Eleven patients with ankylosing spondylitis had severe disabling kyphosis with forward bending of the upper part of the spine. The kyphosis was corrected by osteotomy by removal of a wedge composed of the spinous processes and the neural arch of the second lumbar vertebra and by excision of bone from the inside of the posterior part of the vertebral body of L2. By hyperextending the spine, a wedge fracture occurs in the vertebral body, producing lordosis and correction of the deformity without an anterior opening of the lumbar discs.
11例强直性脊柱炎患者有严重致残性脊柱后凸，脊柱上部向前弯曲。通过截骨术矫正后凸，方法是切除由第二腰椎棘突和神经弓组成的楔形骨块，并从L2椎体后部内侧切除骨质。通过脊柱过伸，椎体发生楔形骨折，产生前凸并矫正畸形，而无需打开腰椎间盘前方。
