Abstract: An assembly for attachment to a first implant component has a size and shape of a second implant component to be implanted together with the first implant component. The assembly includes a first body defining a protrusion and a second body including a recess into which the protrusion is insertable. When the protrusion is seated within the recess, the first and second bodies are removably connected such that the first and second bodies are prevented from separating. A modular kit includes a plurality of the first bodies each having a different size or shape, and a plurality of the second bodies each having a different size or shape. A method of assembling the assembly includes removably connecting the protrusion of the first body into the recess of the second body, such that the first and second bodies are prevented from separating, and positioning the assembly on the first implant component.

Abstract: In order to deliver porous particulate material into a cavity via a thin tube without substantially crushing the porous particulate material, a two-step process and an apparatus for use therein are provided. The two-step process involves inserting a first rod into the thin tube to push the porous particulate material therein; removing the first rod from the tube; and (a) inserting a second rod into the thin tube, or (b) joining a second rod with the first rod, and inserting the joined first rod and second rod, to push the porous particulate material which remains in the thin tube. In (a), the first rod has a cross sectional area significantly smaller than that of the thin tube, and the second rod has a cross sectional area which is about equal to that of the thin tube. In (b), each of the first rod and the second rod has a cross sectional area about half of the thin tube.

Abstract: Disclosed are interbody fusion spacers, or cages, for insertion between adjacent vertebrae. The cages may have integrated and deployable anchors that allow the cage to have a first, insertion configuration characterized by a reduced size to facilitate insertion through a narrow access passage and into the intervertebral space. Once implanted, the anchors of the cages may be deployed to enable better fixation to bone. The cages may promote fusion to further enhance spine stability by immobilizing the adjacent vertebral bodies.

Abstract: The invention relates to a bone screw system, an implant system and a method of locking a bone screw system into a bore. The bone screw system comprises a bone screw and a washer. The screw comprises a screw head and a screw shaft. The washer comprises a washer bore. A diameter of the washer bore is larger than an outer diameter of the screw shaft. This allows a displacement of the screw shaft within the washer bore. The diameter of the washer bore is smaller than an outer diameter of the screw head. This prevents the screw head from moving through the washer bore. The screw and the washer comprise each an engagement portion for an engagement with each other. At least one of these engagement portions comprises an inclined surface. The inclined surface is configured to force the screw shaft sideward upon screwing in of the screw so that a longitudinal axis of the screw is tilted relative to the axis of the washer bore.

Abstract: Jigs for guiding femur and tibia resectioning in knee surgery contain bone-jig contact surfaces and a cutting guide as a single unitary piece. Contact surfaces are curvilinear surfaces formed into ends of projections from a jig base. Each jig has three pairs of contact surfaces selected to abut low-wear, lateral and medial, articular surface features, such that only one self-locking position against the bone (or cartilage) is possible and the integral cutting guide will define only one cut plane for the resectioning. An improved rotational transformation that converts scan views into desired proper axes is based on projections of rotated coordinates onto the plane of rotation to produce parameters that closely correspond to the joint surfaces in the desired jig coordinates.
