Among total 67 postoperative complications resulted from osteotomy of vertebral arch and body in 439 cases of kyphosis, massive bleeding accounted for 2 cases (0.46%); spondylolisthesis, 6 (1.37%); paraplegia caused by compressing of the spinal cord, 5(1.14%); root pain, 6(1.37%); loss of correction, 26(29.55%); leaking and subcutaneous accumulation of CST, 5(1.14%); incision necrosis, 16(3.64%); lifting of luque rod with peneatration through the skin, 1(0.23%). Causes, treatment and prevention of these complications have been discussed in this study. We emphasize that the operation should be done after the stable of ankylosing spondylcitis. The degree of correction by osteotomy at one-level should be limited.
