    Abstract: An orthopaedic prosthetic system includes a plate having one or more flanges and an acetabular shell component. Each flange includes a surface configured to engage a patient's bone. The plate also includes a central ring that engages a lip extending from an outer surface of the shell component. The ring may be mechanically attached to the lip using multiple fasteners. The system may include multiple plates each having a different configuration from other plates, and may also include multiple shell components each having a different configuration from other shell components. Methods for assembling and using the prosthetic system are also disclosed.

    Abstract: A prosthesis comprising: an inner layer formed from a polyaryletherketone; a first outer layer adjacent to said inner layer formed from a porous polyaryletherketone, at least some of said pores having located therein material to promote osteointegration; and a second outer layer adjacent to said first outer layer formed from a porous polyaryletherketone, a portion of said pores being free of material to promote osteointegration. The invention also relates to a method of manufacture of the prosthesis. In an alternative arrangement, the prosthesis comprises: an inner layer formed from a polyaryletherketone; a first outer layer adjacent to said inner layer formed from a porous polyaryletherketone, at least some of said pores having located therein material to promote osteointegration having a crystallinity of from about 60% to about 90%; and a second outer layer adjacent to said first outer layer formed from a porous polyaryletherketone, at least a portion of said pores having located therein material to promote osteointegration having a crystallinity of less than about 50%.

    Abstract: The present invention provides a biocompatible coating comprising calcium phosphate that is functionally graded across the thickness of the coating. The coating, which preferably includes hydroxyapatite, is particularly useful for coating implants, such as dental or orthopedic implants. The functionally graded coating is generally crystalline near the interface with the surface of the implant, with crystallinity and crystal diameter decreasing toward the outer layer of the coating. The invention further provides methods for preparing a coated implant comprising a functionally graded calcium phosphate coating thereon.

    Abstract translation: 本发明提供一种生物相容性涂层，其包含在功能上分级穿过涂层厚度的磷酸钙。 优选包括羟基磷灰石的涂层对于涂覆植入物例如牙科或矫形植入物是特别有用的。 功能梯度涂层在与植入物表面的界面附近通常是结晶的，结晶度和晶体直径朝着涂层的外层减小。 本发明进一步提供了制备涂覆植入物的方法，其中包括其上功能性梯度的磷酸钙涂层。
