This disclosure provides vertebral implants, fastening devices for vertebral implants, and implant instrumentation, and various combinations thereof. In some embodiments, the implant comprises a peripheral wall extending according to a vertical axis between upper and lower surfaces of the implant, with each such surface configured to be placed in contact with a vertebral structure, respectively, at the top and the bottom of the vertebral segment replaced by the implant. Some embodiments comprise fastening means, deployment of which anchors the implant in the lower and upper vertebral structures. Some fastening means may be deployed by sliding parallel to the vertical axis of the implant, and may comprise a plate with at least one part remaining in contact with the peripheral wall of the implant when deployed and a pointed end projecting from one of the upper and lower surfaces of the implant to enter a vertebral structures on completion of deployment.

Disclosed are devices for the fixation and support of vertebrae, particularly adjustable spinal implant devices.

A patient-specific artificial temporomandibular joint is proposed. The patient-specific artificial temporomandibular joint includes: a temporal bone coupling part including a fixing body that is fixed to the temporal bone of a patient and a head receiver that is detachably coupled to the fixing body and provides a close-contact curved surface being open downward; and a mandible coupling part including a coupling body that is fixed to the mandible of a patient and a head that has a spherical shape and is supported by the coupling body in contact with the close-contact curved surface of the head receiver. The patient-specific artificial temporomandibular joint is manufactured by 3-D printing on the basis of shape data of the temporal bone or the mandible of a patient, so a good implanting effect is provided and the patient quickly recovers. Further, worn parts can be partially replaced, thus there is a little burden of maintenance.

Disclosed is a height-expandable spinal cage including an upper plate and a lower plate disposed to face each other, a frame disposed between the upper plate and the lower plate, the frame having a space formed therein, a block disposed between the upper plate and the lower plate and configured to be movable in a longitudinal direction inside the frame, and a driving bolt having one end thereof connected to the block to move the block. The height-expandable spinal cage is implanted into an affected area while occupying the minimum height thereof and to be expanded between vertebral bodies.

A modular augment cone system and methods of implanting the modular augment cone system. The system includes a main body cone a first cutout in the cone wall, and including a proximal end, a distal end, and a cone wall extending between the proximal and distal ends. A portion of the cone wall proximal to the first cutout includes an attachment feature. A first augment cone is positionable in the first cutout, the first augment cone including an attachment feature configured to mate with the attachment feature of the cone wall to attach the first augment cone into the first cutout. The main body cone can include a second cutout in the cone wall. In such systems, the modular augment cone system can include a second augment cone configured to mate with an attachment feature of the cone wall to attach the second augment cone into the second cutout.

According to some embodiments, a method of inserting a lateral implant within an intervertebral space defined between an upper vertebral member and a lower vertebral member includes creating a lateral passage through a subject in order to provide minimally invasive access to the intervertebral space, at least partially clearing out native tissue of the subject within and/or near the intervertebral space, positioning a base plate within the intervertebral space, wherein the base plate comprise an upper base plate and a lower base plate and advancing an implant between the upper base plate and the lower base plate so that the implant is urged into the intervertebral space and the upper vertebral member is distracted relative to the lower vertebral member.

The present disclosure provides a glenoid implant system for a reverse shoulder implant system that includes a glenoid implant having a center post, and also includes an angled baseplate comprising a bone facing surface to face an implant site prepared in a glenoid region of a patient, and an implant facing surface to face and engage the glenoid implant and receive the center post of the glenoid implant, wherein the implant facing surface being at an angle with respect to a centerline of the bone facing surface.

The present invention provides a cage holder for a spinal fusion cage which is mounted on the spinal fusion cage, thereby allowing the spinal fusion cage to be stably inserted between vertebral bodies. The cage holder may be engaged with the spinal fusion cage to insert the spinal fusion cage between the vertebral bodies at the lowest height, and may be reliably separated from the spinal fusion cage after the surgery. In addition, when mounting the cage holder on a height adjustable spinal fusion cage, the cage holder may visually indicate an amount of change in the height of the spinal fusion cage.

An expandable intervertebral implant having an upper body portion, a lower body portion opposite the upper body portion, a wedge member connecting the upper body portion to the lower body portion, a nose member having a tapered distal end and a proximal end opposite the distal end, and an actuator disposed between the nose member and the wedge member, for translation of the wedge member along a longitudinal axis of the implant. A pin connects to the actuator for positioning the nose member relative to the actuator. Translation of the wedge member along the longitudinal axis of the implant displaces the upper body portion and the lower body portion away from each other, thereby expanding the intervertebral implant.

A bone implant for enclosing bone material is provided. The bone implant comprises a nonwoven mesh having an inner surface and an outer surface opposing the inner surface and configured to receive a bone material when the inner surface of the mesh is in an open configuration. A plurality of projections are disposed on or in at least a portion of the inner surface of the mesh, the outer surface of the mesh or both the inner and outer surfaces of the mesh, the plurality of projections extending from at least the portion of the inner surface, the outer surface of the mesh or both the inner and outer surfaces of the mesh and are configured to engage a section of the inner surface of the mesh or a section of the outer surface of the mesh or both in a closed configuration so as to enclose the bone material.
