摘要
A method for pre-planning the amount of surgical correction of kyphotic deformity in ankylosing spondylitis include preoperative determination of the required angle of wedge spine section. In s patient in vertical position the vertical segment is measured, plotted from the level of outer ear canal to the horizontal line drawn through the apex of ridge of wing of ilium and a distance from the external auditory canal to the point of intersection of the horizontal line above the ridge of ilium. In vertical, drawn through the trochanter with known sides of the right triangle, proximal angle is determined which is equal to the angle of body inclination corresponding to the angle of wedge section of the spine.
