Abstract: A plate of biocompatible material is provided having curvature in two planes such that it conforms to the curvature of the L5 vertebral body and to the patient's lordotic curve. Holes are provided receiving screws for anchorage in the vertebral body and sacrum. A flange or foot portion on the plate provides a wider base end area for support in the L5-S1 interspace. The foot portion is also arranged for appropriate entry angle of screws into the sacrum such as to improve anchorage in the sacrum. Anti-backout and low profile features are incorporated. The anterior lumbar plate is situated to maintain the anterior interbody bone graft in compression by resisting tensile forces during extension.

Abstract: An intervertebral implant includes a body having an upper surface, a lower surface and a transverse fastener hole. The body includes a dynamic fixation mechanism for seating a fastener in the fastener hole and translating the fastener relative to the implant to accommodate subsidence of the implant. In one embodiment, an implant includes a transverse slot with an elongated seat for translating a seated fastener relative to the implant. In another embodiment, an implant includes a displaceable sliding member for translating a fastener relative to the implant.

Abstract: An intervertebral implant includes a first plate and a second plate that is configured to be moveably engaged with the first plate along an axis of translation. Each plate defines at least one hole or recess for receiving a fastener that is configured to be fastened to a respective vertebrae. In one embodiment, a toothed surface is defined on both the first plate and the second plate. The toothed surface of the first plate is configured for engaging the toothed surface of the second plate such that translation of the second plate with respect to the first plate is limited in a single direction along the axis of translation.

Abstract: A spine implant system having two or more adjacent segments that have a male-female annular interlocking relationship for increased mechanical stability and resistance to relative translation and rotation. One or more segments is provided with at least one perforation channel or void to promote osteo-induction within the segment. Optionally, two adjacent segments have at least one common or aligned perforation channel or void. Two or more spaced apart portions of a segment surface are optionally chamfered to provide easier fabrication and/or positioning of the segment. Two spaced apart exposed surface planes of an interlocked segment pair optionally are axially oriented at a small positive angle relative to each other, to approximate natural spine curvature. Segments in some embodiments have a curvilinear delta cross sectional shape and/or have crosshatched grooves in exposed surfaces. Many of the embodiments are useful in transforaminal lumbar interbody fusion (TLIF).

Abstract: Various embodiments of the present invention relate to an apparatus for vertebral body replacement and methods associated therewith. In one embodiment, a vertebral body replacement apparatus may be used to correct and stabilize the spine (e.g., the thoracolumbar spine (T1-L5)). In another embodiment, a vertebral body (e.g., a diseased and/or damaged vertebral body) that has been resected or excised (e.g., for the treatment of a tumor or trauma) may be replaced (with the height of the resected or excised vertebral body being substantially replaced and restored by the apparatus of the present invention).

Abstract: An interbody fusion device for engagement between vertebrae includes a pair of lateral spacers for spacing the vertebrae, and a connecting member adapted to couple together the lateral spacers when inserted between the vertebrae. The connecting member, individual lateral spacers, or the entire spinal spacer can be made of bone in order to promote fusion of the vertebrae. The modular construction permits use of bone segments otherwise unsuitable due to size or strength in stable fusion devices.

Abstract: The invention relates to an orthopedic fixation device with an at least partly shaft-like fixation member, a shaft-like mounting body, and a transverse support securing the fixation member and the mounting body in a position in which they are laterally offset from one another. In order to adjust the transverse support without having to change the position of the fixation member, the fixation member can be rotated about its longitudinal axis in the transverse support and can be secured in a defined angular position.

Abstract: The invention relates to an orthopedic fixation device for securing a rod-like fixation element, with two clamping jaws which can be moved relative to one another and which, when brought together, clamp the fixation element between them. In order to permit space-saving configurations of a fixation device that can be introduced and operated through small orifices in the body, a cam body is provided which is mounted on the fixation device so as to be able to rotate next to the clamping jaws in the direction of tightening and which, when rotated, pushes one clamping jaw toward the other.
