A dynamic interspinous process device for implantation with respect to a first vertebra and an adjacent second vertebra is provided. The dynamic interspinous process device may include a first attachment side and a second attachment side. Each of the first attachment side and second attachment side may include a central portion, a first wing extending from the central portion, a second wing extending from the central portion, and one or more slots extending from an interior side of the respective attachment side to an exterior side of the respective attachment side. The one or more slots of the respective attachment side may be configured to allow the first wing and the second wing to move relative to one another in a direction of a longitudinal axis of the dynamic interspinous process device.

A device for placement between two adjacent spinous processes of a spinal column to treat a spinal condition, and a method for performing a procedure on a spine of a patient, are provided. The device may include a first member, a second member mounted onto the first member, and a locking plug configured to restrict movement of the second member relative to the first member. The method may include positioning a portion of a first member between two adjacent spinous processes of the spine, advancing a second member along a length of the first member, and restricting the second member from moving relative to the first member.

An expandable interspinous process fixation system capable of restoring spinal stability and facilitating fusion. In one embodiment, the expandable interspinous process fixation system includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. Each endplate supporting fixed and/or adjustable spinous process engaging plates.

The present invention generally relates to methods and device for treatment of spinal deformity, wherein at least one tether is utilized to maintain the distance between the spine and the an ilium to (1) prevent increase in abnormal spinal curvature, (2) slow progression of abnormal curvature, and/or (3) impose at least one corrective displacement and/or rotation.

Interspinous process spacing devices and associated methods are provided. In one embodiment, an interspinous process spacing device includes a first attachment side, a second attachment side, and a spacer. The first attachment side and the second attachment side each include a central portion, a first wing portion, and a second wing portion. The central portion includes an inner surface extending along at least a majority of an anterior-posterior height of the central portion, and the first wing portion includes an inner surface extending along at least a majority of an anterior-posterior height of the first wing portion. The inner surface of the first wing portion extends in a direction transverse to the inner surface of the central portion, and the anterior-posterior height of the first wing portion is less than the anterior-posterior height of the central portion.

The present invention relates generally to medical devices and methods generally aimed at spinal surgery. In particular, the disclosed system and associated methods relate to performing spinal fixation with the use of a deformity system.

A system for replacing at least a portion of a natural facet joint includes a fixation member implantable in a vertebra, an inferior facet articular surface and an inferior strut which may be formed separately from the inferior articular surface. The inferior strut has a first end securable to the fixation member and a second end which may comprise a sphere with a hemispherical surface. An attachment mechanism may include a capture feature shaped to receive the second end of the inferior strut, and the mechanism may provide an adjustable configuration, allowing polyaxial adjustment between the inferior articular surface and the second end. A locking member may be actuated to exert force on the second end to provide a locked configuration. The system may further include a superior facet joint implant with a superior articular surface shaped to articulate with the inferior articular surface.

An interspinous process device is configured for placement between adjacent spinous processes on a subject's spine. The device includes a housing configured for mounting to a first spinal process, the housing having a lead screw fixedly secured at one end thereof. A magnetic assembly is at least partially disposed within the housing and configured for mounting to a second spinal process. The magnetic assembly includes a hollow magnet configured for rotation within the magnetic assembly, the hollow magnet comprising a threaded insert configured to engage with the lead screw. An externally applied magnetic field rotates the hollow magnet in a first direction or a second, opposite direction. Rotation of the hollow magnet in the first direction causes telescopic movement of the magnetic assembly out of the housing (i.e., elongation) and rotation in the second direction causes telescopic movement of the magnetic assembly into the housing (i.e., shortening).
