A modular humeral prosthesis for replacement of the humeral head of a humerus (20).

The invention relates to implant plates used to stabilise a fracture in the head of the humerus and/or a fracture in the proximal humerus.

This means that the humeral head has come out of the glenoid.

The subscapularis controls in the internal rotation of the head of the humerus.

The head of the humerus is, however, quite large in comparison to the fossa.

Four tendons called the rotator cuff stabilize the head of the humerus (upper arm).

A shoulder replacement prosthesis has a head (12) for replacing the humeral head and a connection shaft (14).

Fine sharp stitches in front on the head of the right humerus.

A fracture pin (10) used to treat fractures, especially fractures of the head of the humerus, of a bone comprising several segments.

In particular, the flange acts to bridge the so-called bare area of the humeral head.

This usually involves reattaching the tendon to the head of the humerus.

The head is of a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.

The head of the humerus being the ball, and the glenoid cavity of the scapula is the socket.

The subacromial spacer according to the invention is therefore particularly suitable for treating those patients whose humeral head is not substantially compromised.

In rare cases, this can result in the death of bone parts (humerus head necrosis).
