What Is a Biceps Tendon Rupture?
A rupture of the biceps tendon occurs when one of the tendons that attaches the biceps muscle to the shoulder or elbow tears partially or completely. The biceps tendon can rupture at the shoulder (proximal rupture) or at the elbow (distal rupture), depending on where the tendon separates from the bone.
When the tendon tears, the biceps muscle may retract toward the shoulder, sometimes creating a visible bulge in the upper arm commonly called a “Popeye” deformity. This injury can lead to pain, weakness, and difficulty using the arm.
Symptoms of a Biceps Tendon Rupture
Common symptoms include:
- Sudden sharp pain in the upper arm or elbow
- A popping or tearing sensation at the time of injury
- Bruising or swelling in the arm
- Weakness in the shoulder or elbow
- Difficulty rotating the forearm
- Visible bulge in the upper arm (“Popeye” muscle)
- Tenderness along the biceps
- Reduced arm strength
Patients often report hearing or feeling a “pop” followed by pain and weakness.
Common Causes
Biceps tendon ruptures typically occur due to sudden stress on the tendon or long-term degeneration. Common causes include:
- Lifting heavy objects
- Sudden pulling motion
- Sports injuries
- Falls on an outstretched arm
- Repetitive overhead activity
- Degenerative tendon changes
- Weightlifting injuries
- Previous shoulder or elbow problems
Distal biceps tendon tears commonly occur during forceful lifting when the elbow is forced straight while the muscle contracts.
How Biceps Tendon Ruptures Are Diagnosed
Diagnosis begins with a physical examination of the arm and shoulder. Your orthopedic specialist will evaluate strength, range of motion, and visible deformity. Imaging studies may include:
- X-rays to rule out fractures
- MRI to confirm tendon rupture
- Ultrasound in select cases
In many cases, the injury can be identified based on history and physical exam findings.
Biceps Tendon Rupture Treatment Options
Non-Surgical Treatment
Some biceps tendon ruptures can be treated without surgery. Conservative treatment may include:
- Rest and activity modification
- Ice and anti-inflammatory medication
- Sling support
- Physical therapy
- Strengthening exercises
Proximal biceps tendon ruptures are often treated non-surgically, especially in less active individuals.
Surgical Treatment
Surgery may be recommended for active individuals or distal tendon ruptures. Surgical options may include:
- Biceps tendon repair
- Tendon reattachment to bone
- Biceps tenodesis
- Reconstruction procedures
Distal biceps ruptures often require surgical repair due to loss of forearm strength.
Recovery After Biceps Tendon Rupture Treatment
Recovery depends on the severity and treatment approach. Non-surgical treatment may require several weeks of rest followed by rehabilitation. After surgical repair, patients typically wear a sling initially and begin structured therapy to restore strength and motion. Full recovery may take several months.
When to See an Orthopedic Specialist
You should seek evaluation if you experience:
- Sudden upper arm pain
- A popping sensation in the arm
- Visible bulge in the biceps
- Weakness in the arm
- Difficulty lifting or rotating the arm
- Bruising after injury
Early evaluation helps determine whether surgical repair is recommended.
