Distal Biceps Tendonitis Causes, Symptoms & Treatment

Overview

The distal biceps tendon attaches the biceps muscle to the elbow bone and can become inflamed and weakened due to repetitive strain, overuse, or improper lifting techniques. This condition, known as distal biceps tendonitis, often results in pain, stiffness, and limited movement in the elbow, particularly during bending or lifting motions.

What causes Distal Biceps Tendonitis?

Distal biceps tendonitis most often develops from repetitive overuse or activities that put constant strain on the tendon connecting the biceps to the elbow. It frequently occurs in athletes and workers who perform repetitive pulling, twisting, or lifting motions. Lifting heavy objects with improper form or a bent arm increases the risk of irritation and inflammation.

• How the injury occurs: This injury usually develops gradually due to repetitive microtears in the tendon fibers. Over time, the tendon becomes inflamed and weakened, leading to pain, stiffness, and reduced strength during elbow flexion or rotation.
• Common Everyday Causes: Distal biceps tendonitis can also affect manual laborers, mechanics, or individuals who frequently lift, carry, or twist heavy objects at work. Even repetitive household tasks like gardening, lifting groceries, or cleaning can contribute if done with poor arm mechanics.

Biceps tendonitis is common in these sports:

• Weightlifting: Repeated heavy lifting and curling movements can overwork the tendon, especially with poor technique.
• Bodybuilding: Constant upper arm training and muscle fatigue can lead to tendon strain over time.
• Gymnastics: High-tension routines like bar work or rings stress the biceps during pulling and holding positions.
• Bowling: The repetitive swinging motion of the arm can irritate the tendon near the elbow.
• Baseball: Frequent throwing and batting motions create strain from repeated elbow flexion and extension.
• Softball: Like baseball, repetitive arm movements and fast throws can inflame the biceps tendon.
• Tennis: The forehand and serve place repetitive stress on the tendon during racquet acceleration.
• Golf: The swinging motion and grip pressure during play can irritate the tendon, especially with overuse.

Symptoms

Distal biceps tendonitis can cause gradual pain and discomfort in the lower part of the upper arm near the elbow. The symptoms may start mild but can worsen with repetitive use or intense physical activity. Common signs include:

• Pain in the front of the elbow: Often felt during activities like throwing, lifting weights, or performing sports that involve repetitive arm motion.
• Stiffness and soreness: A tight or achy feeling may develop in the front of the bicep close to the elbow, especially after exercise or prolonged use.
• Tenderness or mild swelling: The area around the tendon may feel sore to the touch, with occasional puffiness or localized inflammation.
• Dull, worsening pain with resistance: Pain often intensifies when bending the arm against resistance or twisting the forearm, such as using a screwdriver, turning a doorknob, or opening a jar.

Non-operative treatment

Distal biceps tendonitis is generally managed using conservative, non-surgical methods. The first step involves resting the arm and avoiding activities that strain the biceps, such as lifting, pulling, or repetitive twisting. Applying ice to the affected area for 10 minutes every hour during the first few days can help reduce swelling and inflammation.

Your doctor may recommend nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or aspirin, to relieve pain and decrease inflammation in the lower biceps tendon. Once pain subsides, physical therapy is often introduced to restore flexibility, improve strength, and promote proper arm movement. A gradual return to activity is essential to prevent re-injury and ensure complete recovery.

Surgical Treatment

Surgery is rarely required for distal biceps tendonitis, as most cases respond well to conservative care. However, if the tendon becomes completely ruptured or there is significant loss of strength and function in the elbow, surgical repair may be necessary. The procedure typically involves reattaching the torn tendon to its proper position on the bone to restore stability and movement.
