Neglected knowledge: Asymmetric features of lumbar disc disease

Abstract

Background: Lumbar disc herniations have been extensively studied in the literature. Asymmetric trunk muscle anatomy could affect the development of this entity which has never been quantitatively studied previously. The purpose of this manuscript was to analyze the operated sides of herniated lumbar disc. Materials and Methods: Data files of patients with lumbar disc herniation operated in author's hospital between January 2007 and March 2009 were analyzed. Results: In operated side analysis, discectomy side was 53% on the left side, 40% on the right side, the difference between two sides was statistically significant. Conclusion: The asymmetric distribution may be a significant factor in the development and surgical treatment of lumbar disc herniations.
