Distal biceps tendon tendinitis is characterized by pain at the front of the elbow due to inflammation of the biceps tendon, usually from friction at a bony prominence (the bicipital tuberosity). The biceps muscle attaches to bone via tendons and is important for bending the elbow and turning the palm up by rotating the wrist. This tends to be an overuse injury, in which symptoms start slowly and gradually get worse.
Frequent Signs and Symptoms
- Pain, aching, tenderness, and sometimes warmth or redness over the front of the elbow
- Pain that is worse with elbow bending or wrist rotation (turning the palm up), especially against resistance (lifting or carrying) or with throwing
- Crepitation (a crackling sound) when the tendon or elbow is moved or touched
Etiology (Causes)
- Strain from sudden increase in amount or intensity of activity
- Direct blow or injury to the elbow (uncommon)
- Overuse or repetitive elbow bending or wrist rotation, particularly when turning the palm up, or with elbow hyperextension
Risk Factors
- Sports that involve contact, throwing sports, gymnastics, weightlifting, bodybuilding, and rock climbing
- Heavy labor
- Poor physical conditioning (strength and flexibility)
- Inadequate warm-up before practice or play
- Injury to other structures of the elbow
- Immobilization of the elbow
