Brief Summary
To measure ligamentum flavum thickness in patients with different nationalities, sexes, heights, ages, and weights from Xinjiang Uygur Autonomous Region of China with CT, explore the correlation between various factors and ligamentum flavum thickness, provide reference for pedicle screw placement and lumbar decompression surgery, develop individualized surgical programs, and can effectively reduce the incidence of unnecessary postoperative complications induced by misplacement.
