A self-drilling bone fusion screw apparatus is disclosed which includes at least first and second sliding boxes. A first screw member having a tapered end and a threaded body is disposed within the first sliding box, and a second screw member having a tapered end and a threaded body disposed within the second sliding box. An adjuster adjusts the height of the sliding boxes. The screw members are screwed into vertebral bodies in order to fuse the vertebral bodies together. A plurality of the self-drilling bone fusion screw apparatuses may be attached together and/or integrated via a plate or cage. Also disclosed is a cervical facet staple that includes a curved staple base and at least two prongs attached to the bottom surface of the curved staple base.

A spinal construct includes a first endplate that is configured to engage a first vertebral surface. An expandable member is connected with the first endplate and includes a mating element. A second endplate is configured to engage a second vertebral surface and includes an in-situ guide surface engageable with the mating element to connect the member with the second endplate. Systems and methods are disclosed.

A prosthesis for implantation into a mammalian body, the device comprising: (a) a prosthesis for implantation into a mammalian body that includes a sensor array comprising a plurality of sensors mounted to the prosthesis; and (b) an electronics structure for receiving signals from the sensor array and wirelessly transmitting representative signals to a remote receiver, where the plurality of sensors are operative to sense pressure, applied to the prosthesis by another object, in at least two axes generally perpendicular to one another.

A placeholder for vertebrae or vertebral discs includes a tubular body, which along its jacket surface has a plurality of breakthroughs or openings for over-growth with adjacent tissue. The placeholder includes at least a second tubular body provided with a plurality of breakthroughs and openings at least partially inside the first tubular body. The first and second tubular bodies can have different cross-sectional shapes, can be are arranged inside one another by press fit or force fit or can be connected to each other via connecting pins and arranged side by side to one another in the first body.

A prosthetic intervertebral disc and methods for using the same are provided. The subject prosthetic discs are characterized by including top and bottom endplates separated by a fibrous compressible element that includes an annular region and a nuclear region. The two plates are held together at least one fiber wound around at least one region of the top endplate and at least one region of the bottom endplate. The subject discs may be employed with separate vertebral body fixation elements, or they may include integrated vertebral body fixation elements. Also provided are kits and systems that include the subject prosthetic discs.

The invention relates to an apparatus for inserting a cage between vertebrae, according to the inventive concept, includes a body accommodating an inner rod coupled to the cage, which is to be inserted between vertebrae, a push bar installed in the body to be slid and configured to push one side of the cage as the push bar is moved forwards from the body, a support bar supporting an opposite side of the cage and installed in the body to be slid to move rearwards when the push bar is moved forwards, and an adjustment unit installed in the body to be manipulated and configured to adjust movements of the push bar and the support bar such that a rotation amount of the cage is adjusted according to manipulation by a user.

A surgical robot system includes a robot. The robot includes a robot base and a robot arm coupled to the robot base. The robot also includes an end-effector coupled to the robot arm. The robot is configured to control movement of the end-effector to perform a surgical procedure. The robot also includes an inertial measurement unit coupled to the robot arm. The surgical robot system also includes camera that is configured to capture one or more pictures or videos used to determine a location of the end-effector. The inertial measurement unit is configured to capture one or more measurements used to determine the location of the end-effector when a view of the camera is occluded.

A system for treating a spinal disease by placement of an interbody spacer between vertebrae comprises a horizontally curved interbody spacer and a guiding tool. The interbody spacer includes a pair of contact surfaces for contact with the vertebrae, a convex ventral surface that connects the contact surfaces, and a concave dorsal surface that connects the contact surfaces. The interbody spacer includes an engagement portion, located along the direction in which the interbody spacer is curved, in the ventral surface and/or the dorsal surface. The guiding tool for guiding the interbody spacer to a predetermined position between the vertebrae includes, on a distal end, a guide rail portion to be fitted into one of the engagement portions. The radius of curvature of the guide rail portion in plan view is substantially the same as the radius of curvature of the ventral surface or the dorsal surface of the interbody spacer.

A curved expandable interbody device for placement between vertebrae having an upper structure, a lower structure, and a screw mechanism, wherein actuation of the screw mechanism moves the upper and lower structures between a collapsed configuration and an expanded configuration. A deployment tool couples to the curved expandable interbody device for positioning the device between adjacent vertebrae and actuating the screw mechanism, wherein the deployment tool can lock to the curved expandable interbody device and pivot relative to the curved expandable interbody device.

According to one example, a tibial prosthesis that optionally includes a baseplate and a tibial keel. The baseplate optionally including: a distal surface sized and shaped to substantially cover a proximal resected surface of a tibia; a proximal surface opposite the distal surface, the proximal surface having a lateral compartment and a medial compartment opposite the lateral compartment; a periphery extending between the distal surface and the proximal surface; a first pocket formed in the baseplate and recessed from the distal surface, wherein the first pocket is configured to receive a bone cement therein; a second pocket formed in the baseplate and recessed from the first pocket, wherein the second pocket is configured to receive a portion of the bone cement. The tibial keel extending distally from the distal surface to define a longitudinal tibial keel axis.
