METHODS AND APPARATUS FOR PLACING INTRADISCAL DEVICES

摘要

An osteotomy of a portion of a vertebral endplate and/or vertebral body allows for easier insertion of a device (502) that fits tightly into a disc space. A different aspect of the invention resides in a mechanical device (506) to hold the osteotomized portion of the vertebra against the vertebral body after the intradiscal device is placed. The device may be removed after the pieces of vertebra heal and fuse together.
