Abstract: Various embodiments of a vertebral tension band assembly and associated connection structure are provided. The tension band assemblies may be attached to vertebral bodies to, for example, connect one vertebrae to another, retain the band in approximately a preferred position by application of tension to the band during insertion and/or limit, impede, inhibit, reduce or interfere with the separation from one vertebra to another and may further block, impede, interfere with, inhibit, reduce or present an obstacle to dislodgement of a spinal implant from between the vertebrae to which it is attached. Flexible band portions of the assemblies may be treated and/or configured to promote bony integration between the band and the associated vertebrae, limit tissue adhesion to the band, and/or to elute a therapeutic substance from the installed band to the surgical site.

Abstract: Embodiments of an adjustable rasping tool for use in orthopedic medical procedures are disclosed. In certain embodiments, a body having two arms extending from a base and a tip portion on each arm is provided, with a shaft between the arms connected to a handle that is rotatably coupled to the base of the body. The shaft has an extended distal portion that contacts the tip portions of the arms. As the shaft is moved proximally (e.g. by rotating the handle in a given direction), the extended distal portion moves with respect to the tip portions and forces them apart. Methods for using embodiments of the disclosed structure are also described.
