Positioning the fusion implant between the cephalad vertebra and the caudal vertebra while the cephalad anchor blade and the caudal anchor blade are both held in the non-deployed position. Advancing the anchor blades to engage the vertebrae. Using a cephalad locking cam to lock the cephalad anchor blade in the deployed position and using a caudal locking cam to lock the caudal anchor blade in the deployed position.

SIX DEGREE SPINE STABILIZATION DEVICES AND METHODS
20220273457 · 2022-09-01 ·

An implant stabilizes two adjacent bones of a joint, while enabling a natural kinematic relative movement of the bones. Support components are connected to each bone of the joint, and a flexible core is interposed between them. The core and at least one of the support components are provided with a smooth sliding surface upon which the core and support component may slide relative to each other, enabling a corresponding movement of the bones. The surfaces may have a mating curvature, to mimic a natural movement of the joint. The core is resilient, and may bend or compress, enabling the bones to move towards each other, and or to bend relative to each other.

CONNECTING SLEEVE FOR ANCHORING SHAFTS OF TWO OPPOSITELY ARRANGED PROSTHESES

The invention relates to a connecting sleeve for anchoring shafts of two oppositely arranged prostheses, preferably on an elongate bone such as a femur or humerus. The reinforcing sleeve comprises two receiving bushes for one prosthesis shaft each and comprises a separable coupling region arranged therebetween for connection in such a manner as to resist shear forces and rotation. According to the invention, each receiving bush has, on the side thereof facing the coupling region, one fork of a pair of forks that interact with each other, and a fitting block is arranged on a base of the fork, the lateral surfaces of which fitting block have a distance that corresponds to an inner width of the fork, and the lateral surfaces are designed to contact flanks of the fork in a planar manner, at least one fastening screw being arranged transversely through the fork. The fork connection is simpler to produce than the known wedge connection and yet is sufficiently robust. Unlike in the case of the wedge connection, an exact fit is not required; a clearance fit between the fork and the fitting block is sufficient in principle, excessive play being eliminated by means of the fastening screw.

ARTICULAR SURFACE IMPLANT SYSTEMS AND METHODS INCLUDING GLENOID REVERSE SHOULDER

The present disclosure provides an implant system. The implant system includes an anchor configured to be secured to bone within an excision site formed in a patients glenoid, said anchor including a shank and an enlarged head. The implant system also includes a baseplate including a body comprising: a bone facing surface; an implant facing surface; and a channel configured to extend radially from an entrance in an outer periphery of said body to a central region of said baseplate, said channel configured to receive said enlarged head and a portion of said shank and including an open region formed, at least in part, in said bone facing surface. The implant system also includes an implant including a body defining a load bearing surface and a baseplate recess, said baseplate recess configured to receive at least a portion of said implant facing surface to said baseplate such that said implant is coupled to said baseplate.

MULTIAXIAL MODULAR TIBIA STEMS

Provided are tibia stem components of ankle replacement prosthesis that are designed to engage dense tibia bone to reduce implant migration over long term.

Fixation Devices And Prostheses For Soft Tissue Connection To The Same

An orthopedic assembly includes a tibial prosthesis that includes a body that defines an anterior side and a posterior side. The body further incudes a recess in the anterior side of the joint prosthesis and a plurality of openings that extend through the body from the anterior side to the posterior side thereof. At least a first and second opening of the openings are positioned at respective lateral and medial sides of a longitudinal axis of the tibial prosthesis. A modular insert is positioned within the recess of the body such that at least a portion of the modular insert is positioned between the openings of the body. The modular insert is formed separately from the tibial prosthesis and has a porous outer surface to promote tissue ingrowth.

HUMERAL AND GLENOID ARTICULAR SURFACE IMPLANT SYSTEMS AND METHODS

A shoulder implant system comprising a glenoid implant; a baseplate comprising an implant facing surface to face the glenoid implant; wherein the glenoid implant comprises at least one fixation element configured to engage with at least one fixation element of the baseplate; wherein the at least one fixation element of the glenoid implant comprises a center post having a distal end; wherein the at least one fixation element of the baseplate comprises a center post receptacle; wherein the baseplate comprises an outer periphery; wherein the implant facing surface of the baseplate comprises a channel which extends from the outer periphery of the baseplate to the center post receptacle of the baseplate; and wherein the channel is configured such that, during an assembly of the glenoid implant and the baseplate, the distal end of the post is movable in the channel from the outer periphery of the baseplate to the center post receptacle of the baseplate.
