Purpose to compare posterior decompression and internal fixation and posterolateral fusion, posterior decompression and internal fixation and posterior intervertebral fusion in the treatment of low-alcohol pros and cons of spondylolysis type lumbar olisthe disease. Methods retrospective analysis our department between September 2008 and June 2008 were analyzed in 36 patients, 19 cases treated by posterior decompression and internal fixation and posterolateral fusion (as A group) and 17 cases with posterior decompression and internal fixation and posterior intervertebral fusion treatment (group B). Group A (19 cases), with an average age of 51, 17 cases slippage parts for L5, 2 cases of L4; 17 cases of group B, with an average age of 49 years old, and there are 13 cases of slippage parts for L5, 4 cases of L4. According to Meyerding degree, the selected 36 cases are no more than Ⅱ degrees. Results follow-up 6 ~ 21 months time, patient satisfaction and clinical efficacy of group A was 100% (19/19); Group B clinical curative effect satisfaction rate 88.2% (15/17). In operation time, intraoperative bleeding, blood transfusion amount, surgical complications, group A is better than that of group B, there was no difference in clinical efficacy of two groups, slip Angle recovery is group B than in group A. Conclusion in the treatment of low-alcohol spondylolysis type lumbar olisthe disease, posterior decompression and internal fixation is better than that of posterior decompression and internal fixation and posterolateral fusion and posterior intervertebral fusion.
