Abstract:
We have analyzed clinical results of forty-five patients who had spondylolisthesis which were operated using transpedicular screw fixation devices (CD or Steffee VSP system) between June, 1987 and March, 1992 at the department of Orthopedic Surgery of Kwang-ju Christian Hospital. Simultaneously we compared the postoperative results between two groups. The results were as follows: 1. The ratio of man and woman was 1: 2.2 and mean age was 44.3 years (44.8 years in degenerative type and 42.5 years in isthmic type). 2. The most common level was L4 on L5 and two-third of all cases were isthmic type. 3. The clinical results were satisfactory in 91% (41 cases) according to anthors modified evaluation system. There was no significant difference between degenerative and isthmic type. 4. The mean % of slip was improved from 23.3% preoperatively to 7.4% postoperatively and the mean slip angle was improved from 3.5 degrees preoperatively to-5.4 degrees postoperatively. 5. The devices which were used for operation were C-D instrument in 21 cases and Steffee VSP system in 23 cases. There was no difference in radiographic examinaton and clinical result between two groups. 6. The anterior fusion was done for 9 active young patients. The results were significantly satisfactory. 7. We consider the transpedicular fixation system is the most recommandable method of treatment for spondylolisthesis in providing excellent reduction of slippage and maintenance of reduction with rigid fixation device.
