An implantable medical device, such as an intervertebral spacer, may comprise a polymeric component and a metallic component. The metallic component can contain both porous metal and substantially-solid metal. The polymeric material can contain particles of an osseointegrative material. The metallic component can be more protruding toward bone than the polymeric component while having a smaller dimension of roughness than the polymeric component. In embodiments, the pin may press-fit against substantially solid metal. The porous metal may surround solid metal which in turn may surround the pin. The pin may have a press-fit with metal and a looser fit with polymeric component, if the metal components and polymeric components are trapped. A pin may connect superior and inferior metal components by a press-fit. The central opening may be exposed to porous metal and also to substantially-solid metal and to polymer. Specific geometries of implants are disclosed.

An intervertebral implant for implantation in an intervertebral space between vertebrae. The implant includes a body, an articulating element, and a blocking member. The articulating element can articulate in-situ, thereby allowing articulation of the spinal implant into a desired position within the disc space.

A spinal implant includes an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body defines a cavity. A plate is connectable with the implant body via a coupling member adjacent the cavity and is translatable relative thereto. The coupling member has a portion including a frangible torque limit. The plate defines at least one opening oriented to implant a fastener with tissue. Systems, spinal constructs, surgical instruments and methods are disclosed.

An expandable vertebral body device, system, instrument, and methods of assembly and using the device, system, and instrument are disclosed. The vertebral body device includes a body with a first end and a second end, a first rotating member rotatably coupled to the first end, a second rotating member rotatably coupled to the second end, a first extension member moveably coupled to the first end, and a second extension member moveably coupled to the second end. The expandable cage system comprises a vertebral body device and an insertion instrument. Methods for assembling and using the vertebral body device and instrument are also disclosed.

A corpectomy cage includes a main body, a first end cap, and a second end cap. The main body is shaped as a hollow rectangular prism, and includes a first end and a second end. The first end has a plurality of first receivers formed therein, and the second end has a plurality of second receivers formed therein. The first end cap includes a plurality of first legs configured to be received within respective first receivers to removably engage the first end cap with the first end of the main body. Similarly, the second end cap includes a plurality of second legs configured to be received within respective second receivers to removably engage the second end cap with the second end of the main body. Each of the end caps further includes a plurality of teeth arranged opposite the plurality of legs.

A tool for delivery and/or compaction of bone graft material includes a cannula with an inner lumen extending along a longitudinal axis from a hopper end of the cannula to a delivery tip of the cannula. A hopper with an internal volume for storing bone graft material is connected to the hopper end of the cannula with the internal volume of the hopper in communication with the inner lumen of the cannula for delivery of bone graft material from the hopper to the delivery tip of the cannula. An output shaft within the inner lumen extends along the longitudinal axis. The output shaft includes a helical screw thread extending radially outward from the output shaft toward an inner surface of the cannula. An actuator is connected to the hopper and to the output shaft to drive the output shaft rotationally relative to the hopper and to the cannula.

An intervertebral implant is disclosed. The implant can be made of Titanium or alloys thereof. A kit of intervertebral implants can be included having different lordotic profiles or having no lordotic profile. The intervertebral implants of the kit have endplates with thicknesses suitable to prevent the titanium endplates from being too stiff. The intervertebral implants can have apertures that extend through the endplates, but sufficient surface area at the outer surfaces of the endplates to avoid subsidence into the respective vertebral body.

An interbody implant includes an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. At least one of the vertebral engaging surfaces defines a cavity configured for disposal of bone growth detectable via medical imaging. Systems, spinal constructs, surgical instruments and methods are disclosed.

Misaligned bones on opposite sides of a joint are aligned using a first rigid extension securable to one of the misaligned bones using a particular surgical approach, and a second rigid extension having a contacting surface positionable in contact with the other the two misaligned bones from the same surgical approach. The first and second rigid extensions are moved with respect to each other using a lever, whereby a pulling force is exerted on one of the bones, and a pushing force on the other, thereby aligning the first and second misaligned bones.

Embodiments of bony region interbody systems, apparatus, and methods are described generally herein including a spinal interbody for insertion between vertebra, the interbody formed of metals or alloys while providing high radiographic visibility. Other embodiments may be described and claimed.
