20120259365 | FACET FUSION IMPLANT, INSTRUMENTATION, AND SURGICAL PROCEDURE - A facet fusion implant, including a body having stepped surface means for contacting a stepped surface of a facet joint and preventing the facet fusion implant from coming out of the facet joint. An external sleeve compacting instrument for inserting bone enhancing materials in an implant. A method of using an external sleeve compacting instrument. A method of preparing a facet fusion implant with bone enhancing materials. A method of creating a facet joint fusion by inserting the implant in a facet joint, contacting the stepped surface with a stepped surface of the facet joint, preventing motion of the implant within the facet joint, and creating a facet joint fusion.

20120271420 | DISTRACTABLE SPINAL IMPLANT ASSEMBLY - A spinal implant assembly includes a housing for containing a bearing member therein and seating within an intervertebral space and a bearing member disposed within the housing for enabling disc-like movement between vertebrae defining the intervertebral space. A method of inserting the spinal implant assembly into the intervertebral space includes the steps of inserting the spinal implant assembly into the intervertebral space and then distracting the spinal implant assembly from a first condition in which the spinal implant assembly is floatable into the intervertebral space to a second condition in which the assembly is distracted to fixedly engage opposing vertebral services defining the intervertebral space. | 10-25-2012 |
20130268078 | LOAD SHARING INTERBODY FUSION DEVICE - The present invention is a load sharing intervertebral fusion device that allows for reconstruction of the proper disc space between two vertebral bodies while allowing bone material packed within the fusion device to share loading and stress for enhanced healing. The device includes two sections, an upper and lower section, separated by a bioresorbable spacer. The upper section slides relative to the lower section with the bioresorbable material being placed in load therebetween. The upper section and lower sections are effectively held apart, creating an initial fixed spacer for implantation of the intervertebral disc space. Openings in the implant construct allow for bone graft and bone substitutes to be placed within the implant to allow for fusion through the implant construct. After implantation and over a period of time based on bone resorbtion and remodeling, the spacer resorbs, thereby maintaining load on the bone graft material. | 10-10-2013 |
