Embodiment Construction

[0050] Referring to the above figures, a joint prosthesis pin according to the present invention is shown generally at 1 and a tibial component for a knee prosthesis according to the present invention is shown generally at 30 .

[0051] exist Figure 7 In the non-limiting example shown, the pin 1 is associated with a knee prosthesis 2 delimited by a meniscus plate 3 and designed to be associated with the femoral condyle. However, the pin 1 may belong to the tibial component 30 (sometimes defined by the term tibial plate) or to another type of prosthesis designed for any joint compartment.

[0052] The pin 1 extends along its own linear longitudinal axis "X" and comprises a connecting portion 4 designed in relation to the prosthesis 2 and an engaging portion 5 adapted to be introduced into a hole formed in the bone.

[0053]In the preferred illustrated embodiment, the connecting part 4 and the engaging part 5 of the pin 1 are shown in circular cross-section, and the connecting...

Abstract

A pin for the anchoring of articular prostheses includes a connecting portion (4) with a prosthesis (2) and an engagement portion (5) in a hole obtained within a bone. The engagement portion (5) is at least partly deformable in a radial direction and in a resilient way, in order to allow the instantaneous blocking of the pin (1) in the hole and the primary fixing of the prosthesis (2) on the bone, so as to al low an easy primary fixing of the prosthesis by simply introducing with a pressure the connecting portion in the hole obtained within the bone itself.

Description

[0001] The parent case of this divisional application is the invention application with application number 200680032422.0 and application date of September 4, 2006. technical field [0002] The present invention relates to joint prosthesis fixation pins and joint prosthesis with such pins. [0003] The invention also relates to tibial components and knee prostheses comprising such tibial components. [0004] The invention belongs to the field of orthopedics and relates to a fixation system for microprostheses of different joint compartments, for example made of titanium, chrome-cobalt alloys or other metal alloys or ceramic materials. Background technique [0005] The present invention has found advantageous application in knee prostheses, particularly single compartment microprostheses (fixed to the femoral condyle, fixed to the tibial plate, fixed to the patella) designed for the knee joint. [0006] Like any other joint compartment, the knee joint is covered by a hyaline...
