Abstract |
Objective: The aim of this study was to examine the association of disc degeneration, disc space narrowing and postoperative low back pain in patients who underwent microscopic discectomy.
Methods: Sixty patients with lumbar disc herniation at L4-5 level who were treated by microscopic discectomy from February 2001 to November 2003 were investigated in this study. They were all male patients with an average age of 41.1 years old.
The degrees of disc degeneration were measured through T2-weighted magnetic resonance image and divided into 4 groups. The disc heights were measured before and 1 year after the surgery using simple lateral X-ray. Then, we analyzed the relationship between disc degeneration, disc space narrowing and low back pain. Statistical analysis was performed with chi-square test.
Results: Disc space narrowing 1 year after the surgery was severe in the IV and V grade group of lumbar disc degeneration, and more severe postoperative back pain was reported in the IV and V grade group(p<0.05).
Conclusion: In patients who underwent microscopic discectomy as one level disc herniation, more lumbar disc degeneration showed disc space narrowing after surgery were significant, and more LBP was reported. Nevertheless, long-term follow up is necessary. |
