Modular humeral prosthesis

Modular humeral prosthesis suitable for implant in a humeral seating of a humerus, comprising an articulation component, a distal joint element able to be inserted into said humeral seating along an insertion axis, and an adapter body provided with a support positionable in the humeral seating and that has a coupling seating to connect said articulation component and provided with a connection unit inserted into said support to connect said distal joint element to said adapter body in a releasable manner, wherein said connection unit comprises:

• a clamping element associated in a selectively releasable manner to the distal joint element,
• an anchoring element configured to clamp the clamping element against axial extraction movement in an axial direction toward the outside of the humeral seating,
• an attachment element associated with the clamping element and the distal joint element to clamp the distal joint element in an axial direction toward the inside of the humeral seating,
• wherein said support has a through coupling seating configured to receive and position said clamping element inside it, and also configured to allow the insertion and extraction of said distal joint element through said support without removing said support from the humeral seating;
• and
• wherein internally the clamping element has a cylindrical configuration and externally a truncated cone configuration.
