Biceps Tendon Rupture: Causes, Symptoms, and Treatment

What kind of doctor treats Biceps Tendon Rupture?

An orthopedic surgeon, a doctor who treats bone, joint, and tendon injuries, usually cares for a ruptured biceps tendon. A primary care doctor can do the first exam. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What is a biceps tendon rupture?

Tendons are strong cords that attach muscles to bones. The biceps muscle is in the front of your upper arm. Tendons attach it to bones in the shoulder and elbow. When one of these tendons tears all the way through, the muscle pulls away from the bone.

Tears can be partial or complete. A complete tear detaches the tendon from the bone. Tears at the shoulder are common and often need only simple treatment. Tears at the elbow are uncommon, happen mainly in men over 30, and tend to cause more arm weakness.

Symptoms

Common signs include:

  • Sudden, sharp pain in the upper arm, or severe pain at the elbow.
  • Often a pop or snap when the tendon tears.
  • Bruising of the upper arm toward the elbow, or in the elbow and forearm.
  • Weakness in the shoulder, elbow, or forearm.
  • Trouble turning the hand palm up (a motion called supination).
  • A bulge in the upper arm, sometimes called a "Popeye" deformity, when the torn muscle bunches up.

Causes and who gets it

The two main causes are injury and overuse. A fall on an outstretched arm or lifting something too heavy can tear the tendon. Many tears come from slow wearing down and fraying of the tendon over time, which happens naturally with age and is made worse by repeating the same motions. Risk rises with age, heavy overhead work or sports like swimming and tennis, smoking, and corticosteroid medicines, which can weaken tendons.

How doctors diagnose it

The doctor will ask how the injury happened, then examine the arm. They may feel for a gap in the tendon, test how strongly you can turn your palm up, and compare it with your other arm. An often clear sign is the muscle bunching up near the elbow or shoulder. Imaging helps confirm the tear: X-rays cannot show tendons but can rule out other problems, ultrasound can show the pulled-back tendon, and MRI scans show both partial and complete tears.

Treatment

Treatment depends on where the tear is and how much arm strength you need.

  • Nonsurgical care for many shoulder tears: rest, avoiding heavy lifting and overhead activities, ice to keep down swelling, and anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen for pain.
  • Physical therapy: flexibility and strengthening exercises restore movement and strength.
  • Surgery: many shoulder tears never need it. Elbow tears are different: surgery to reattach the tendon is needed to regain full arm strength, and it works best in the first 2 to 3 weeks after injury. People who are older, less active, or cannot do the rehabilitation may choose nonsurgical care instead.

After surgery the arm may rest in a sling or cast, and physical therapy follows. The tendon takes more than 3 to 4 months to fully heal, so heavy lifting should wait several months.

When to see a doctor

See a doctor promptly after a sudden pop, sharp pain, or bulge in the arm. A tear near the elbow is more likely to need surgery, and repair works best within the first few weeks, so do not wait. Get care right away if arm weakness stops you from working or doing daily activities like bathing or dressing.

How a direct primary care or concierge doctor fits in

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can examine the injured arm, order imaging, and refer you to an orthopedic surgeon when surgery may help. They can also follow your recovery and help manage pain medicines.

Common questions

Will my arm still work after a tear?

Usually yes. Other muscles let you bend the elbow fairly well even without the tendon. But strength drops, mainly in twisting the forearm palm up, where it can fall by about 30 to 40 percent after an elbow tear.

Does a shoulder tear always need surgery?

No. Long head tears at the shoulder rarely need surgery. Most people return to their activities with simple treatment. The biceps has two attachments at the shoulder, and the second one rarely tears.

Why does my arm look bulged?

When the tendon tears, the muscle is no longer held tight. It bunches up into a bulge near the elbow or shoulder. This is often called a "Popeye" deformity.

How long is recovery after surgery?

The tendon needs more than 3 to 4 months to fully heal. Light activities can start soon, but heavy lifting should wait several months. Most people regain full range of motion and near full strength.
