Abstract: A multi-layered prosthetic element comprises a central body (1; 1?) of a substantially truncated conical shape and having a through axial cavity (2; 2?) open at both ends which gives the central body (1; 1?) a ring-shaped cross-section. The central body (1, 1?) comprises an outer portion (110; 110?), made of trabecular metal material, an inner portion (130; 130?), made of trabecular metal material, and an intermediate portion (120; 120?) made of metal material without significant porosity. The outer portion (110; 110?) and the inner portion (130; 130?) are integrally connected to the intermediate portion (120; 120?). The intermediate portion (120; 120?) is configured to mechanically resist to stresses transmitted to the inner portion (130; 130?) on one side and to the outer portion (110; 110?) on the other side.

Abstract: A set of instruments is for implantation of an acetabular prosthesis. The set of instruments may include a tool configured to operate in an acetabular cavity of a patient, a first emitter associated with the tool and configured to emit a control signal to be aligned with a reference signal for identifying a correct orientation of the tool relative to the acetabular cavity, and an acetabular reference guide to be fixed to a bone site of the patient separate from the acetabular cavity. The set of instruments may include a second emitter associated with the acetabular reference guide and configured to emit the reference signal.

Abstract: A method is for implantation of an acetabular prosthesis. The method may include positioning an acetabular calibration guide at an acetabular cavity of a patient, and positioning an acetabular reference guide at a bone site of the patient separate from the acetabular cavity.

Abstract: The device, tool, instrument and the like, for patellar resurfacing, according to the invention, comprises at least one bearing framework (IN), which incorporates a cutting slot (Tpg) and a lower support guide (G2) which may assume different positions with respect to the center of the patellar articular surface. The device is completed by an upper support guide (G1) of the patella for maintaining the shape-constraint coupling between the bearing framework and the patella. Advantageously the device uses the peripheral surface (and not the central one) of said patella, guaranteeing minimal invasiveness and perfect visibility.

Abstract: A prosthesis (10) for the reconstruction of the shoulder joint comprises a glenoid prosthesis (11) comprising an attachment support for the glenoid (13) and a joint element of the glenoid (14) and a humeral prosthesis (12) comprising an attachment support for the humerus (17) and a joint element of the humerus (15). The joint elements of the glenoid (14) and the humerus (15) are shaped in such a way as to achieve a spherical-type coupling therebetween for the artificial reconstruction of the shoulder joint. The joint elements of the glenoid (14) and the humerus (15) are constrained in a removable way by said attachment supports for the glenoid (13) and the humerus (17). The joint element of the humerus (15) is made of plastic material, in particular of polyethylene, and the joint element of the glenoid (14) is made of metallic material, in particular of a cobalt-chromium alloy.
