Modular bone reinforcement systems, bone plates, assembled bone reinforcements, and methods of reinforcing a bone are described. A modular bone reinforcement system includes a plurality of bone plates, each of which has a series of tabs disposed along at least one edge of the bone plate for forming a snap-fit attachment to a mating series of tabs of another bone plate of the plurality of bone plates to form an assembled bone reinforcement. A first bone plate of the plurality of bone plates has a first shape and a second bone plate of the plurality of bone plates has a second shape that is different from the first shape. The modular bone reinforcement system can include additional components, such one or more fixation devices, reduction devices, navigation aids, or other components.

A spinal implant formed from a hinged distractor having an upper and lower support body that is hinged by use of pinions. An insert body is constructed and arranged to slide between the section to expand the height and to maintain a space therebetween. The insert body may include a leading edge that is tapered to allow ease of insertion. A trailing edge of the insert body includes a pin to allow ease of insertion along a curvature path.

A radiocarpal wrist joint replacement includes a radial member configured to be affixed to a portion of an end of the radial bone proximal to the wrist including a fixture to be affixed over a longitudinal aspect of the radial bone and a radial resurfacing plate having a substantially concave surface configured to be located at the end of the radial bone. A carpal capitate bone insert configured to be inserted and affixed into the carpal capitate bone. A bulbous component includes a first convex head and a second convex head, substantially opposite each other and connected by a neck between the first and the second convex head. The radial resurfacing plate of the radial member with the concave surface is configured to be operably coupled to the second convex head of the bulbous component so as to allow radial freedom of motion in the joint replacement.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. The fusion device described herein is capable of being installed inside an intervertebral disc space at a minimum to no distraction height and for a fusion device capable of maintaining a normal distance between adjacent vertebral bodies when implanted.

The present disclosure relates to expandable interbodies that include superior and inferior shells and a control assembly positioned between and inside of the shells, the control assembly including nested cages operably connected to each other with an adjustment screw. Rotation of the adjustment screw translates the cages relative to each other, which in turn causes the shells to open or expand.

The three-dimensional lattice structures disclosed herein have applications including use in medical implants, Some examples of the lattice structure are structural in that they can be used to provide structural support or mechanical spacing In some examples, the lattice can be configured as a scaffold to support bone or tissue growth Some examples can use a repeating modified rhombic dodecahedron or radial dodeca-rhombus unit cell. The lattice structures are also capable of providing a lattice structure with anisotropic properties to better suit the lattice for its intended purpose.

A carpal capitate bone insert configured to be inserted and affixed into the carpal capitate bone. A bulbous component includes a first convex head and a second convex head, substantially opposite each other and connected by a neck between the first and the second convex head. The radial resurfacing plate of the radial member with the concave surface is configured to be operably coupled to the second convex head of the bulbous component so as to allow radial freedom of motion in the joint replacement.

A multi-function device useful in a surgical procedure for implanting a cartilage repairing implant in a bone is disclosed. The device includes a plurality of bone defect sizing rings or discs, where each bone defect sizing ring/disc includes a portion that is used to determine the size that correlates to the perimeter shape and size of the cartilage repairing implant. The inventive device also includes a feature that can be used to gauge the proudness of the cartilage repairing implant after the implant has been implanted into a bone.

A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.
