Abstract:
Prostheses and methods are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses have a pontoon shape with opposed elongated partially cylindrical sections connected by a bridge section. The bridge section can have various shapes, such as an offset, arched structure, to accommodate the delivery and/or positioning of a primary or supplemental support member or device between the first and second elongated sections, such as a sacral-alar iliac (S2AI) screw or surgical dowel member.
Abstract:
Prostheses are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses include a fixation composition that is adapted to transition from a flowable state, wherein the fixation composition flows into spaces between the prostheses and the dysfunctional SI joint structures when the prostheses are implanted in a dysfunctional SI joint, to a solid elastomer state upon application of radiation energy, wherein the fixation composition forms a positive fit connection by and between the prostheses and the dysfunctional SI joint structures.
Abstract:
A system for implanting an interbody device between adjacent vertebrae comprises an interbody device having a plurality of lobes extending outwardly from a longitudinal rib, and having a relaxed shape approximating the shape of the disc being replaced. An insertion guide is provided having a bore therein from a proximal end to a distal end thereof to accept said interbody device in an unrelaxed shape, wherein said distal end is shaped for insertion into an intervertebral space. The insertion rod may be positioned within said bore of said insertion guide whereby said interbody device is positioned within said intervertebral space by advancing said insertion rod into said insertion guide.
Abstract:
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.
Abstract:
An implant system having an inserter or implant-drill guide defining a plurality of overlapping bores or elongated passageways. The inserter or implant-drill bit guide provides a drill jig for defining a complementary-shaped drilled-out area in the first and second vertebra. The implant comprises a plurality or lobes or lobate shapes that are adapted in size to be snugly fit into the implant receiving area.
Abstract:
A stabilizer for receiving an end of a spinal implant. The stabilizer includes a gap that creates a socket for receiving the spinal implant. Bodies of the stabilizer are manufactured in a plurality of shapes. A cover is capable of blocking egress of the spinal implant from the socket.
Abstract:
Methods and devices are provided for repairing or replacing damaged, injured, diseased, or otherwise unhealthy posterior elements, such as the facet joints, the lamina, the posterior ligaments, and/or other features of a patient's spinal column. In one exemplary embodiment, an implant is provided having an anterior portion that is adapted to be positioned between adjacent vertebrae and a posterior portion that is adapted to be positioned around a spinal cord and to couple to a posterior surface of at least one adjacent vertebra. In use, the implant can allow the adjacent vertebrae to move relative to one another, thereby restoring normal function to the vertebrae.
Abstract:
A disc prosthesis comprises a first prosthetic device comprising a first upper housing and a first lower housing between which at least one first disc element is movably interposed. The disc prosthesis further comprises a second prosthetic device comprising a second upper housing and a second lower housing between which at least one second disc element is movably interposed. The first and second prosthetic devices are adapted for parallel placement within an intervertebral space.

Abstract:
A modular, prosthetic, implant assembly for replacing a shoulder or hip joint is implanted through a transosseous core approach. Typically, the main route for the transosseous core approach traverses through a more-accessible bone of the joint which can be aligned with a less-accessible bone of the joint in order to facilitate treatment of articular surfaces and/or other structures in the joint. A modular implant assembly is provided which can be passed through a relatively small bone hole and then assembled in situ partly in the bone hole and finished in the joint or wholly in the joint.
