2) The lesion sites of reoperated cases were L4-5 space(68.8%), L5-S1 space(18.8%), multiple space(9.4%) and L3-4 space(3.1%) in orders. 3) The symptom-free interval between 1st and 2nd operation were 1-5 years(34.4%), 6-10 years(15.6%) and 2-6 months(12.5%) in orders. The longest interval were above the 11 years (21.9%) and the shortest interval were below the 1 month(15.6%). 4) The main pathologic findings of reoperated 32 cases were epidural fibrosis(31.2%), incomplete disc removal+epidural fibrosis(31.2%), new disc herniation(21.8%), foraminal stenosis(9.4%) and opposite site herniation(6.3%) in orders.
