Coronoid process, olecranon, ulna styloid process, stylus process, elbow
The forearm is made up of two bones. The ulna is on the little finger side, the radius is on the thumb side. Both bones are connected to one another by solid fiber strands (membrana interosea antebrachii).

The cubit forms with the Humerus (= Humerus) the main part of Elbow joint. The ulna is relatively thick at the elbow joint and thins towards the wrist. Here it only forms a small part of the wrist. At the elbow, the ulna is shaped so that it can accommodate the curve of the humerus. These two bones form the main part of the elbow joint. The Coronoid process is a protrusion of bone on the elbow joint that prevents the Elbow joint prevented.
The Olecranon is the elbow bone. It can be seen and felt as the tip of the sharply bent elbow joint.
The Stylus process (processus styloideus ulnae) is on the little finger side wrist palpable and forms a small part of the wrist.

- Cubit (Ulna)
- Spoke (radius)
- Stylus process (Ulna styloid process)
The ulna and the humerus form the elbow joint. It is a hinge joint. At the wrist, the ulna and the stylus form a small part of the wrist.

Diseases of the ulna
The bursa of the elbow joint is located above the olecranon. This bursa can become infected (Bursitis = Olecranon bursitis). If this inflammation cannot be contained conservatively, the bursa must be surgically removed.
In the context of a broken spoke near the wrist (distal radius fracture), the stylus extension (processus styloideus ulnae) can also break / tear off. These avulsions often do not heal even after immobilization with plaster of paris.
A Osteoarthritis of the elbow joint is rare as the elbow joint does not bear any load. Elbow joint arthrosis (= cubital arthrosis) is found more frequently in patients with an underlying rheumatic disease or in patients with jobs that require high physical stress on the elbow joint (e.g. construction workers).
Tennis elbow is a common disease of the elbow joint.
This is a very painful inflammation of the tendons of the forearm extensor muscles at the elbow joint, more precisely on the humerus near the elbow.
As a rule, the cause of tennis elbow is a combination of overload and wear and tear.

The golfer's elbow represents the partner to the tennis elbow.
In contrast to the tennis elbow, the golfer's elbow is a painful inflammation of the tendon attachment (med. Enthesopathy) of the forearm flexor muscles.
