Abstract: A dilator system includes a series of sequential dilators. A first dilator has an elongated body having a major axis and a minor axis, the minor axis being substantially normal to the major axis. A second dilator has an elongated body having a major axis and a minor axis, the minor axis of the second dilator being substantially normal to the major axis of the second dilator. A bore of the second dilator is configured to matingly receive the first dilator in such a way that the major axis of the second dilator is aligned with the minor axis of the first dilator and the minor axis of the second dilator is aligned with the major axis of the first dilator.

Abstract: An expandable interspinous process spacer implant for insertion and/or implantation between a spinous process of a superior vertebral body and a spinous process of an inferior vertebral body, the implant comprising multiple pairs of legs joined in a scissor-like fashion and pivotally coupled to each other by one or more pins, where each leg has multiple slots along its longitudinal axis. The implant further may include a pair of bearing surfaces coupled between the legs via cross pins and a first plate and second plate each of which is coupled to a pair of roller pins disposed between a pair of slots on the legs where rotation of a fastener in the fastener holes of the first and second plate results in the first plate and the second plate being drawn toward each other causing the expansion of the height of the implant.

Abstract: A surgical instrument for moving a clamp relative to a bone anchor to properly position and secure the clamp to the bone anchor. The surgical instrument including a housing, a socket assembly, a manipulating assembly, a gripping assembly and a reduction assembly.

Abstract: A vertebral adjustment system configured to move individual vertebral bodies relative to the other vertebral bodies to thereby realign the spine. The system may include a frame, and a plurality of alignment devices coupled to the frame and to the individual vertebral bodies. By manipulated the alignment devices the vertebral bodies to which they are attached may be moved.
