| 20090254125 | Top Loading Polyaxial Spine Screw Assembly With One Step Lockup - A top loading polyaxial spinal rod screw assembly is configured for simultaneous or one step lockup of angular orientation of a rod holder portion of the screw assembly relative to a bone screw and of a spinal rod within the rod holder portion of the screw assembly. The spinal rod and the angular orientation of the rod holder holding the spinal rod are thus fixed upon receipt of a lockup component of the present assembly. Components of the present spinal rod screw assembly cooperate to allow reception of a spinal rod in a rod holder that is adapted for pivotal retention on a bone screw and to lock or fix the spinal rod within the rod holder while also locking or fixing the angular orientation of the rod holder relative to the bone screw upon receipt of a lockup cap component of the screw assembly in the rod holder. In one form, the present screw assembly is defined by a three-piece polyaxial screw head assembly for a bone screw. The three-piece polyaxial screw head assembly includes a spine rod holder or head configured for pivotal connection with the bone screw, a head insert configured for reception in the spine rod holder, and a lockup (end) cap configured for reception in the spine rod holder. The lockup cap is configured to interact with the head insert to fix an angular position or orientation of the spine rod holder relative to the bone screw at the same time as fixing a spinal rod that has been received in the spine rod holder relative to the spine rod holder. | 10-08-2009 |
| 20090326592 | Posterior Spinal Prosthesis - A posterior spinal prosthesis is configured to cover exposed portions of a spinal column especially, but not necessarily, as a result of a medical spinal procedure and particularly, to provide posterior coverage of an exposed spinal cord, soft tissue, Foramen and/or adipose tissue, associated with one or more vertebrae as a result of the removal the spinous processes and/or the spinous process and laminar hoods from the one or more vertebrae of the spine as a result of a spinal decompression procedure or other reason. A plate forming the prosthesis is connectable to spine rod constructs implanted on lateral sides of the vertebrae and projects in the posterior direction relative to the connection. The plate is generally curved in the superior/inferior direction to provide either a lordotic or kyphotic curvature depending on the portion of the spine to which the prosthesis is utilized. As such, the posterior spinal prosthesis may be used on any portion of the spine such as the cervical vertebrae, the thoracic vertebrae and/or the lumbar vertebrae. The present posterior spinal prosthesis also provides posterior stabilization of the associated vertebrae as well as aiding in preventing post operative soft tissue cavitation at the decompression site. | 12-31-2009 |
| 20100160981 | Posterior Cervical Cross Connector Assemblies - A spinal cross connector head assembly and a cross connector assembly utilizing the spinal cross connector head assembly are configured for fixation to an existing spinal rod bone screw head. The spinal cross connector head assembly has one or more components which incorporate one or more breakaway portions that aid in the installation of the cross connector head assembly onto a polyaxial spinal rod bone screw assembly. The spinal cross connector assembly includes first and second spinal cross connector head assemblies each of which is configured for fixation to existing, adjacent spinal rod screw heads and connection with a cross connector rod. Each spinal cross connector rod head assembly has a dual breakaway system including a cross connector head component having a breakaway collar that, once detached, provides a polyaxial cross connector head, and a set screw component having a breakaway set screw that, once detached, provides fixation of the orientation of the polyaxial cross connector head relative to the polyaxial spinal rod bone screw head. | 06-24-2010 |
| 20100217322 | Posterior Spinal Bridge Assembly Providing Static or Dynamic N-Level Spinal Bridge Interconnection - A bio-compatible posterior spinal bridge assembly provides static or dynamic N-level spinal bridge interconnection between adjacent posterior spinal bridges and posterior spinal bridge assemblies. The posterior spinal bridge assembly includes a spinal bridge that is received in posterior vertebral screw assemblies that are affixed a vertebra and to laterally span the posterior side of the vertebra, and an interconnection element that allows static or dynamic connection between adjacent spinal bridges and/or spinal bridge assemblies. The interconnection element is defined by interconnection members that are carried by the spinal bridge and which provide static or dynamic connection between any number of adjacent spinal bridges/bridge assemblies. The interconnection members are attachable at various positions along the spinal bridge such as medially, laterally, or midline on the spinal bridge. Adjacent spinal bridge assemblies may thus be statically or dynamically linked, connected or coupled to one another via the interconnection members when more than one spinal bridge assembly is used. | 08-26-2010 |
| 20110106168 | Laminoplasty Rod System - A laminoplasty rod and rod system that allows for variable angulation, translation (distraction and/or compression) and rotation of a spinal lamina bone portion associated with a laminoplasty, prior to fixation thereof. The laminoplasty rod is configured for use with a polyaxial spinal rod bone screw assembly that is adapted to be anchored to the vertebra associated with the laminoplasty, and is attachable to the spinal lamina bone portion. The laminoplasty rod system provides positional attachment of the laminoplasty rod to the spinal components associated with the laminoplasty and fixation thereof in various orientations. The laminoplasty rod system is characterized by a configured laminoplasty rod that fits into or onto the head of a polyaxial spinal rod bone screw assembly. A bone screw boss, defining a bone screw attachment configuration, is formed at one end of the laminoplasty rod. Preferably, but not necessarily, the bone screw boss is situated at an angled end of the rod having a pre-defined bend that provides for greater variation in rod orientation. | 05-05-2011 |
| 20110313458 | Spinal Clips For Interspinous Decompression - A spinal clip for creating a potential space within the spinal canal and thus stabilizing the spine without the need for additional spinal components is embodied in different forms. The spinal clips are configured to provide a clamping or holding force against and/or to the spinous processes, transverse processes and/or the lamina of adjacent vertebrae. In one form, the spinous process clips utilize pivoting to effect clamping or holding. In another form, the spinous process clips utilize rotation to effect clamping or holding. Such rotation may be between clamping or holding members or via a screw system. In yet another form, the spinous process clips utilize ratcheting to effect clamping or holding. In a still further form, the spinous process clips utilize expansion to effect clamping or holding. Depending on the form of clamping or holding, the spinous process clips can provide infinite adjustment of the clamping or holding force within an adjustment range, or provide discrete steps or levels of the clamping or holding force. | 12-22-2011 |
| 20110313466 | Spinal Facet Bone Screw System - A spinal facet bone screw system provides tactile feedback to the user during installation to aid in determining when one or more components of the spinal facet bone screw system have been installed or implanted. The spinal facet bone screw system has a spinal facet screw and a washer. Tactile installation feedback is provided at an interface between a friction surface of the head of the spinal facet screw and a friction surface of the pocket of the washer to determine when the spinal facet screw has reached its full insertion depth. The bottom or undersurface of the washer that abuts a spinal facet bone or other spinal component during installation may be configured and/or textured to further provide tactile installation feedback as between the washer and the bone or other spinal component. | 12-22-2011 |
