Objective: Spinal surgery procedures for disc herniation can be complicated by two major problems: (1) re-herniation through the annulus fibrosus defect and (2) painful degeneration of the spinal segment. Therefore, we examined a textile absorbable polymer-based biomaterial for its utility to seal annulus[for full text, please go to the a.m. URL]
