A finding on ultrasound associated with adhesive capsulitis is hypoechoic material surrounding the long head of the biceps tendon at the rotator interval, reflecting fibrosis. In the painful stage, such hypoechoic material may demonstrate increased vascularity with Doppler ultrasound. [17]
Biceps tenotomy and tenodesis are often performed concomitantly with rotator cuff repair or as separate procedures, and can also cause shoulder pain. Tenodesis, which may be performed as an arthroscopic or open procedure, generally restores pain free motion it the biceps tendon, or attached portion of the labrum, but can cause pain.
The biceps brachii primarily serves to supinate the forearm at the elbow joint. [1] The muscle belly is composed of two heads. The short head is more medial and highlighted in green. The long head is more lateral and highlighted in red. A biceps tendon rupture or bicep tear is a complete or partial rupture of a tendon of the biceps brachii muscle.
Biceps tendinitis or subluxation of the biceps tendon can normally be addressed by palpating the long head of the biceps tendon in the bicipital groove. [2] The patient will exhibit a pain response, snapping or both in the bicipital groove. Pain with no associated popping might indicate bicipital tendinopathy.
The rotator interval is a triangular space in the shoulder that is functionally reinforced externally by the coracohumeral ligament and internally by the superior glenohumeral ligament, and traversed by the intra-articular biceps tendon. On imaging, it is defined by the coracoid process at its base, the supraspinatus tendon superiorly and the ...
Acoustoelastography is an ultrasound technique that relates ultrasonic wave amplitude changes to a tendon's mechanical properties. [ 1 ] See also the page on the acoustoelastic effect .
Bicipital tenosynovitis is tendinitis or inflammation of the tendon and sheath lining of the biceps muscle. It is often the result of many years of small tears or other degenerative changes in the tendon first manifesting in middle age , but can be due to a sudden injury.
Low-intensity pulsed ultrasound (LIPUS) is a technology that can be used for therapeutic purposes. It exploits low intensity and pulsed mechanical waves in order to induce regenerative and anti-inflammatory effects on biological tissues, such as bone, [ 1 ] cartilage, and tendon. [ 2 ]
