[Short-term therapeutic effect of posterior pedicle screw fixation for treatment of degenerative lumbar scoliosis]

OBJECTIVE: To evaluate the short-term outcomes of patients receiving orthopedic surgery with posterior pedicle screw fixation for degenerative lumbar scoliosis. METHODS: Between March, 2006 and August, 2009, 36 patients with degenerative lumbar scoliosis (19 males and 17 females) underwent procedures of decompression, bone implantation and pedicle screw fixation. Fifteen patients were also treated by PLIF and 21 cases received posterior-lateral fusion. The JOA scores, Oswestry disability index (ODI), and Cobb angle were recorded before and after the operation, and the surgical complications were also observed. RESULTS: The JOA scores increased significantly by 83.3% after the operation (P<0.05). The procedures resulted in significantly lowered ODI from (67.1-/+11.4)% before the operation to (32.1-/+10.8)% after the operation (P<0.01). A significant improvement of the coronal Cobb's angle was achieved after the operation (26.7 degrees preoperatively vs 12.3 degrees postoperatively, P<0.01), and the lordosis angle was improved from 10.7 degrees to 36.6 degrees after the operation (P<0.01). All the patients were followed up for 12 to 50 months (mean 38 months), and no implant loosening, displacement or fragmentation, or pseudarthrosis was found at the final follow-up. CONCLUSION: Posterior pedicle screw fixation shows good short-term therapeutic effect in treatment of degenerative lumbar scoliosis. Individualized surgical plans and adequate preoperative evaluation are keys to successful operations Keywords : Aged,Aged,80 and over,Bone Screws,China,complications,Decompression,Surgical,Female,Humans,instrumentation,Lordosis,Lumbar Vertebrae,Male,methods,Middle Aged,Orthopedic Procedures,pathology,Pseudarthrosis,Scoliosis,surgery,Treatment Outcome,, Therapeutic,Effect,Posterior,Pedicle, can reflexology help back pain
