Forearm rotation pain

Introduction Pain of the humeral neck fracture: There is obvious pain, tenderness and rotational pain in the forearm at the small head of the humerus.

Cause

The carrying angle and the elbow joint are mostly natural eversion. When the hand is lowered, the violence is transmitted from the distal and the proximal humerus to the elbow. When reaching the upper end of the humerus, the humeral head collides with the humeral head, causing the humeral head and the humerus. A fracture of the neck or both. If the violence continues, there may be fractures and dislocations of the olecranon or the external humerus.
