It gives attachment to the capsular ligament of the shoulder joint except at the upper inferior-medial aspects. 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 of the humerus from the two tubercles, the greater tubercle and the lesser tubercle.
The humerus (/ ˈ h juː m ər ə s /; pl.: humeri) is a long bone in the arm that runs from the shoulder to the elbow.It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections.
Most growth plate fractures heal without any lasting effects. [1] Rarely, bridging bone may form across the fracture, causing stunted growth and/or curving. [1] In such cases, the bridging bone may need to be surgically removed. [1] A growth plate fracture may also stimulate growth, causing a longer bone than the corresponding bone on the other ...

There are three locations that humerus fractures occur: at the proximal location, which is the top of the humerus near the shoulder, in the middle, which is at the shaft of the humerus, and the distal location, which is the bottom of the humerus near the elbow. [9] Proximal fractures are classified into one of four types of fractures based on ...
A proximal humerus fracture is a break of the upper part of the bone of the arm . [3] Symptoms include pain, swelling, and a decreased ability to move the shoulder . [ 1 ] Complications may include axillary nerve or axillary artery injury.
The greater tubercle of the humerus is the outward part the upper end of that bone, adjacent to the large rounded prominence of the humerus head. It provides attachment points for the supraspinatus, infraspinatus, and teres minor muscles, three of the four muscles of the rotator cuff, a muscle group that stabilizes the shoulder joint.
