Transverse cavity device and method
First Claim
Patent Images
1. A method of creating a transverse cavity in a bone having a compression fracture, comprising the steps of:
- identifying a surface in a bone that is to be restored to its normal anatomical position, said surface generally defining a transverse plane;
inserting a tool having a tool body area into the bone adjacent said surface;
after insertion, activating a movable element operably supported by said tool in a direction outwardly from said tool body and through a path consisting essentially of a substantially flat plane that is substantially parallel to said surface to define a transverse cavity having an area greater than said tool body area and a substantially uniform height in a direction generally perpendicular to said transverse plane.

Abstract
The invention teaches the use of a surgical instrument for creating and preparing a cavity in a bony intervertebral body. Asymmetrical cutting structures selectively open a cavity which has a relatively large surface area in the vertical direction.
