Definition
The deltopectoral triangle is an anatomical region located at the shoulder, defined by the boundaries of the deltoid muscle laterally, the pectoralis major muscle medially, and the clavicle superiorly.
This triangular area is significant in surgical approaches to the shoulder, particularly the deltopectoral approach, which is commonly used for procedures such as fracture fixation and shoulder replacement.
The cephalic vein serves as a key landmark within the deltopectoral triangle, marking the interval between the deltoid and pectoralis major muscles.
