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 distractor includes a first plate and a second plate. The first plate includes an outer surface having a surface irregularity provided thereon and an inner surface having a protrusion provided thereon. The second plate includes an outer surface having a surface irregularity provided thereon and an inner surface having a recess provided thereon. The protrusion engages with the recess in a ball and socket configuration that permits relative movement of the first and second plates.

A nucleus implant includes a core (10) arranged inside a nucleus pulposus space (Es) obtained after nucleotomy of the intervertebral disk (Di) and at least one extension (11) penetrating inside at least one channel (Co) formed in the vertebral body of the corresponding vertebra (Va, Vb) to strengthen and ensure a connection between the nucleus implant (1) and the bone body of the vertebra (Va) and/or (Vb) through the diffusion or migration of the viscoelastic material making up the nucleus implant in the cancellous bone of the vertebra.

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.

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.

The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.

This disclosure presents a MITLIF procedure. The procedure uses a single incision on one side and pedicle screws are placed on that side and through the same incision a facet screw is placed on the opposite side using a series of jigs, and, for example, the hole cutter, drill, guide shaft and screw driver described herein.

A method for performing lumbar interbody fusion surgery may include forming an access corridor through a facet joint of a patient, removing disc material from a disc space of the patient via one or more instruments advanced through the access corridor, and advancing an interbody device through the access corridor and into the disc space.

A method of surgically treating a patient suffering from severe pain and disability of the low back and buttock by stabilizing the patient's spinal column to their pelvis with an implant system including surgical tools and an implant designed to prevent movement between the sacrum and the ilium while being able to attach to a spinal fusion rod which connect to pedicle screws implanted in the bones of the spine of the patient in order to offer lasting relief of the patient's symptoms. The system is designed to address complications in adult spinal deformity by optimizing spinopelvic fixation via-a-vis the unique biomechanics of the SI joint. The sacropelvic system is a surgical solution which provides an additively manufactured implant at the base of the spine employing an S2AI trajectory while utilizing assisting technologies including surgical navigation and intraoperative neurophysiological monitoring.

The present disclosure pertains to ionic polymer compositions, including semi- and fully interpenetrating polymer networks, methods of making such ionic polymer compositions, articles made from such ionic polymer compositions, and methods of making such articles and packaging for such articles.
