Clinical Study

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

Figure 4

A 59-year-old male patient presented with severe back pain and progressive kyphotic deformity. Lateral radiograph (a) before surgery showed local kyphosis of 36° and pseudarthrosis at T10-T11 level. Immediately after surgery lateral X-ray (b) revealed transpseudarthrosis osteotomy and interbody fusion with PEEK cage (arrow). Three months after surgery, normal sagittal alignment was maintained and partial union (c, arrow) was obtained. At final follow-up, no evidence of nonunion and no loss of correction on lateral X-ray (d).
