OBJECTIVES: Lumbar spine single level unstable @entity528 was treated with unilateral decompression, disc excision, posterolateral interbody fusion utilizing single BAK cage and count-lateral facet joint screw fixation. The short-term and mid-term clinical results were evaluated. METHODS: There were thirty @entity1 (13 male, 17 female) with an average age of 46.5 years. From posterior approach, all @entity1 underwent unilateral decompression, disc excision, interbody fusion with posterolateral inserted single BAK cage, and count-lateral facet joint screw fixation. RESULTS: All @entity1 underwent surgery safely without severe @entity532 occurred such as @entity16 . The average follow-up time was 12 months (6 - 18 months) with complete relief of symptoms. Solid fusion was achieved in all but 2 @entity1 at final follow-up. 90% of the @entity1 obtained successful clinical outcome. CONCLUSIONS: Complete decompression of the neural foramen can relief the symptoms, and interbody fusion utilizing threaded cage can restore the height of disc space and withstand axial loading of the spine. Addition of the facet joint fixation increased the postoperative segment stability and enhances solid fusion. With less invasive and preservation of part of the posterior elements of the lumbar spine and the solid fusion achieved, we consider it a sound procedure for the treatment of single level unstable @entity528 of lumbar spine. Long-term follow-up results needs to be observed.
