Publication number: 20090149960Abstract: Methods and instrumentation for implantation of an intervertebral disc prosthesis are provided. A guide tool with sagittal and coronal reference features guides placement of guide pins relative to a sagittal plane and a coronal plane of the vertebrae. A retainer lockable to the guide pins has a ratcheting mechanism providing distraction or compression. A rasp, planer or other tools may be aligned to the retainer and inserted into the intervertebral space to prepare the vertebral endplates. An interoperatively adjustable trial is alignable to the retainer and measures an angularity of the intervertebral space. A prosthesis with keying features may be mounted to a prosthesis inserter with complementary features, held by pivotable arms and compressed between prongs. The inserter may be aligned to the retainer and advanced to implant the prosthesis in the intervertebral space. A prosthesis remover may grip one prosthetic end plate and extract the entire prosthesis.Type: ApplicationFiled: November 25, 2008Publication date: June 11, 2009Applicant: SYNERGY DISC REPLACEMENTInventors: Dylan Hushka, Joshua A. Butters, Jeffery D. Arnett, Neil Duggal

Publication number: 20090076615Abstract: The present invention provides artificial disc prostheses, methods and instrumentation for implantation and revision thereof. Each prosthesis may comprise superior and inferior end plates and a nucleus positioned between articular surfaces of the end plates. The end plates may have planar bone engagement surfaces with a plurality of self-cutting teeth. The articular surfaces of the end plates may be planar or include a flattened portion. The nucleus includes superior and inferior articular surfaces which may comprise flattened portions such that when the articular surfaces of the nucleus and the end plates are placed in cooperation in a preferred orientation, the flattened and/or planar portions are aligned. Each prosthesis may provide flexion/extension, anterior/posterior translation, lateral bending, and/or axial rotation degrees of freedom.Type: ApplicationFiled: October 27, 2008Publication date: March 19, 2009Applicant: SYNERGY DISCInventors: Neil Duggal, Louise C. Raymond, Joshua A. Butters, Jeffery D. Arnett, Dylan M. Hushka

Publication number: 20090043392Abstract: An artificial disc prosthesis is provided. The prosthesis of the present invention enables spinal segment alignment by having a variable height across its surface. The variable height is achieved by an asymmetric artificial nucleus or by at least one variable height end plate.Type: ApplicationFiled: September 30, 2008Publication date: February 12, 2009Applicant: SYNERGY DISC REPLACEMENT, INC.Inventors: Neil Duggal, Louise Raymond, Daniel R.

Publication number: 20080215156Abstract: The present invention provides an implantable joint prosthesis configured to replace a natural joint, and methods for implantation. The prosthesis may include a first component implantable in a first bone, having a first bearing surface, and a second component implantable in a second bone, having a second bearing surface which corresponds to the first bearing surface. Each bearing surface may include a flattened section such that when the bearing surfaces are placed in cooperation with one another in a preferred orientation, the flattened sections are aligned. Alternatively, the bearing surfaces may have and asymmetric configuration, with non-congruent surfaces that may enable correction of deformity. Several types of implantable joint prostheses are disclosed, including: carpometacarpal, metacarpophalangeal, metatarsophalangeal, distal interphalangeal, proximal interphalangeal, ankle, knee, shoulder, and hip.Type: ApplicationFiled: March 4, 2008Publication date: September 4, 2008Applicant: SYNERGY DISC REPLACEMENTInventors: Neil A.
