| 20080281425 | Orthopaedic Implants and Prostheses - Disclosed herein are modular spinal implants having components which are interlocked together to form a single implant. Specifically exemplified herein are implants that are sectioned along a longitudinal plane. Implants are disclosed which include channels for inter-fragmentary association with an elongate bone screw and which allow for angular variability of the screw relative to the channel. Also disclosed is an anti-backout mechanism that helps prevent fixators from backing out upon securement of the implant in the spine. Kits comprising different sizes and inclination angles of components are disclosed, which can assist the surgeon in preoperatively assembling an implant to best fit in the surgical site of the patient. | 11-13-2008 |
| 20090043392 | Artificial Spinal Disc - 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. | 02-12-2009 |
| 20090043393 | Artificial Spinal Disc - 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. | 02-12-2009 |
| 20090069894 | Artificial Spinal Disc - The present invention relates to methods and devices for the treatment of disc disease and spinal deformities with an artificial disc replacement. | 03-12-2009 |
| 20090210062 | Orthopaedic Implants and Prostheses - Disclosed herein are spinal implants particularly useful in interbody fusion surgery. One embodiment pertains to a plate configured to establish desired lordosis and/or disc height that may be implanted and secured to a superior and inferior vertebral body. The plate may be interlocked with a spacer component to form a single implant. Also disclosed is an anti-backout mechanism that helps prevent fixators from backing out upon securement of the plate in the spine. Kits comprising different sizes and inclination angles of components are disclosed, which can assist the surgeon in preoperatively assembling an implant to best fit in the surgical site of the patient. | 08-20-2009 |
| 20110082556 | Artificial Spinal Disc - An artificial disc prosthesis is provided. The prosthesis 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. The prosthesis may have a central keel on one end plate and an offset pair of keels on a second end plate. The nucleus may engage a slot or trough in an inner surface of an end plate. The trough can be open on the posterior or anterior end to allow the nucleus to slide into the trough without undue distraction of adjacent vertebrae. The nucleus can be prevented from moving out of the trough by inserting a stop in the trough. | 04-07-2011 |
| 20110166656 | SPINAL IMPLANT CONFIGURED FOR MIDLINE INSERTION - The embodiments provide a spinal implant that is configured for midline insertion into a patient's intervertebral disc space. The spinal implant may have a body and the body comprises one or more apertures. The apertures receive fixation elements, such as a screw and the like. The fixation element may comprise one or more anti-backout features, such as a split ring. In addition, at least some of the apertures are designed to permit a predetermined amount of nutation by a fixation element. The apertures that allow nutation enable the fixation element to toggle from one position to another, for example, during subsidence of the implant in situ. Some of the apertures may be configured to rigidly lock with the fixation elements. Moreover, the spinal implant may include features, such as one or more bores, that can accommodate imaging marks to help guide a surgeon. | 07-07-2011 |
| 20110166657 | SPINAL IMPLANT CONFIGURED FOR LATERAL INSERTION - The embodiments provide a spinal implant that is configured for lateral insertion into a patient's intervertebral disc space. The spinal implant may have a body having a tapered anterior portion and one or more apertures. The tapered anterior portion allows for concomitant distraction of soft tissue during insertion of the implant. In addition, at least some of the apertures are designed to permit a predetermined amount of nutation by a fixation element. The fixations elements that allow nutation enable the fixation element to toggle from one position to another, for example, during subsidence of the implant in situ. | 07-07-2011 |
