Definition
The surgical neck is a narrowed section just below the head and tubercles of the humerus bone, where it transitions to the shaft. This area is prone to fractures and is a common site for surgical intervention in case of injury.
The longest bone in the arm that runs from shoulder to elbow, connecting with muscles and joints to facilitate movement.
Fracture: A break in bone integrity, which can range from small cracks to complete breaks; fractures in areas like the surgical neck require careful medical attention.
Tubercles of Humerus: Two projections near the head of the humerus (greater and lesser tubercle) involved in muscle attachment and arm movement mechanics
