Patent number: 9968382Abstract: A spinal stabilization system may include a pair of structural members coupled to at least a portion of a human vertebra with connectors. Connectors may couple structural members to spinous processes. Some embodiments of a spinal stabilization system may include fasteners that couple structural members to vertebrae. In some embodiments, a spinal stabilization system, provides three points of fixation for a single vertebral level. A fastener may fixate a facet joint between adjacent vertebrae and couple a stabilization structural member to a vertebra. Connectors may couple the structural members to the spinous processes of the vertebrae. Use of a spinal stabilization system may improve the stability of a weakened or damaged portion of a spine. When used in conjunction with an implant or other device, the spinal stabilization system may immobilize vertebrae and allow for fusion of the implant or other device with vertebrae.Type: GrantFiled: March 29, 2017Date of Patent: May 15, 2018Assignee: Zimmer Spine, Inc.Inventors: Margaret E.

Patent number: 8292959Abstract: A spinal implant may be used to stabilize a portion of a spine. The implant may promote bone growth between adjacent vertebrae that fuses the vertebrae together. An implant may include an opening through a height of a body of the implant. The body of the implant may include curved sides. A top and/or a bottom of the implant may include protrusions that contact and/or engage vertebral surfaces to prevent backout of the implant from the disc space. A variety of instruments may be used to prepare a disc space and insert an implant. The instruments may include, but are not limited to, a distracter, a rasp, and one or more guides. The implant and instruments may be supplied in an instrument kit.Type: GrantFiled: August 11, 2010Date of Patent: October 23, 2012Assignee: Zimmer Spine, Inc.Inventors: Scott A. Webb, Anthony P.

Patent number: 7833271Abstract: A spinal implant is provided which maintains intervertebral spacing and stability within the spine. The spinal implant may include a body and an insert. The body of the spinal implant may be formed of a ceramic material. In some embodiments, the body may be formed of beta tricalcium phosphate. The body may include an opening that is complementary to the insert. The insert may fit within the opening. The insert may include a number of passageways. Some of the passageways may intersect to form a scaffold for bone growth. Bone growth promoting material may be introduced into the insert before the insert is positioned in a body and inserted in a patient between two vertebrae.Type: GrantFiled: May 4, 2004Date of Patent: November 16, 2010Assignee: Zimmer Spine, Inc.Inventors: Margaret E.

Publication number: 20040133279Abstract: A spinal implant is provided which maintains intervertebral spacing and stability within the spine. In some embodiments, two or more spinal implants may interlock to form a spinal stabilization system. Spinal implants may interlock using protrusions, indentations, teeth, and/or grooves. In an embodiment, an opening may be positioned in the spinal implant to fuse the spinal implant to surrounding bone tissue. Bone growth through the opening may be increased by using a removable bone growth stimulating insert in the opening. A spinal implant may be constructed of biocompatible material, for example, bone, metal, and/or polymers.Type: ApplicationFiled: January 6, 2003Publication date: July 8, 2004Inventors: David J.
