METHODS: The lumbar spine magnetic resonance imaging studies of 52 subjects with CLSS and 48 control subjects were retrospectively evaluated. In each examination, the five lumbar levels were assessed for the presence or absence of circumferential or shallow annular bulges, annular tears, anterior or posterior disc herniations, epidural lipomatosis, Schmorl's nodes,spondylolisthesis, pars defects, and stress reactions of the posterior vertebral elements. RESULTS: Compared to control individuals, subjects with CLSS exhibited increased incidence of circumferential and shallow annular bulges, annular tears, discherniations and spondylolisthesis(P < 0.05). CONCLUSION: CLSS is associated with increased incidence of degenerative changes in specific osseous and soft-tissue elements of the lumbar spine.展开更多

However, multi-level lumbar spondylolysis is rare and accounts for less than 6% of lumbar spondylolysis. We report a case of three-level lumbar spondylolysis with single-level spondylolisthesis. A 47-year-old woman presented to us with low back pain for 9 years that progressively worsened and the pain was exacerbated with standing and walking. She was diagnosed with three-level lumbar spondylolysis at L3-5 and spondylolisthesis at L4. We performed posterolateral lumber fusion (PLF) and posterior lumbar interbody fusion (PLIF) surgery for her. During the same period, pain recovery and fusion rate of the patient were evaluated after surgery. The results were favorable and proved the efficacy of combining PLF and PLIF technique for treatment for three-level lumbar spondylolysis and single-level spondylolisthesis.展开更多
