Biceps tendonitis originates on the long head of the biceps brachii at the supraglenoid tubercle in 30% of cases. The main symptom is generally anterior biceps instability, but the disease can also be characterized by chronic anterior shoulder pain which radiates towards the lateral part of the elbow . [ 4 ]
A SLAP lesion (superior labrum, anterior to posterior) is a tear where the glenoid labrum meets the tendon of the long head of the biceps muscle. Symptoms include increased pain with overhead activity, popping or grinding, loss of strength, and trouble localizing a specific point of pain. [3] Because a SLAP lesion involves the biceps, pain and ...
The shoulder joint is muscle-dependent, as it lacks strong ligaments. The primary stabilizers of the shoulder include the biceps brachii on the anterior side of the arm and tendons of the rotator cuff, which are fused to all sides of the capsule except the inferior margin. [5]
The biceps or biceps brachii (Latin: musculus biceps brachii, "two-headed muscle of the arm") is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. Both heads of the muscle arise on the scapula and join to form a single muscle belly which is attached to the upper forearm.
Shoulder anatomy, front view Shoulder anatomy, back view. The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. [3] These muscles are the supraspinatus, infraspinatus, teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during ...
The Latin terms supra and infra meaning above and below respectively refers to the tubercles location in relation to the glenoid cavity. The Latin term glenoid meaning socket or cavity refers to the glenoid cavity. [1] The glenoid tubercles serves as attachment points for the long heads of the biceps brachii and the triceps brachii muscles.
The bicipital groove separates the greater tubercle from the lesser tubercle. [1] It is usually around 8 cm long and 1 cm wide in adults. [1] The groove lodges the long tendon of the biceps brachii muscle, positioned between the tendon of the pectoralis major muscle on the lateral lip and the tendon of the teres major muscle on the medial lip.
A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum (fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade) that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon.
