摘要： Methods for detecting positional movement of orthopedic implants are described herein. In one embodiment, the method may include receiving a two-dimensional image defining an image plane, the two-dimensional image capturing a reference marker received within the bone and an orthopedic implant received within a bone, calculating a first angle of the reference marker relative to the image plane based on previously stored dimensions of the reference marker, calculating a second angle of the orthopedic implant relative to the image plane based on previously stored dimensions of the orthopedic implant, comparing the first angle to the second angle to calculate a current angle of rotation, and comparing the current angle of rotation to a previously calculated angle of rotation to detect rotation of the orthopedic implant relative to the bone.

摘要： Multi-hooded enarthrodial joint implant has a ceramic articulating cup including a ceramic head-receiving cup having an articular surface upon which a head of a joint can articulate, and which, in general, has a margin generally about a hemisphere more or less and at least two hoods that are marginally extended continuations of superior one-half or so of cup containment of a sufficient magnitude to reduce an overall dimension of socket outlet to less than a hemisphere, which can embrace and contain the head. The head is made of ceramic and has a truncated generally circular cross section, a truncated surface with a feature for attachment of the stem, and an opposing articular surface for articulation against the articular surface of the ceramic head-receiving cup. As an ensemble, the cup is combined with the head, typically with a stem, for a total joint implant.

摘要： Various embodiments of implant systems and related apparatus, and methods of operating the same are described herein. In various embodiments, an implant for interfacing with a bone structure includes a web structure, including a space truss, configured to interface with human bone tissue. The space truss includes two or more planar truss units having a plurality of struts joined at nodes. Implants are optimized for the expected stress applied at the bone structure site.

摘要： The present invention provides artificial disc prostheses, methods and instrumentation for implantation and revision thereof. Each prosthesis may comprise superior and inferior end plates and a nucleus positioned between articular surfaces of the end plates. The end plates may have planar bone engagement surfaces with a plurality of self-cutting teeth. The articular surfaces of the end plates may be planar or include a flattened portion. The nucleus includes superior and inferior articular surfaces which may comprise flattened portions such that when the articular surfaces of the nucleus and the end plates are placed in cooperation in a preferred orientation, the flattened and/or planar portions are aligned. Each prosthesis may provide flexion/extension, anterior/posterior translation, lateral bending, and/or axial rotation degrees of freedom. One embodiment comprises a prosthesis with a first joint providing flexion/extension and anterior/posterior translation, and a second joint providing lateral bending and axial rotation.

摘要： Orthopedic implants having a bone interface member and a water swellable IPN or semi-IPN with a stiffness, hydration, and/or composition gradient from one side to the other and physically attached to the bone interface member. The invention also includes an orthopedic implant system including an implant that may conform to a bone surface and a joint capsule. The invention also includes orthopedic implants with water swellable IPN or semi-IPNs including a hydrophobic thermoset or thermoplastic polymer first network and an ionic polymer second network, joint capsules, labral components, and bone interface members. The invention also includes a method of inserting an orthopedic implant having a metal portion and a flexible polymer portion into a joint, including inserting the implant in a joint in a first shape and changing the implant from a first shape to a second shape to conform to a shape of a bone.

摘要： A method of forming an implant having a porous tissue ingrowth structure and a bearing support structure. The method includes depositing a first layer of a metal powder onto a substrate, scanning a laser beam over the powder so as to sinter the metal powder at predetermined locations, depositing at least one layer of the metal powder onto the first layer and repeating the scanning of the laser beam.
