Abstract

See full text

A process for repairing the annulus fibrosus, and replacing the nucleus pulposus. Removal of the nucleus pulposus and only as much of the annulus fibrosus and intervertebral disk as is necessary is performed. The tissue so removed is replaced by a material which is resilient, but non-dispersing upon setting. After application of the material, and after the material is set, the resiliency of the material permits motion of the vertebrae and performs the cushioning and joint functions of the intervertebral disk. The material is physiologically acceptable to the human body.
