Abstract
The invention consists of disc replacement implant for the lumbar spine designed for insertion into the disc space via a posterior approach. The implant can be stabilized in the disc space by connection to the vertebra or can be connected to dynamic spinal stabilization device consisting of interconnected bullets nested in a spring nested in a woven sleeve. By controlling the limits of elongation and compression the device prevents movement beyond normal physiological limits. In the midrange of movement flexibility is allowed. A method for using the dynamic spinal stabilization device is also provided.
