摘要:
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.
摘要:
The present invention relates to a multilayer structure (1) including a first upper layer (2) consisting of an organic matrix including collagen and at least a lower layer (3, 4, . . . 10) consisting of a composite matrix including hydroxylapatite and collagen. Furthermore, the present invention relates to a cartilaginous substitute including said multilayer structure (1) as well as an osteochondral substitute including said multilayer structure (1). Finally, the present invention relates to the use of said multilayer structure (1) for the preparation of said cartilaginous substitute and said osteochondral substitute for the treatment of cartilaginous defects and osteochondral defects or for the neo-formation of a cartilaginous tissue and/or a subchondral bone tissue.

摘要:
The present invention relates to a hydroxyapatite multi-substituted with, physiologically compatible ion species and to its biohybrid composite with a natural and/or synthetic polymer, which are useful in the preparation of a biomimetic bone substitute for treating bone tissue defects. Furthermore, the present invention relates to a method for their preparation and uses.
