MATERIALS, DEVICES, AND METHODS FOR IN-SITU FORMATION OF COMPOSITE INTERVERTEBRAL IMPLANTS

摘要

An intervertebral disc repair devices is disclosed that includes a porous matrix and a polymerizable material. The intervertebral disc repair device is advantageous because it may be injected through a small annulus defect, it can form an implant larger than the annulus defect for improved expulsion resistance, it has increased toughness and durability because of the porous matrix, and it conforms to the partially or fully evacuated disc space during insertion or packing.
