Humeral Head Anatomy

The humerus is the only bone found in the anatomical arm. The radius and ulna bones are found in the forearm.

Humeral head anatomy. The proximal end is round and has an articular head. The bottom of the humerus touches the top of the radius and ulna which joins the upper arm with the lower arm. The humeral head average offset from the shaft is 3 mm posterior and 7 mm medial.

The most superior portion of the humeral head is typically 8 mm above the height of the greater tuberosity 2. It is directed upward medialward and a little backward and articulates with the glenoid cavity of the scapula to form the glenohumeral joint shoulder joint. The head of the humerus forms the ball of the ball and socket shoulder joint with the glenoid cavity of the scapula acting as the socket.

The distal end is irregular in shape. Minimally displaced surgical and anatomic neck fractures. The humerus articulates proximal region by the scapula at the shoulder joint and radius and distal region with ulna at the elbow joint.

Humeri is a tubular bone of the arm that articulates proximally at the shoulder with the glenoid of the scapula and distally at the elbow with the radius and ulna. The top of the humerus joins with an area called the glenoid fossa on the scapula or shoulder blade. Additional variables to consider.

Most proximal humerus fractures can be treated nonoperatively including. It consists of a proximal end a shaft and a distal end all which contain important anatomical landmarks. Greater tuberosity fracture displaced 5mm.

In anatomy the arm is the part of the upper extremity from the elbow to the shoulder. Bony landmarks muscle attachment the humerus is described as having a proximal region shaft and distal region. The humerus is the longest and largest bone of the upper limb.

Fractures in patients who are not surgical candidates. The rounded shape of the head of the humerus allows the humerus to move in a complete circle circumduction and rotate around its axis at the shoulder joint. The humerus articulates with the scapula proximally at the glenohumeral joint so it participates in the movements of the shoulder.

The shaft connects both the proximal and distal ends. The humerus is the largest bone of the upper limb and it has two ends and a shaft. Humeral head the head caput humeri is nearly hemispherical in form.

The proximal humeral articular surface is a segment of a sphere that measures from 37 to 57 mm in diameter 5. The humerus is the largest bone in the entire upper extremity. The average neck angle is 130.
