Transpseudarthrosis Osteotomy with Interbody Fusion for Kyphotic Spinal Pseudarthrosis in Ankylosing Spondylitis by a Single Posterior Approach: A Retrospective Study and a Brief Relevant Literature Review

<div>A 54-year-old female patient presented with painful round kyphosis and motor loss of bilateral lower extremities. CT scan showed destruction of the vertebral body and vacuum phenomenon (a, arrow). CT sagittal reconstruction image (b) demonstrated irregular bony gap (arrow) from anterior to posterior column and sclerosis of adjacent vertebral bodies. T2- (c) and T1-weighted (d) sagittal images revealed low signal at the pseudarthrosis and compression of the spinal cord.</div>
