    摘要： A cannulated and possibly fenestrated device for injection of material into bone can be dangerous because large, uncontrolled pressures are introduced during injection into a somewhat closed system, and material may extrude undesirably or emboli may be introduced. Methods and devices are described for providing venting of pressure upon injection of material through cannulated and possibly fenestrated screws. The first method involves a bone screw and/or anchor device that includes multiple channels to allow material to flow in through one channel and out through another channel. The second method involves a plunger that can force material into bone if advanced or lessen pressure if withdrawn. The third method involves usage of two separate screws. Material is alternately injected or withdrawn from each screw to cause material to flow from one screw to the other in a controlled way that creates a uniform or asymmetrical distribution of material as desired.

    摘要： A system for planning a spine surgery, comprising a haptic interface capable of providing force feedback to the user and a computer adapted to simulate a surgical procedure by responding to inputs from the haptic interface and outputting haptic feedback to the haptic interface is provided.The system further comprising a rapid prototyping unit including a unit that is adapted to create models of the anatomical region where the surgical procedure will be performed in its current unoperated condition and in the predicted postoperative condition. Further the rapid prototyping unit is adapted to create a three dimensional guide to be used in the surgical procedure as well as suggest revisions to the surgical procedure. The system further comprises a computer that simulates loading of the spine and planned implanted hardware using finite element software.

    摘要： A system and method for bending a surgical rod using an automated bending system includes receiving an indication of a plurality of line segments defined on the rod and an indication of an angle measurement to be formed between at least two adjacent ones of the plurality of line segments. Bending parameters to perform on the rod to form the angle measurement between the at least two adjacent ones of the plurality of line segments are determined and operation of the automated bending system is controlled using the bending parameters to create an angle having the angle measurement between the at least two adjacent ones of the plurality of line segments.
