A spine stabilization device having an interbody spacer shaped to be inserted between a vertebral body of an upper vertebra and a vertebral body of a lower vertebra. The device further includes a fixation device to be inserted after placement of the interbody spacer, the fixation device having a support portion securing the interbody spacer against escaping from between the vertebral bodies into a ventral direction. The support portion rests against a portion of an anterior surface of the interbody spacer, and includes an anchor. The anchor has an anchoring material portion that is inserted, in a liquid state, into cancellous bone tissue of at least one of the vertebral bodies of the upper and lower vertebra, to thereby infiltrate the cancellous bone tissue, and to harden thereafter so as to fix the support portion to the vertebral body.

Spine stabilization device, and method and kit for its implantation

An expandable implant device () for insertion between two vertebrae () is disclosed. The device () has a center body () one or more lift bodies () and an external retaining band (). The external retaining band () holds the sides () of the one or more lift bodies (). The center body () has ramp surfaces () having a plurality or sets of ramps () sloped for allowing upward movement of the one or more lift bodies (). The sides () have complimentary ramp surfaces that fit onto the ramps () of the center body (). The height of the device () is increased by upward movement or downward movement or both of the one or more lift bodies () driven by the lengthwise movement of the center body ().

Expandable spinal implant

An artificial disc device for replacing a damaged nucleus is disclosed. In one form, the device may be inserted in components such that the device may be assembled within and retained by the natural annulus therein. In another form, the device may be inserted into the natural annulus in a collapsed or compressed state or arrangement and then be expanded within and retained by the annulus therein. In a further form, the device may be provided with a releasable connection so that the device may be connected in an insertion configuration and may be released in an operable configuration. Insertion tools and methods are also disclosed.

Artificial disc device

A spine stabilization device is provided, the spine stabilization device including an interbody spacer shaped to be inserted between a vertebral body of an upper vertebra and a vertebral body of a lower vertebra, and including a top surface oriented towards the lower endplate of the vertebral body of the upper vertebra and a bottom surface oriented towards the upper endplate of the vertebral body of the lower vertebra; and a fixation device to be inserted after placement of the interbody spacer, the fixation device including a support portion securing the interbody spacer against escaping from between the vertebral bodies of the upper and lower vertebra into a ventral direction, the support portion shaped to rest against a portion of an anterior surface of the interbody spacer, and further including an anchor, the anchor including an anchoring material portion that is configured to be inserted, in a liquid state, into cancellous bone tissue of at least one of the vertebral body of the upper vertebra and of the vertebral body of the lower vertebra, to thereby infiltrate the cancellous bone tissue, and to harden thereafter so as to fix the support portion to the vertebral body.

Cephalad and caudal vertebral facet joint prostheses and methods of use are provided. The cephalad prostheses are adapted and configured to be attached to a lamina portion of a vertebra without blocking a pedicle portion of the cephalad vertebra.

Prostheses, tools, and methods for replacement of natural facet joints with artificial facet joint surfaces

A device is disclosed for securing a spinal rod to the spine which includes a head portion configured to receive a spinal rod, a locking cap configured to engage the head portion and the spinal rod upon rotation of the locking cap relative to the head portion to secure the position of the head portion relative to the spinal rod, and a fastener portion depending from the head portion and configured to engage the spine. The locking cap has discontinuous opposed engagement flanges that are received within opposed engagement slots of the head portion when the locking cap is rotated into a locked position.

Device for securing spinal rods

Disclosed are cement products, methods of forming cement using the cement product, and methods of using the cement product in orthopedic and dental applications. Generally, the disclosed cement product includes a first component comprising a polymerizable resin comprising ethylenic unsaturated double bond, a second component comprising a compound comprising more than one type of amine selected from the group consisting of primary amines, secondary amines, tertiary amines and quaternary amines, and, optionally, the cement product includes a bioactive component to promote bone formation.

An artificial disc device for replacing a damaged nucleus is disclosed. In one form, the device may be inserted in components such that the device may be assembled within and retained by the natural annulus therein. In another form, the device may be inserted into the natural annulus in a collapsed or compressed state or arrangement and then be expanded within and retained by the annulus therein.

A prosthetic spinal implant having a securing member for fixing the implant relative to an adjacent bone. In one form, the securing member is deployable into a portion of the vertebral space for affixing the implant between the vertebrae. The securing member may be disposed substantially within the body of a bearing member of the implant when the securing member is in an undeployed orientation. In other forms, the securing member is provided separately from the implant such that it may be inserted into the intervertebral space after the implant has been placed in an implanted orientation between the vertebrae. In such forms, the securing member is configured for ease of insertion between an outer bearing surface of the implant and an adjacent bone via linear or rotary motion.

Systems and methods for sizing, inserting and securing an implant in intervertebral space

Bone plate and bone screw lock systems are provided for use in surgical implants. In a preferred form, the bone plate or other implantable member defines a bore for receiving a bone screw and a recess in communication with the bore. A screw lock operates in the bore at the recess to engage and lock the bone screw against unintentional movement. The preferred screw lock is shifted about the screw between an unlocked position to allow manipulation of the screw and a locked position in which the screw lock grips the head of the screw to prevent movement of the screw. The screw lock preferably has a c-shaped collar configuration with opposing ends and a camming engagement with the plate or other member in the recess. Upon rotation of the screw lock, the camming engagement causes the ends of the collar to either shift toward one another in which the collar compresses about the screw to lock the screw or away from another to unlock the screw head.
