Trigger Points in the Biceps are associated with most painful shoulder conditions including frozen shoulder.
Biceps tendonitis is extremely common. It occurs in the long head of the biceps tendon as it runs on the anterior aspect of the humerus between the attachments of the supraspinatus (greater tuberosity) and subscapularis (lesser tuberosity).
The biceps function to flex the elbow joint, and supinate the forearm. It also (weakly) flexes the arm at the shoulder joint. It has been described as the muscle that puts in the corkscrew and pulls out the cork!
Problems with the biceps tendon can result from impingement or from inflammation and can also occur secondary to, or as a result of, compensation for other shoulder disorders.
Diagnosis can often be difficult because of the complexity of the shoulder, and because it is common for several different problems to exist in the same shoulder at the same time. This can create a sometimes confusing clinical picture.
Biceps injuries can occur for a whole host of reasons but are definitely more common among those who engage in frequent pulling, lifting, reaching or throwing, and with repetitive overhead activity.
Trigger Points and the Biceps
Biceps tendinitis is almost always associated with trigger points. However, these biceps trigger points are also commonly asscoiated with non-specific anterior shoulder pain (usually with decreased arm extension), and play a key role in frozen shoulder syndrome.
The LHB tendon is unique in that it inserts inside the capsule of the joint to attach directly to the socket bone (lower glenoid fossa). This means, inflammation that starts lower down the tendon can track upwards directly into the ball and socket joint causing havoc; as is the case in frozen shoulder syndrome.
Trigger points in the biceps can be quite stubborn and require a certain amount of skill and experience to treat effectively, although a little bit of self-help can often make a difference.
