Abstract
A power tool for removing an intervertebral disc and preparing vertebral endplates is described. The power tool may include a cutting element, and the height of the cutting element may be adjustable. The cutting element may be a braided cable and may include one or more beads to enhance the effectiveness of the cable. The cutting element may have a minimum height requirement, which may not be satisfied in patients with a collapsed disc due to degenerative disc disorder. For these patients, also described are bone tamps for increasing the intervertebral distance and providing access to tissues distal to the tamp. One type of bone tamp features an inflatable balloon with an inner lumen. Another type of bone tamp includes an expanding distal end and an inner cannula. Also described is a manual expander scraper tool that is compatible with both types of bone tamp.
