It is the groove where the long head of biceps tendon runs between the greater and lesser tubercles below the humeral head before inserting into the superior glenoid rim. The lateral bicipital groove is seen on the lateral aspect of the upper arm, and is formed by the same anatomical structures as the medial groove.
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.
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.
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.
The bicipital aponeurosis originates from the distal insertion of the biceps brachii, and inserts into the deep fascia of the forearm. [1] The biceps tendon inserts on the radial tuberosity, and the bicipital aponeurosis lies medially to it. [2] It reinforces the cubital fossa, helping to protect the brachial artery and the median nerve running ...
The artery runs medial to the biceps tendon. The brachial pulse may be palpated in the cubital fossa just medial to the tendon. The area just superficial to the cubital fossa is often used for venous access in procedures such as injections and obtaining samples for blood tests. A number of superficial veins can cross this region.
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 bicipitoradial bursa is a bursa located between the distal tendon of the biceps brachii muscle and the anterior part of the tuberosity of the radius. [1] It partially or completely wraps around the biceps tendon. It ensures frictionless motion between the biceps tendon and the proximal radius during pronation and supination of the forearm ...
