Biceps tendon tears can result from various factors, including acute injuries and chronic overuse.
Common causes of biceps tendon tears:
Acute Trauma: A sudden forceful movement or traumatic event can cause a tear in the biceps tendon. This can occur during activities such as lifting heavy objects, participating in contact sports, or falling onto an outstretched arm. Direct impact to the elbow or shoulder region can also lead to tendon tears.
Repetitive Overuse: Chronic overuse or repetitive stress on the biceps tendon can weaken the tendon over time, making it more susceptible to tears. This is common in individuals who engage in activities or occupations that involve repetitive arm motions, such as weightlifting, throwing sports (e.g., baseball, javelin), overhead work (e.g., painting, construction), or activities that require frequent lifting or pulling.
Age-related Degeneration: As people age, the tendons in the body naturally become less elastic and more prone to degeneration. This can make the biceps tendon more susceptible to injury, especially in individuals over the age of 40 or those with pre-existing degenerative changes in the tendon.
Poor Lifting Technique: Improper lifting techniques, such as lifting objects with excessive force or using incorrect body mechanics, can place excessive strain on the biceps tendon and increase the risk of injury.
Previous Injuries: Patients who have previously experienced injuries to the shoulder or elbow joint, such as rotator cuff tears, shoulder impingement syndrome, or tendinitis, may be at a higher risk of developing biceps tendon tears due to weakened or compromised tendon structures.
Steroid Injections: Prolonged or frequent use of corticosteroid injections in the shoulder joint to manage inflammation or pain can weaken the tendon and make it more susceptible to tears.
Underlying Medical Conditions: Certain medical conditions, such as rheumatoid arthritis, gout, or hyperparathyroidism, can affect the health of the tendons and increase the risk of tendon tears.
Anabolic Steroid Use: Misuse or abuse of anabolic steroids, which are often used to enhance athletic performance or promote muscle growth, can weaken tendon structures and increase the risk of tears.
It’s essential to note that while these factors can contribute to the development of biceps tendon tears, the exact cause may vary from patient to patient. Seeking prompt medical evaluation and appropriate treatment is crucial for a patient experiencing symptoms of a biceps tendon tear to prevent further damage and facilitate recovery.
