What Is a biceps tendon rupture?

A biceps tendon rupture is a tear in the tendon connecting your biceps muscle to your shoulder or elbow, causing sudden pain, weakness, and sometimes a visible change in your arm's shape.

Living with biceps tendon rupture

A biceps tendon rupture can happen quickly and unexpectedly, often during lifting, a sudden reach, or a fall. Depending on where the tear occurs, it may affect your ability to lift, carry, turn your palm upward, or even get dressed comfortably. Most ruptures happen in the shoulder area and affect men in their 40s and 50s, though anyone can experience one.¹

The condition is more common than many people realize, accounting for roughly 16% of all acute tendon injuries seen in emergency departments across the United States. [3] While a biceps tendon rupture sounds serious, many people make strong recoveries with the right care, and most are able to return to their usual activities over time.

What are the symptoms of a biceps tendon rupture?

Symptoms vary depending on whether the rupture is at the shoulder or the elbow, and whether it is a partial or complete tear. Common experiences include:

• A sudden, sharp pain at the front of the shoulder or elbow, often with a popping sensation
• Bruising and swelling in the upper arm or elbow crease in the hours after injury
• A visible bulge or lump in the upper arm, sometimes called a Popeye sign, caused by the muscle bunching upward
• Weakness when bending the elbow or turning the palm upward (supination)
• Difficulty with everyday tasks like opening a door, carrying a bag, or screwing in a lightbulb
• Ongoing aching or cramping in the biceps muscle, especially with use

What causes a biceps tendon rupture?

Most biceps tendon ruptures happen when a heavy or unexpected force is applied to the arm. This can occur during weightlifting, catching a falling object, or any activity that places sudden intense effort on the biceps.¹ Over time, factors like smoking, obesity, and the use of certain medications such as corticosteroids can weaken tendon tissue and raise the risk.² Anabolic steroid use has also been associated with upper-body tendon ruptures, likely because muscle growth outpaces tendon strength.¹⁰

Common risk factors include:

• Smoking, which reduces blood flow to the tendon and is associated with a 7.5-times greater risk of distal rupture²
• Heavy manual labor or high-load lifting activities
• Use of corticosteroids (oral or injected) or anabolic steroids
• Elevated body weight, which places greater movement demands on tendons
• Pre-existing arm, elbow, or rotator cuff problems at the shoulder

When should I see a doctor for biceps tendon rupture?

If you have heard or felt a pop in your shoulder or elbow and notice sudden pain, bruising, or arm weakness, it is important to see a doctor promptly. For complete distal (elbow) tears in particular, prompt evaluation matters because surgery is most effective when performed within the first few weeks of injury. [4] You should seek care urgently if you also experience numbness or tingling in your hand, cannot move your elbow or forearm normally, or have significant swelling that is worsening.

How is a biceps tendon rupture treated?

Treatment depends on where the rupture occurred, whether it is partial or complete, and how active you are. For most proximal ruptures (near the shoulder), conservative care works well. For complete distal (near the elbow) ruptures in people who use their arm heavily, surgery is typically recommended to restore strength.⁵

Typical approaches include:

• Rest and ice during the acute phase to manage pain and swelling
• Anti-inflammatory medication known as NSAIDs (nonsteroidal anti-inflammatory drugs like ibuprofen) to reduce discomfort in the early stages
• Physical therapy to restore range of motion, rebuild strength, and support function
• Surgery is reserved for tendon repair to reattach the bicep to the bone and for complete distal near-elbow ruptures
• In some instances, surgery can be considered when conservative care does not restore adequate strength or function

Most people who receive appropriate treatment, whether surgical or non-surgical, are able to return to daily activities and many return to sport. Recovery typically takes 3 to 6 months depending on the extent of the injury and the treatment path.⁸

Clinical insight

Surgery is often not required for biceps tendon ruptures, but there is a strong exception: for complete distal near-elbow biceps tendon ruptures in physically active people, surgery within the first four weeks of injury produces the best outcomes with the fewest complications. Waiting longer does not necessarily prevent surgery from being successful, but it can make the procedure more complex. ^{5 4}
