  • Patent number: 10350071
    Abstract: A hemi-prosthesis implant comprises a replacement-joint part with an articulation surface for tribological pairing with a joint surface of a natural joint counterpart. The articulation surface is embodied with a coating applied on a substrate. The substrate provides a relief for the adhesion of the coating. The relief may comprise one or more of a plurality of grooves, a plurality of teeth, a ribbing, and a roughened surface. The relief may be embodied entirely or partially outside the articulation surface. The replacement joint part may optionally comprise a ventilation feature, and the articulation surface may be formed by injection molding on the substrate. The hemi-prosthesis implant may be part of an implant set that includes both a hemi-prosthesis implant and a total prosthesis implant, either of which can be chosen intraoperatively.

  • Patent number: 10131543
    Abstract: The method is for producing porous calcium deficient hydroxyapatite granules and comprises the following steps: (a) subjecting granules of calcium sulfate anhydrous (CSA), calcium sulfate dihydrate (CSD) or calcium sulfate hemihydrate (CSH), the granules comprising interconnected pores with a minimum mean diameter of 3 microns, to a first incubation in an alkaline aqueous solution having a pH-value of less than 10 and containing PO43? ions; (b) subjecting the granules to a second incubation in an alkaline aqueous solution having a pH-value of more than 10 and optionally PO43? ions; (c) filtering and drying the obtained porous granules of calcium deficient hydroxyapatite; and wherein (d) the sum of the amounts of PO43? ions present in the first and second incubation is at least as large as the amount of SO42? ions of the granules used for step (a).

  • Patent number: 9611173
    Abstract: A calcium phosphate cement composition that includes the following two components: A) one or several calcium phosphate powders suspended in an aqueous solution including inhibitor cations inhibiting a reaction of the calcium phosphate powders with water, the inhibitor cations being selected from Mg2+, Sr2+ and Ba2+ at a concentration greater than 0.01 M; and B) an aqueous solution including Ca2+ cations at a concentration greater than 0.1 M. This calcium phosphate cement compositions can be safely stored for years yet still retain its full reactivity when mixed.
