Despite intensive conservative treatment, severe kyphotic spinal deformities may develop in patients with ankylosing spondylitis. Lumbar osteotomy can restore a horizontal visual field in these patients. Of 50 patients undergoing corrective lumbar osteotomy, there were 44 men and 6 women. A transpedicular screw and cable system was used in 37 patients. Mean correction of deformity was 38.7 degrees. Mean loss of correction was 4.8 degrees, but was 15 degrees in those cases in which transpedicular fixation was not used. All patients were able to see straight ahead after the operation. There were 2 deaths and 1 permanent sacral root lesion. Fixation failure was seen in 2 of 37 patients in whom transpedicular implants were used and in 3 of 13 in whom alternative methods of internal fixation were used.
尽管进行了强化保守治疗，但强直性脊柱炎患者仍可能出现严重的脊柱后凸畸形。腰椎截骨术可恢复这些患者的水平视野。在接受腰椎矫正截骨术的50例患者中，男性44例，女性6例。37例患者使用了椎弓根螺钉和缆线系统。畸形的平均矫正角度为38.7度。矫正丢失的平均角度为4.8度，但在未使用椎弓根固定的病例中为15度。所有患者术后均能直视前方。有2例死亡和1例永久性骶神经根损伤。在使用椎弓根植入物的37例患者中有2例出现固定失败，在使用其他内固定方法的13例患者中有3例出现固定失败。
