Abstract: 【Abstract】〓Objective〓To probe the surgical effect of double-segment lumbar spondylolisthesis with transforaminal lumbar interbody fusion(TLIF). Methods〓Eleven cases of lumbar spondylolisthesis were treated with decompression of nerve root and dura, reduction of spinal, reconstruction of vertebral canal, pedicle screw fixation and fusion by TLIF. The Lenke grading system was used to assess the spinal fussion. The Henderson grading system was used to assess the clinical effect. Results The reduction of the spondylolisthesis was satisfied in all cases based on a follow-up of 1-2 years. The spinal fusion: A grade in one cases, B grade in one case. The clinical effect showed excellent in 9 cases, good in one case, poor in one case. Conclusion〓The application of TIIF in the treatment of patients with double-segment lumbar spondylolisthesis can provide successful interbody fusion and clinical results.
