Humeral Head Fracture

The shoulder joint is formed by the head of the humerus and the scapula. It is a complex system from a functional point of view, comprising 5 distinct joints. The cartilage that covers the joint surfaces protects the bones from direct friction and facilitates smooth movement during daily activities. The onset of certain pathologies, mainly degenerative but also traumatic, can lead to damage to the cartilage and a reduction in its thickness; the bone surfaces then come into direct contact, causing pain that can reach a disabling threshold.
