摘要： The invention disclosed herein includes implant features that can be used, in some embodiments, on devices with a volumetric density of less than about 100 percent and devices with a surface roughness of some value. The implant features include one or more protrusions mounted on the forward edge of an implant that can ease the distraction of tissue during implantation and reduce the occurrence of damage during a manufacturing process. In some embodiments, the protrusions have gaps in a non-axial direction with respect to the implant to allow axial compression with respect to the protrusions. In some embodiments, the protrusions have a circumferential gap between them and a body of a device to reduce any impact on the device's elastic modulus.

摘要： A prosthetic total knee replacement system comprises a distal femoral implant component, a tibial tray implant component and a fixed bearing tibial tray insert. The fixed bearing tibial tray insert is fixed to the tibial tray and articulates with the distal femoral implant component. The fixed bearing tibial tray insert component has a medial-lateral centerline and a stabilizing post. The stabilizing post has a medial-lateral centerline offset laterally from the medial-lateral centerline of the fixed bearing tibial tray insert.

摘要： The invention relates to an articulating joint spacer for temporary replacement of a joint, whereby the joint spacer comprises two spacer parts which each comprise one sliding surface on which the spacer parts, in the patient-inserted state, touch against each other in mobile manner and roll off on each other, and the remaining spacer parts are made, at least in part, of a second bone cement that contains at least one water-soluble antibiotic. The invention also relates to a method for producing a two-part articulating joint spacer, in which a sliding surface is formed in both spacer parts from a low-abrasion first bone cement and at least the surfaces of the remaining spacer parts, at least 50% thereof, are formed with a second bone cement that contains at least one water-soluble antibiotic.

摘要： A composite article (e.g., prosthesis) and method of preparing the article is provided. An article may include a body having a matrix of a first hardness having a plurality of particles of a second hardness embedded in the matrix in fixed locations, the second hardness being harder than the first hardness, and the matrix having an external wear surface with a portion of the particles being proximal to or exposed at the external wear surface. The matrix with the particles may improve the life and durability of the article.

摘要： Described here are deformable, monolithic, stabilization implants suitable for use within bone and between bones to fuse vertebral bodies, to repair herniated discs, or to repair spinal compression fractures. The implants are introduced into a chosen site at a first, smaller height and then plastically deformed to achieve a second, but unique, pre-selected, larger height. Variations of the device provide one or more specific larger heights. The devices are suitable as intervertebral spinal fusion implants for the immobilization of adjacent vertebral bodies. Methods of and instruments for deployment of the implants are also described. Also described are variations of the device suitable as sizing instruments.

摘要： An implant with an interference fit fastener for attaching the implant to a bone. The interference fit prevents backout of the fastener after the attachment. The implant may include a passage with a first end and second end. The passage may include a first interference section between the first and second ends. A fastener with an elongated shape may be sized to extend through the passage to attach the implant to the bone. The fastener may include a second interference section. During insertion of the fastener through the passage and into the bone, the second interference section of the fastener may contact against and modify or be modified by the first interference section of the passage. This modification may create the interference fit between the implant and the fastener that prevents backout. The interference sections may remain in contact or may move apart once the fastener is fully attached to the bone.
