METHOD AND IMPLANT DEVICE FOR GRAFTING ADJACENT VERTEBRAL BODIES
A methodology for grafting together adjacent bony structures is provided using an implant device having an endplate with an inner disc portion and outer ring portion spaced from the inner disc portion by a connecting wall disposed there between. An endplate interior surface includes a retaining structure for securing the endplate to one of the bony structures, and endplate an exterior surface has an integrally formed socket. A ball-joint rod has a longitudinally extending body and an end, and at least a portion of the ball-joint rod end is curvilinear in shape. The curvilinear ball-joint rod end is rotatably disposed in the endplate socket to fixedly interconnect the bony structures.
PROSTHETIC IMPLANTS INCLUDING A FRAME FOR FIXATION TO BONE AND RELATED METHODS
The present disclosure provides for prosthetic implants to be used in various surgical repairs, including for procedures like total shoulder arthroplasties and reverse total shoulder arthroplasties. The implants include two main parts—a frame and a prosthetic component. The frame includes an aperture that is configured to receive the prosthetic component, allowing the prosthetic component to make direct contact with bone at the surgical site. Various configurations are provided that allow the prosthetic component to be coupled to or otherwise engage with the frame, and at least some of the configurations are such that the reverse procedures can be done without having to fully re-tool and/or modify the bone. A variety of procedures resulting from the improved implants are also provided.
System and method for joint arthroplasty
An orthopedic joint prosthesis may include a first component, a bearing component, and a third component. The first component has a base and a keel protruding from the base to extend into a first bone. The keel's longitudinal axis is offset from a geometric center of the base. The base has a first articular surface and the bearing component has a second articular surface shaped to articulate with the first articular surface. A feature unitary with the first component reversibly attaches to the bearing component. The bearing component has a third articular surface shaped to articulate with a fourth articular surface on the third component. A distraction feature of the bearing component is shaped to provide alignment and/or distraction between the first articular surface and the fourth articular surface during insertion of the bearing component into a joint space between the first and second bones.
Disc replacement device and method of use
A disc replacement device including a first body member with a convex articulation surface and a second body member with a concave articulation surface is disclosed. When operably positioned, the convex articulation surface engages the concave articulation surface to provide for movement therebetween. The disc replacement device also includes a first opening in the first body member and a second opening in the second body member, wherein the openings are angled and extends from the front aspects of the body members through the external surfaces. The disc replacement device further includes at least two bone fasteners for insertion into the first and second openings to secure the disc replacement device to a first and second vertebra. An interbody motion device and fusion implant, as well as a surgical method for implantation are also disclosed.
Knee prosthesis and knee prosthesis component
A knee prosthesis includes a tibial component, a bearing and a femoral component. The tibial component includes a platform and at least one rib extending upwardly and forwardly, a front edge of upper surface of the platform is provided with at least one front lug boss, and back edge of the upper surface of the platform is provide with at least one back lug boss. The lower surface of the bearing is provided with a groove matching with the at least one rib, a front slot matching with the front lug boss and a back slot; the femoral component is articulated with the bearing; at least one rib is provided with a medial wall and a lateral wall, one of the them is provided with a bent portion and formed with a first inclined surface which extends in a direction away from the other one.
HEIGHT RESTORING DEVICE, INSERTION APPARATUS HAVING A HEIGHT RESTORING DEVICE AND METHOD FOR RESTORING THE HEIGHT OF AND STABILISING THE SPINAL COLUMN
The invention relates to a height restoring device for restoring the height of and stabilizing the spinal column, in particular for stabilizing broken vertebral bodies or contused intervertebral discs, which device can be arranged in an insertion position in a compression-fractured vertebral body or between adjacent vertebral bodies and once there, can be transferred from the insertion position into an expansion position by means of an expansion apparatus.
BODILESS BONE FUSION DEVICE, APPARATUS AND METHOD
A bodiless bone fusion method, apparatus and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bodiless bone fusion device comprises one or more extendable plates, one or more extending blocks in communication with the extendable plates, one or more positioning elements for adjusting the extendable plates by manipulating the extending blocks, and one or more support panels for holding the positioning elements and guiding the extendable plates. The plates are able to be advantageously positioned in the confined space between the vertebrae to help brace the device until the bone has fused.
Glenoid anchor for a shoulder joint prosthesis
The present invention relates to an improved glenoid anchor for a shoulder joint prosthesis, in particular a convertible prosthesis, of the type intended to be fixed to the glenoid cavity of the shoulder blade and comprising: —a pin (2) with an internally hollow and essentially thimble-like conical sleeve (12), which has a tapered distal end (3) and an open proximal end (4); —an annular recess (15) formed inside the cavity (13) of the pin (2) in the vicinity of said open proximal end (4), for receiving by means of snap-engagement an edge (34) of a lug (30) of a prosthesis component (9); —at least one pair of oppositely arranged anti-rotation notches (16, 17) in the proximity of said annular groove (15) for receiving by means of snap fit oppositely arranged teeth (18, 19) of the same lug (30) intended to be snap-engaged together with said pin (2).
SHOULDER PROSTHESIS COMPONENTS AND ASSEMBLIES
Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.
MODULAR ARTIFICIAL KNEE SYSTEM
A modular knee joint prosthesis is configured to move between an extended position and a flexion position. The modular knee joint prosthesis includes a femoral component that is configured to be mounted to a femur. The femoral component has a first cutout or opening in a central region thereof for receiving a femoral insert. The modular knee joint prosthesis also includes a tibial component that is configured to (i) be mounted either directly or indirectly to a tibia, and (ii) engage the femoral component. The tibial component has a second cutout or opening in a central region thereof for receiving a tibial insert. A kit includes the modular knee joint prosthesis, at least two of the femoral inserts having different geometries, and at least two of the tibial inserts having different geometries.
