Tendon Rupture at the Shoulder
A sudden pop, bruising, or a change in the biceps contour may indicate a tendon tear. The location of the tear changes the treatment.
A rupture near the shoulder
The long head of the biceps can tear near its attachment in the shoulder. The muscle may sit lower in the arm, creating a “Popeye” appearance. Symptoms can include bruising, cramping, and weakness, although many people retain useful function because the biceps has another attachment at the shoulder.
An elbow tear is a different problem
A tear near the elbow—the distal biceps—is not treated the same way as a long-head rupture at the shoulder. New bruising or a gap near the elbow with loss of strength, particularly turning the palm upward, needs prompt evaluation. Do not assume that a visible biceps change is harmless.
Check the rest of the shoulder
Biceps symptoms may coexist with a rotator cuff tear or other shoulder disease. The examination assesses motion, strength, tenderness, and the location of the injury. Ultrasound or MRI may be used when the diagnosis or associated tendon damage is uncertain.
Does a shoulder-level rupture require surgery?
Not always. Many proximal long-head ruptures are managed without an operation. Persistent cramping, pain, functional limitations, activity demands, or associated shoulder pathology may lead to a discussion of surgery such as tenodesis.
The choice should reflect symptoms and goals rather than appearance alone. If a procedure is performed, lifting and resisted elbow use follow a specific healing plan.
What to bring to the visit
Note when the pop or bruising occurred, where it hurts, what tasks are difficult, and whether you had shoulder pain before the event. Avoid heavy lifting until the injury has been assessed.
