    摘要： A device for stabilizing at least a portion of the spinal column, including a longitudinal member sized to span a distance between at least two vertebral bodies and being at least partially formed of a shape-memory material exhibiting pseudoelastic characteristics at about human body temperature. A number of bone anchors are used to secure the longitudinal member to each of the vertebral bodies. The longitudinal member is reformed from an initial configuration to a different configuration in response to the imposition of stress caused by relative displacement between the vertebral bodies, and recovers toward the initial configuration when the stress is removed to thereby provide flexible stabilization to the spinal column. During reformation of the longitudinal member, at least a portion of the shape-memory material transforms into stress-induced martensite. In a particular aspect of the invention, the longitudinal member is a plate having a central portion at least partially formed of the shape-memory material, and a pair of connection portions disposed at opposite ends of the central portion for connection to each of the vertebral bodies. The central portion of the plate defines a number of alternating ridges and grooves along a length thereof having an initial amplitude corresponding to the initial configuration and a different amplitude corresponding to the different configuration.

    摘要： A vertebral rod for stabilizing a patient's spine. The rod may include an elongated body with first and second ends and have an elongated cross-sectional shape with a major axis and a minor axis and a centroid positioned at an intersection of the axes. First and second longitudinal channels may extend through the body. The channels may be spaced apart and contained within the body. The body may have a first flexural rigidity along the major axis and a different second flexural rigidity along the minor axis.

    摘要： The present invention relates to a brace installation instrument placement that is mounted to anchors secured in an animal subject. The installation instrument includes anchor extensions coupled to the anchors. The instrument is movable with respect to the anchors to position a brace in a position more proximate the anchors. The brace can be indexed for insertion at a predetermined orientation with respect to the installation instrument. Methods and techniques for using the installation instrument are also provided.
