The term ‘surgical neck of the humerus’ refers to a specific area of the humerus bone, located just below the shoulder joint where the bone narrows. This is the transition zone between the head of the humerus, which articulates with the shoulder blade, and the shaft of the humerus, the long part of the bone that extends down the arm.
The reason it’s called the ‘surgical neck’ is primarily due to its significance in surgical procedures. This area is a common site for fractures, particularly in older adults who may suffer from falls. Because of its susceptibility to injury and the potential complications that can arise from a fracture in this region, surgeons often perform procedures here, such as fixations or replacements.
Furthermore, the surgical neck is in proximity to important anatomical structures, including crucial blood vessels and nerves, making it a focal point for surgical interventions. Thus, the name reflects both the anatomical location and its relevance in medical practice.
