Objective : Spondylolisthesis has become one of the major causes of the lower back pain in the orthopedic field. We wanted to compare the radiological change with before & after treatment including constitution-acupuncture on spondylolisthesis. Methods : This study were carried out on 9 patients with spondylolisthesis. We reviewed medical records and radiological films. We studied rating score, percent of slip, sagittal angle, percent of posterior disc height. Results and conclusions : The improvement index showed 0.04, 030, 033, 0.00, 0.32 points in isthmic type, and 0.55, 0.56, 0.53, 0.00 points in degenerative type. The percent of slip for pre/post-treatment showed 20/20, 12/11, 24/20, 30/30, 4/3 percents in isthmic type, and 12/4, 16/11, 13/9, 8/8 percents in degenerative type. Sagittal angle showed 11/11, 15/12, 21/18, 17/15, 21.19 degrees in isthmic type, and 22/21, 19/15, 2/2, 8/9 degrees in degenerative type. Percent of posterior disc height were 17/18, 26/28, 24/25, 22/23, 25/27 in isthmic type, and 29/33, 37/45, 25/31, 24/24 in degenerative type. The result suggest that constitution-acupuncture and conservational treatment are good method for treatment of spondylolisthesis, and especially in degenerative type.
