Results: The main spinal postoperative complications includes: spinal stenosis(n=33, 21 cases of epidural fibrosis, 13 cases of epidural hematoma or epidural abscess); lack of stability(n=43); infection(n=23, 7 cases of para-spinal soft-tissue infection, 5 cases of vertebral discitis, 4 cases of vertebral and appendix infection, 3 cases of epidural abscess, 2 cases of myelitis, 2 cases of spinal arachnoiditis) and other(n=28, 12 cases of inner fixation failure, 9 cases of epidural hematoma, 7 cases of cerebrospinal fluid gusher).
