Changes in disc height index (DHI) after surgery. The operated discs showed a slow, progressive decrease in disc height over time. The DHI in the 16G puncture and annulus defect groups were significantly lower than in the control group (*P < 0.01 vs. control group). The DHI of the PLGA/fibrin gel implantation group was significantly higher than that of the 16G puncture group and annulus defect group over 6 months (# P < 0.05 vs. 16G puncture group or annulus defect group)
