The surgical neck of the humerus is a bony constriction at the proximal end of shaft of humerus. It is situated distal to the greater tubercle and lesser tubercle , and proximal to the deltoid tuberosity .
English: The anatomical neck is the groove that surrounds the articular surface of the head of the humerus. This is where the joint capsule is attached. The surgical neck however, is a segment present inferior to the humeral head. This acts as a connection between the head and the shaft of the humerus.
The anatomical neck divides the head of the humerus from the greater and lesser tubercles of the humerus. It gives attachment to the capsular ligament of the shoulder joint except at the upper inferior-medial aspects.
The most common location of proximal fractures is at the surgical neck of the humerus. [3] Incidence of proximal fractures increases with age, with about 75% of cases occurring among people over the age of 60. [11] In this age group, about three times as many women as men experience a proximal fracture. [23]
The anatomical neck (collum anatomicum) is obliquely directed, forming an obtuse angle with the body. It is best marked in the lower half of its circumference; in the upper half it is represented by a narrow groove separating the head from the tubercles. The line separating the head from the rest of the upper end is called the anatomical neck.
The anatomic neck of the scapula is the slightly constricted portion which surrounds the head and is more distinct below and behind than above and in front. The surgical neck of the scapula passes directly medial to the base of the coracoid process.
