Abstract: A bone anchor includes a distal bone engaging portion, a proximal portion extending from the distal bone engaging portion that includes a thread profile, and a mating element that threadingly engages the thread profile of the proximal portion. A retention feature between the mating element and the proximal portion deformably engages at least one of the mating element and the proximal portion to resist the mating element from moving relative to the proximal portion of the bone anchor.

Abstract: Vertebral implants sized to be inserted into a patient and positioned in an interspinous space. The implants may include a body and a pair of wings that extend outward beyond a first side of the body. The implants are sized and configured for the body to be positioned in the interspinous space with the wings on opposing lateral sides of one of the spinous processes. The wings may be adjusted to various spaced-apart distances to be positioned on the opposing sides of the spinous process. The implants may further be selectively adjustable between a collapsed orientation and a deployed orientation. The collapsed orientation includes one or both wings aligned with the main body to reduce an overall size of the implant to facilitate insertion into a patient. The extended orientation includes the wings extending outward from the first side of the body and along the lateral sides of the spinous process.

Abstract: The present application is directed to connectors for attaching a vertebral rod to an anchor. The connectors may include a body with a first channel to receive the vertebral rod and a second channel to receive the anchor. A cradle may be positioned in the body to contact the vertebral rod. The cradle may be pivotally positioned in the body to accommodate a vertebral rod that is at various angular positions within a predetermined plane. A set screw may engage with the body to secure the vertebral rod to the body and the body to the anchor.

Abstract: Medical devices for the treatment of spinal conditions are described herein. The medical device includes a pair of superior plates with spikes adapted to be embedded in a superior spinous process and a pair of inferior plates with spikes adapted to be embedded in an adjacent inferior spinous process. The superior plates and inferior plates are connected to each other in such a way as to allow relative motion therebetween. A spacer may be disposed between the adjacent spinous processes.

Abstract: Medical devices for the treatment of spinal conditions are described herein. The medical device of this invention includes a spacer that is disposed between adjacent spinous processes and has a layer of a soft or compliant material. The layer is preferably thicker along those portions of the spacer directly contacting the adjacent spinous processes and is preferably thinner or non-existent adjacent to the anterior portion of the support member. This preferred asymmetry of the compliant layer allows the spacer to be seated between spinous processes as anteriorly as possible.

Abstract: An implantable article for use with an anchor and a non-metal rod assembly includes a ring having a body including an outer surface, an inner surface defining an aperture extending through the body configured to engage a non-metal rod. The ring body further includes protrusions extending from the inner surface into the aperture, wherein the protrusions are spaced apart from each other axially and circumferentially along the inner surface.
