What is active insufficiency of the biceps tendon?

Active insufficiency of the biceps tendon occurs when the biceps tendon is unable to generate sufficient force to flex the elbow against gravity when the forearm is supinated, despite being able to do so when the forearm is pronated. This is due to the fact that the biceps tendon passes over the radial tuberosity, which is located on the lateral aspect of the elbow joint. When the forearm is supinated, the radial tuberosity compresses the biceps tendon, making it more difficult for it to generate force.

Active insufficiency of the biceps tendon can be caused by a number of factors, including:

* Damage to the biceps tendon: This can occur as a result of trauma, such as a fall or a motor vehicle accident.

* Inflammation of the biceps tendon: This can be caused by a variety of conditions, such as arthritis or tendinitis.

* Muscle weakness: This can occur as a result of a variety of conditions, such as aging, malnutrition, or certain medical conditions.

Active insufficiency of the biceps tendon can cause a number of symptoms, including:

* Pain in the elbow

* Weakness in the elbow

* Difficulty flexing the elbow

* A catching or snapping sensation in the elbow

If you are experiencing any of these symptoms, you should see a doctor to be diagnosed and treated. Treatment for active insufficiency of the biceps tendon may include:

* Rest

* Ice

* Compression

* Elevation

* Physical therapy

* Surgery
