Abstract
Methods of securing an implant within an intervertebral disc are provided. In some embodiments, systems for minimally invasive disc augmentation include an anulus augmentation component and a nucleus augmentation component. Both are suited for minimally invasive deployment. The nucleus augmentation component restores disc height and/or replaces missing nucleus pulposus. The anulus augmentation component shields weakened regions of the anulus fibrosis and/or resists escape of natural nucleus pulposus and/or the nucleus augmentation component. Methods and deployment devices are also disclosed. Methods of closing a defect in an anulus fibrosus of an intervertebral disc using a barrier are also provided.
Claims20
A method of securing an implant within an intervertebral disc comprising the steps of:
- providing a biocompatible support member adapted for implantation within the intervertebral disc, wherein said annulus comprises a defect;
- wherein the defect is bordered by an outermost layer of the annulus and an innermost layer of the the annulus;
- providing at least one bone anchor;
- implanting the biocompatible support member entirely beyond the defect and positioning said support member entirely against the innermost lamella of the annulus to close said defect;
- positioning said at least one bone anchor in the defect;
- anchoring the biocompatible support member with said at least one bone anchor to at least one of an upper or lower vertebra along an endplate.
