Arcuate Artery Bicipital Groove
The bicipital groove lies between the greater and lesser tuberosities and serves as a pathway for the long head of the biceps as it traverses from its.
Arcuate artery bicipital groove. The anterior humeral circumflex artery then travels horizontally behind the coracobrachialis muscle towards the bicipital groove intertubercular sulcus where its principal branch the arcuate artery ascends along the lateral portion of the groove and supplies the humerus at the level of the greater tuberosity. The arcuate artery ascends on the lateral border of the intertubercular groove and enters the bone at the level of the greater tuberosity its intraosseous continuation follows a curved posteromedial path distal to the. C and d axial and coronal. Arcuate artery is the interosseous continuation of ascending branch of anterior humeral circumflex artery and penetrates the bone of the humeral head.
Main arterial supply to the humeral head is from a branch of the anterior humeral circumflex artery the arcuate artery. A and b axial and coronal microfocus ct views of the proximal humerus of individual 1 clearly showing the arcuate artery s entrance into the superolateral aspect of the bicipital groove bg and its intraosseous course into the greater tuberosity gt with its medially migration toward the humeral head hh. 3 5 cm of the lhbt can be pulled into the joint and inspected during arthroscopy allowing only partial visualization of the tendon in the groove 48. Lesions within the distal bicipital groove and beyond will not be seen.
Sulcus bicipitalis lateralis ta sulcus bicipitalis radialis want to thank tfd for its existence. Classical teaching was the arcuate artery from anterior humeral circumflex a running along lateral side of bicipital groove. Bony congruency labrum capsule ligaments negative pressure. The groove along the lateral side of the arm separating the biceps brachii and brachialis muscles.
Provides 35 of blood supply to. 18 injury to the arcuate artery can result in osteonecrosis of the humeral head. Collateral branches can permit humeral head perfusion despite complete ligation of the arcuate artery. Humeral circumflex artery courses along bicipital groove terminal branch arcuate artery post.
List the static and dynamic restraints. Anterolateral ascendan artery provides primary vascular supply branch of ant. Humeral circumflex artery posterior gt anastomosis with arcuate artery anterolateral ascendan branch ant. Vessel runs parallel to lateral aspect of tendon of long head of biceps in the bicipital groove.
