Selective lumbar decompression and fusion with pedicle screw fixation for the treatment of degenerative scoliosis / 实用医学杂志

ABSTRACT

Objective To investigate clinical effect of local decompression and selective interbody fusion with pedicle screw fixation technique for the treatment of degenerative lumbar scoliosis. Methods Medical records of 122 degenerative lumbar scoliosis patients were retrospectively studied. All cases were treated by selective interbody fusion,local decompression and pedicle screw fixation. Group A(L5 fusion)and group B(S1 fusion)un?derwent imaging analysis,and Suk criteria was used to evaluate the fixation,decompression,bone graft fusion. JOA scores were used to evaluate curative effect of excellent and good rate. Results There were no significant difference in operating time,blood loss and postoperative drainage volume between two groups. Follow?up period for all patients is(16.2 ± 0.8)months. X?ray revealed that Cobb′s angle on the coronal plane,the correction rate of lor?dosis and sagittal Cobb′s angle after treatment,the correction rate of lordosis in group B were better than in group A (P0.05). There was no infection or screw breakage and pulling out. The incidence rate of adjacent vertebral body disease in group A was higher than that in group B(P < 0.05). Conclusions Local decompression and selective interbody fusion with pedicle screw fixation technique for the treat?ment of degenerative lumbar scoliosis can produce satisfactory short to mid?term clinical curative effect.
