Treatment of kyphotic deformity in ankylosing spondylitis.

This article reviews the available literature on the surgical options for the correction of kyphosis in ankylosing spondylitis and presents the radiologic appearance of the post-operative spine. In the postsurgical evaluation of the spine, the focus is on appreciation of the patterns of correction, early and late determination of angular correction, recognition of various complications (infection, nonunion, improper location, or breakage of hardware), and alertness to the possibility of complications at all levels of the spine.
