  Object: Previous reports have indicated that the level of lumbar spinal canal stenosis (LSCS) often differs from that diagnosed from neurological symptoms, and L5 nerve roots are often affected by stenosis at the L2–L3 or L3–L4 level; however, few cases have been describ Decompression surgery for upper lumbar spinal canal stenosis (LSCS) of L2–L3 and L3–L4 causing L5 and S1 symptoms was investigated. Methods: Eight patients with a diagnosis based on L5 or S1 symptoms, but whose MRI or CT-myelography showed only one level of stenosis at L2–L3 or L3–L4 were studied. The level of stenosis was determined by the most narrowing lesion, such as total or subtotal block on CT-myelography and MRI. Selective nerve root block was performed to determine which nerve root was the origin of the pain in these patient.. Read More»
