The olecranon is situated at the proximal end of the ulna, one of the two bones in the forearm. [1] When the hand faces forward the olecranon faces towards the back (posteriorly). It is bent forward at the summit so as to present a prominent lip which is received into the olecranon fossa of the humerus during extension of the forearm. [2] [3]
Shoulder arthritis is a clinical condition in which the joint that connects the ball of the arm bone (humeral head) to the shoulder blade socket (glenoid) has damaged or worn out cartilage. Normally the ends of the bone are covered with hyaline articular cartilage , a surface so smooth that the friction at the joint is less than that of an ice ...

Weight training exercises where the arms are elevated above shoulder height but in an internally rotated position such as the upright row have been suggested as a cause of subacromial impingement. [7] Another common cause of Impingement syndrome is restrictions in the range movement of the scapulo-thoracic surfaces.
The Frozen stage is where the shoulder loses its range of motion and becomes stiff. Lastly, the thawing stage is where pain becomes minimal, and range of motion is restored. Exercise increases blood flow to the muscles affected which enhances blood flow. Regular exercise is a crucial part of the healing stages of adhesive capsulitis.
Olecranon bursitis is a condition characterized by swelling, redness, and pain at the tip of the elbow. [ 1 ] [ 2 ] If the underlying cause is due to an infection , fever may be present. [ 2 ] The condition is relatively common and is one of the most frequent types of bursitis .
Animation of shoulder joint showing the supraspinatus muscle. The rotator cuff muscles of the shoulder produce a high tensile force, and help to pull the head of the humerus into the glenoid cavity. The glenoid cavity is shallow and contains the glenoid labrum which deepens it and aids stability. With 120 degrees of unassisted flexion, the ...
The elbow is the region between the upper arm and the forearm that surrounds the elbow joint. [1] The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus.
