A vertebral fixation plate assembly for securing adjacent vertebral bodies is provided that is configured to distract or extend along its length, as well as provide multiple degrees of freedom between the fixation points and the vertebral fixation plate in order to accommodate different installation locations, as well as different surgical approaches. Methods of using the vertebral fixation plate assembly are also provided.

INTERBODY CAGE DEVICE AND METHODS OF USE

A spinal interbody fusion device for use in a plurality of surgical approaches includes a cage, a top end, a bottom end, and at least a first side representing the width of the cage and at least a second side representing a length of the cage. The cage includes fixation holes and inserter holes, with each fixation hole being configured for accepting a screw or anchor and each inserter hole being accessible for one or more surgical approaches for performing a spinal fusion. Also included are methods for selecting a size of an intervertebral implant and methods of surgically approaching a spine of a patient for spinal surgical procedures.

Expandable lordosis intervertebral implants

This present subject disclosure provides a novel implant which is readily adjustable to provide a precise angle of lordosis. The implant may be positioned while in low profile, collapsed geometry, and may be expanded when in place to provide a precise angle of lordosis.

Bone grafting and compaction

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.

Posterior total joint replacement

A prosthetic system for implantation between upper and lower vertebrae comprises an upper joint component. The upper joint component comprises an upper contact surface and an upper articulation surface. The system further includes a lower joint component. The lower joint component comprises a lower contact surface and a lower articulation surface configured to movably engage the upper articulation surface to form an articulating joint. The articulating joint is adapted for implantation within a disc space between the upper and lower vertebrae, allowing the upper and lower vertebrae to move relative to one another. The system further includes a bridge component extending posteriorly from one of either the upper or lower joint components and from the disc space. The bridge component has a distal end opposite the one of the either upper or lower joint components. The distal end of the bridge component comprises a connection component adapted to receive a fastener.

A system for implanting an inter-body device between adjacent vertebrae comprises an inter-body device having a plurality of cans secured to a flexible bridge and having a relief portion therebetween. An inserter tube and complementary bullnoses are advantageously secured to the vertebrae by an extension arm for securing the assembly precisely in place. A plurality of articulating trial implants are provided to test fit a disc space for the proper sized inter-body device.

Intervertebral disc prosthesis and method
09814594 · 2017-11-14 · ·

The present disclosure generally relates to an intervertebral disc prosthesis for partially or totally replacing an organic intervertebral disc. The disc prosthesis includes an interbody device, a face plate and a pair of locking mechanisms for achieving dual fixation in the cephalad and caudal direction. Methods according to the present disclosure achieve such dual fixation in a single fixation step.

BONE SCREW
20170266007 · 2017-09-21 · ·

Method for manufacturing a bone pin for connection to a bone, particularly for fixing an implant to a bone, the bone pin having an implant contacting part arranged to contact the implant in connected situation and a bone contacting part arranged to engage the bone in connected situation, wherein the method comprises the steps of:—providing bone information which is indicative for the bone which the bone contacting part is arranged to engage;—providing a bone contacting part which is customized on the basis of the bone information for engaging said bone;—providing an implant contacting part; and—assembling the bone contacting part and the implant contacting part for manufacturing the pin.

Adjustable implant and insertion tool
09808353 · 2017-11-07 · ·

An adjustable spinal implant includes a lower body, an upper body, a locking pawl, and a locking key. The upper body and the lower body are pivotable relative to one another between a collapsed position and an expanded position. The upper body includes a locking flange that extends towards the lower body. The locking pawl is coupled to the lower body and is moveable between a locked position such that the upper and lower bodies are fixed relative to the one another and an unlocked position such that the upper and lower bodies are moveable relative to one another. The locking key is moveable between a locked state such that the locking pawl is fixed in the locked position and an unlocked state wherein the locking pawl is moveable between the locked position and the unlocked position.

Orthopaedic Implants Having Self-Lubricated Articulating Surfaces Designed to Reduce Wear, Corrosion, and Ion Leaching

An orthopaedic implant can replace a joint in a patient. The orthopaedic implant includes a first component having a first component surface and a second component having a second component surface. The first component surface and the second component surface mate at an interface. The first component surface includes a metal substrate, a nanotextured surface, a ceramic coating, and a transition zone. The nanotextured surface is disposed directly upon the metal substrate and has surface features in a size of 10.sup.−9 meters. The ceramic coating conforms to the nanotextured surface and includes a plurality of bio-active sites configured to attract and retain calcium and phosphorous cations. The transition zone is disposed between the metal substrate and the ceramic coating. The transition zone includes a concentration gradient transitioning from the metal substrate to the ceramic coating and there is no distinct interface between the metal substrate and the ceramic coating.
