29-3-11, 54F LSTL3-4-5-S1

54 year-old-female, 6m LBP & L5 left leg pain. MRI demonstrate LSS L3-4,L4-5 and HD L5-S1, but on Xray it less stenosis than MRI. Actually, after decompressing flavum ligment, I did see the compression such as MRI at L5-S1 . This case I think that I dont need compress the L3-4 .
