Anatomical Spaces of the Shoulder
Courtesy: Prof Nabil Ebraheim Important anatomical spaces of shoulder Quadrangular space: Boundaries: Superior: teres minor Inferior: teres major Medial : long head of triceps Lateral : surgical neck of humerus. It contains the axillary nerve and posterior humeral circumflex artery. Axillary nerve can be injured during surgery /fracture/ dislocation surgical dissection should above teres minor […]
Blood Supply of the Proximal Humerus
Courtesy: Prof Nabil Ebraheim ANATOMY OF BLOOD SUPPLY The blood supply to the proximal humerus is derived primarily from branches of the axillary artery. The most important contributor is the anterior humeral circumflex artery. Anterior Humeral Circumflex Artery Arises from the axillary artery. Forms an anastomosis with the posterior humeral circumflex artery. Gives rise […]
