Abstract: Implantable orthopedic pain management devices are disclosed, including a body with a top surface having a radius of curvature, and a bottom surface with another radius of curvature, configured to be surgically implanted in a joint and to prevent contact between one or more bones in the joint, the body not being coupled to the one or more bones, and a peripheral protrusion disposed substantially about a perimeter of the body and having a substantially outward facing vertical surface, the peripheral protrusion being configured to prevent expulsion of the body from the joint.

Abstract: Implantable orthopedic pain management devices are disclosed, including a body with a top surface having a plurality of regions, each region having a radius of curvature, and a bottom surface having another radius of curvature, the body being configured to be disposed in a joint to prevent contact between one or more bones comprising the joint, the body also not being coupled to the one or more bones, a peripheral protrusion disposed substantially about a perimeter of the body and configured to prevent expulsion of the body from the joint, and a notch disposed substantially about the perimeter of the body and formed with a region of the top surface, the notch having a substantially outward facing vertical surface that is configured to retain the device in position within the joint.

Abstract: Techniques for implantable orthopedic pain management devices are disclosed, including incising an opening in a synovial capsule substantially surrounding a joint, using a first tool to form an enlarged opening in the synovial capsule, determining whether to modify the joint, the joint being modified using a second tool if a bone structure coupled to one or more bones is found within the joint and the bone structure is configured to limit articulation of the one or more bones when an implantable device is inserted into the synovial capsule and the joint, and inserting the implantable device into the synovial capsule through the enlarged opening, the implantable device being inserted into the joint using a third tool.

Abstract: Techniques for implantable orthopedic pain management devices are disclosed, including a saddle configured to axially align a top contoured surface to a bone surface and to axially align a bottom contoured surface to another bone surface, and a peripheral protrusion disposed on a peripheral surface of the saddle, the peripheral protrusion being configured to maintain dynamic stability of the saddle between the bone surface and the another bone surface.

Abstract: Techniques for implantable orthopedic pain management devices are disclosed, including a body having a body configured to be disposed in a cavity between a first toroidal shape and a second toroidal shape, the body being substantially saddle-shaped and configured to have a first saddle surface aligned on a first axis and a second saddle surface aligned on a second axis, and a channel formed on the body comprising a portion of the first saddle surface and another portion of the second saddle surface.

Abstract: An endplate for an intervertebral prosthesis includes a generally planar base plate, a first elevated region, or dome, within the base plate periphery, and a second elevated region, or dome, within the boundary of the first elevated region. The antero-posterior and side-to-side (medial-lateral) dimensions of the first elevated region are made to be unequal in order to provide resistance to torsional stresses, and the laterally opposite sidewalls of the first elevated region are defined by arcs that terminate in sagittal planes of the endplate, and are symmetrical with respect to a coronal plane of the endplate. A bone rasp and a groove cutter for use in implanting the prosthesis are also provided.

Abstract: The present invention provides an orthopedic device assembly comprising a first assembly element, a second assembly element, and a retaining mechanism. The first assembly element has a recess that receives the second assembly element, and the retaining mechanism holds the second element in an assembled state with the first assembly element. The retaining mechanism includes a retaining member with an angular cross-section defined by a base portion and a lateral flange portion projecting from the base portion. The retaining member is inserted through an aperture of the first assembly element into a groove in a wall of the recess of the first assembly element, with the flange portion projecting laterally of the groove and overhanging a shoulder portion of the second assembly element so as to retain the second assembly element in the assembled state with the first assembly element.

Abstract: An endplate for an intervertebral disc prosthesis includes: a plate member having a generally planar rim for contacting the peripheral cortical rim of a vertebral body, and an elevated region within the rim having an anterior region and a posterior region, wherein the anterior region of the elevated region is preferably recessed with respect to the posterior region and is treated to promote bone ingrowth. The endplate may be provided with a medial fin extending partway from the anterior edge of the endplate toward the posterior edge of the endplate.
