Abstract: A surgical instrument includes a body having an actuator and being connectable with a pressurized fluid source. A first member is connected with the body and the fluid source. The first member is configured for connection with an implant disposable between a contracted configuration and an expanded configuration. A second member defines a cavity configured for disposal of the first member and the expandable implant. The second member is connected with the actuator for selective translation relative to the first member to position the implant in the contracted configuration. Systems, implants and methods are disclosed.

Abstract: 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.

Abstract: A spinal implant comprises a first member. A fastener is connected with the first member. A second member includes a deformable element engageable with the fastener such that the second member is translatable relative to the fastener in a first axial direction and translation of the second member relative to the fastener in a second axial direction is resisted and/or prevented. Systems and methods are disclosed.

Abstract: A spinal implant includes a locking mechanism. The locking mechanism includes an inner surface defining a tapered passageway. A tapered collet is configured for disposal in the tapered passageway. The tapered collet has an inner surface defining a passageway configured for disposal of a longitudinal member. The tapered collet is configured to translate within the tapered passageway between a non-locking orientation in which the longitudinal member is moveable relative to the tapered collet and a locking orientation in which the longitudinal member is fixed relative to the tapered collet.

Abstract: A spinal implant comprises an implant body including a first vertebral engaging surface and a second vertebral engaging surface. The vertebral engaging surfaces define a profile. The implant body further including an ipsilateral surface and a contralateral surface. A wall is disposed with the contralateral surface and is movable between a first orientation such that the wall is aligned with the profile and a second orientation such that the wall projects from the profile. Systems and methods are disclosed.

Abstract: An interspinous implant comprises a first member and a second member. The members define a pathway. A third member is movable along the pathway relative to the first member and the second member. Systems and methods are disclosed.

Abstract: A surgical injection device comprises a longitudinal element. A first member is disposed with the longitudinal element and includes a mating surface. A second member is disposed with the longitudinal element and includes a mating surface engageable with the mating surface of the first member. A valve is disposed with the members and axially translatable relative to the members between a vent position and a seal position. Systems and methods are disclosed.

Abstract: A spinal fixation system includes a first plate, a post fixedly attached to the first plate and extending transverse therefrom. A second plate receives the distal end of the post. A locking mechanism is configured to restrict at least one of axial translation and/or orbital rotation of the second plate with respect to the post. The locking mechanism can include a locking nut having two non-concentric cylinders which enable an interference fit between the nut and the post, thus restricting axial translation of the second plate.

Abstract: Devices and methods for replacing one or more spinous processes of a patient include a replacement body with a lamina portion positionable anteriorly toward the spinal canal along with a spinous process portion extending posteriorly from the lamina portion to replace a removed spinous process. Connecting elements extend from opposite sides of the body for connection to the vertebral body with anchors.

Abstract: A bone implant includes a first surface and a second surface. The first and second surfaces include a bioresorbable material. A third surface includes a biocompatible material disposed between the first and second surfaces. The third surface extends between a first end and a second end. The first and second ends each include an inner surface defining a cavity configured for disposal of a spinous process. The bioresorbable material of the first and second surfaces is a faster resorbing material than the biocompatible material of the third surface. The third surface provides structural integrity of the implant to maintain distraction between spinous processes so that the first and second surfaces fuse with at least a portion of the spine.

Abstract: A spinal rod having first and second end members. The end members may be flexible or rigid. An expandable intermediate section is positioned between the first and second end members. The intermediate section may be axially expandable upon the introduction of a substance into a port that may be located in either of the first and second end members or the intermediate section. The intermediate section may be expandable between a first size, where the first and second end members are spaced a first distance apart, and a second enlarged size, where the first and second end members are spaced a second greater distance apart.
