Expandable interbody and intravertebral body devices
A device for insertion into a spinal (intervertebral or intravertebral) space is expandable and contractable. The device includes a body assembly, a top member configured to fit within a gap in the body assembly, a drive gear disposed within the body assembly at a distal end of the body assembly, a proximal gear assembly, and a distal gear assembly. The drive gear includes a receiver accessible from outside the body assembly and configured to be rotated in order to rotate the drive gear. Each gear assembly is attached to the top member. The distal gear assembly engages the drive gear. Rotation of the drive gear in a first direction causes the gear assemblies to translate the top member away from the body assembly, and rotation of the drive gear in a second direction causes the gear assemblies to translate the top member towards the body assembly.
Corpectomy spacer and plate
An intervertebral body spacer includes an inferior plate portion; a superior plate portion vertically spaced above the inferior plate portion; and a central spacer portion between the inferior plate portion. The central spacer portion has a posterior vertical wall extending between the inferior plate portion and the superior plate portion, the posterior vertical wall including multiple windows therethrough, an anterior vertical wall opposite and spaced apart from the posterior vertical wall, the anterior vertical wall being solid, and a pair of side vertical walls spaced apart from one another and extending between the posterior vertical wall and the anterior vertical wall, the side vertical walls including multiple windows.
FEMORAL AUGMENTS FOR USE WITH KNEE JOINT PROSTHESIS
A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis. The present invention is intended for situations in which the distal portion of the femur is defective, and it provides a method and devices that allow for preservation of healthy peripheral bone, while still providing the necessary augmentation to the distal portion of the femur.
INTERBODY DEVICE INCORPORATING LATTICE STRUCTURE AND RELATED SYSTEMS AND METHODS
The present disclosure includes an orthopedic device, such as an implant, that comprises one or more latticed regions to aid in fusion or osteo-integration between the implant and a specific patient. The implant may have periodic, organic, hybrid lattice structures or a combination thereof to further facilitate biocompatibility and improve mechanical characteristics of the implant. Methods for fabricating a customized device are also described herein.
Expandable implant assembly
An expandable implant includes a base member including a top surface, a first end, and a second end, and defining a central cavity positioned between the first end and the second end; an adjustable member including a top surface and at least one control channel, wherein the adjustable member is adjustably coupled to the base member and movable between a first, collapsed position, and a second, expanded position; a control shaft rotatable received by the base member, wherein rotation of the control shaft cause relative movement of the adjustable member relative to the base member; and at least one control member received on the control shaft and by the control channel, wherein rotation of the control shaft causes the control member to translate along the control shaft and along the control channel.
Connective tissue repair technology
An implantable prosthetic device for the repair of damaged cartilage including methods of implantation and repair. The prosthetic device is formed from a biocompatible pad having an open structure connected to a textile or non-woven sheet-like anchor. In one embodiment the anchor comprises legs that extend away from a perimeter region of the pad and spaced apart along their respective lengths such that an in unfolded orientation, the longitudinal edges of neighbouring legs are not in contact with one another and a spatial gap is provided between the anchoring legs. The anchor may also be provided in the form of strips to which anchorage sutures or other medical cords may be attached to fixate the device between connective tissue.
Adjustable, Implantable Spinal Disc Device for Deformity Correction in Intervertebral Fusion Procedures
Representative embodiments are disclosed for a spinal disc device which is implantable between adjacent vertebral bodies. A representative spinal disc device comprises: a first transverse plate member; a first arcuate extension extending longitudinally from the first transverse plate member and having a first configuration; a second transverse plate member; and a second arcuate extension extending longitudinally from the second transverse plate member and having a second, mating configuration with the first configuration of the first arcuate extension and slideably moveable with respect to the first arcuate extension, with the first and second arcuate extensions further arranged to form a central through-channel between the first and second transverse plate members to hold bone graft material. In various embodiments, the first and second configurations of the first and second arcuate extensions are each a partially spherical, convex shell configuration providing for movement in both the sagittal and coronal planes for deformity correction.
Hip implant with porous body
A hip implant has a neck body that connects to a bone fixation body. The bone fixation body has a porous structure with an elongated shape. An internal cavity is formed in the bone fixation body and includes a substance to stimulate bone growth.
Stem for use in joint arthroplasty
The invention relates to a prosthesis for implantation into a long bone during joint arthroplasty, particularly Total Shoulder Arthoplasty and Total Hip Arthroplasty, and a method for use of the implant.
Low profile plate
The present application generally relates to orthopedic systems, and in particular, to systems including independent plates and spacers. A plating system can include a spacer and a plate that is independent from the spacer. A number of locking mechanisms can be provided to secure the plate to the spacer. In some cases, the spacer includes a pair of notches that extend on an outer surface of the spacer. The plate can include a pair of lateral extensions that can engage the notches to secure the plate to the spacer. In other cases, the spacer includes an opening including a pair of inlets. The plate can include an enclosed posterior extension that can be received in the pair of inlets to secure the plate to the spacer.
