ORTHOPEDIC IMPLANTS HAVING ORDERED MICROGEOMETRIC SURFACE PATTERNS

An orthopedic implant includes an implant element for surgical insertion into a bone of a patient, the implant element having a microgeometric repetitive surface pattern in the form of alternating ridges and grooves, each having a fixed or established width in a range of about 2.0 to about 25 micron...

Beschreibung
Zusammenfassung:	An orthopedic implant includes an implant element for surgical insertion into a bone of a patient, the implant element having a microgeometric repetitive surface pattern in the form of alternating ridges and grooves, each having a fixed or established width in a range of about 2.0 to about 25 microns (micrometers) and a fixed or established depth in a range of about 2 to about 25 microns, in which the microgeometric repetitive patterns define a guide for preferential promotion of the rate, orientation and direction of growth colonies of cells of the bone which are in contact with the surface pattern. Cette invention concerne un implant orthopédique comprenant un élément d'implant destiné à être inséré de manière chirurgicale dans un os d'un patient, ledit élément d'implant présentant un motif superficiel répétitif microgéométrique en forme de reliefs et de creux disposés en alternance, chacun présentant une largeur fixe ou établie comprise entre environ 2,0 et 25 microns (micromètres) ainsi qu'une profondeur fixe ou établie comprise entre environ 2 et 25 microns, lesdits motifs répétitifs microgéométriques définissant une voie de guidage favorisant de préférence la vitesse, l'orientation et le sens de la croissance des colonies de cellules osseuses qui sont en contact avec le motif superficiel.
