Bicipital Groove Retinaculum

Long head of the biceps and humeral bicipital groove.

Bicipital groove retinaculum. Gray s anatomy 2008 online edition and clinical orthopaedic examination magee 2005 propose that the transverse humeral ligament thl runs from the lesser tubercle to the greater tubercle of the humerus covering the long head of biceps with the bicipital groove and acting as a retinaculum assisting the long head of biceps to stay in. The most common traumatic injury to the bicep is to rupture the long head tendon close to where it inserts at the shoulder. Holding the tendon within the groove is the bicipital retinaculum transverse ligament. Biceps tendon tear with loose body in the bicipital groove high grade partial supraspinatus tear subscapularis tendinosis in a 65 year old female.

Dislocation of the long head of biceps tendon is one of the complications of shoulder injury. The tendon is exposed on the anterior shoulder as it passes through the humeral bicipital groove and inserts onto the superior aspect of the labrum of the glenohu. Both heads of the muscle arise on the scapula and join to form a single muscle belly which is attached to the upper forearm. The groove is bordered on three sides by bone the bicipital ridge with a roof covered by the transverse humeral ligament.

When this breaks the tendon flicks in and out depending on load. Biceps brachii long head rupture in a 72 year old male. Search for indirect signs. And the roof is formed by the flexor retinaculum a strong ligament that anteriorly unites the bones.

Bicipital tendinitis or biceps tendinitis is an inflammatory process of the long head of the biceps tendon and is a common cause of shoulder pain due to its position and function. Peroneal tendons and lateral retromalleolar groove due to insufficiency of the proximal retinaculum of the peroneal tendons. Passing between the greater and lesser tubercles is the narrow intertubercular groove sulcus which is also known as the bicipital groove because it provides passage for a tendon of the biceps brachii muscle. While the biceps crosses both the shoulder and elbow joints.

Musculus biceps brachii two headed muscle of the arm sometimes abbreviated to biceps brachii is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. It also transmits a branch of the anterior humeral. The bicipital groove intertubercular groove sulcus intertubercularis is a deep groove on the humerus that separates the greater tubercle from the lesser tubercle the bicipital groove lodges the long tendon of the biceps brachii between the tendon of the pectoralis major on the lateral lip and the tendon of the teres major on the medial lip. The long head of biceps lhb tendon is usually located inferiorly in the bicipital groove held there by the biceps pulley the stabilization role of the transverse humeral ligament is controversial 3 as it moves superiorly it arches through the rotator cuff interval where it is held by a sling.
