Abstract

We have operated on 13 Patients with Spondylolisthesis over recent 3years. The age of Patient was from 4th decade to 7th decade, with the largest number in 6th decade. The method of operation were Posterior lumbar interbody fusion(PLIF) in 7 cases, anterior interbody fusion in one case, Harrington application in one cases, Facet joint reconstruction with wiring in one case, PLIF+ Harrington in one case, and Roy-Camille Pedicular screw in 2cases. The result of operation were considered excellent in 8cases, fair in 4cases and poor in one case. On the selection of operating method for the patients with spondylolisthesis, we suggest that. 1) In cases of the isthmic type or dysplastic type without disc protrusion, one method among bilateral intertransverse fusion, fixation by wiring, or Harrington rod application could be used. 2) In case that extensive laminectomy is needed such as associated with spinal stenosis or disc protrusion, PLIF is considered to be good method. 3) If displacement is severe(especially in case of severe unstable spine due to spinal trauma), pedicular screw could be placed because it can reduce and immobilize the displaced spine. 4) In cases of simple spondylolysis or mild spondylolisthesis with isthmic defect, if symptom is continued, bone graft in the defect area and fixation by wiring is good method.
