The clinical relevance of the presence of bridging syndesmophytes on kyphosis correction and maintenance following pedicle subtraction osteotomy for thoracolumbar kyphotic deformity in ankylosing spondylitis: a comparative cohort study

The presence of bridging syndesmophytes (BS) in spinal osteotomy region serves traditionally as one critical determinant for selection of osteotomy techniques. While nowadays the proportion of kyphotic ankylos...

Abstract BACKGROUND: Andersson lesions (ALs), also known as spondylodiscities, destructive vertebral lesions and spinal pseudarthrosis, usually occur in patients with ankylosing spondylitis (AS). Inflammatory and traumatic causes have been proposed to define this lesion. Different surgical approaches including anterior, posterior, and combined anterior and posterior procedure have been used to address the complications, consisting of mechanical pain, kyphotic deformity, and neurologic deficits. However, the preferred surgical procedure remains controversial. The aim of this study was to illustrate the safety, effi...

This study was to investigate the role of pelvic incidence (PI) in the development of Andersson lesions (ALs) in ankylosing spondylitis (AS) patients with kyphosis and to evaluate the difference in sagittal spinopelvic parameters between inflammatory ALs and mechanical ALs.MethodA total of 135 AS patients with kyphosis were reviewed. The patients were classified into AL group and non-AL group based on the presence or absence of ALs. Additionally, AS patients with ALs were also classified as either inflammatory or mechanical lesions depending on the radiological features of the lesions. The sagittal spinopelvic parameters o...

Study Design. Retrospective study. Objective. To describe the treatment results of patients with severe ankylosing spondylitis (AS) kyphosis who underwent two-level osteotomy and correction surgery. Summary of Background Data. The best solution for the fixed kyphotic deformity of AS is corrective osteotomy. Many osteotomy options are available: pedicle subtraction osteotomy (PSO), Smith-Peterson osteotomy (SPO), and vertical column resection (VCR). These procedures all provide multiplanar deformity correction. Nevertheless, when the AS deformity is severe, an additional osteotomy site to get more correction, achiev...

Radiographic realignment objectives for the surgical correction of adult spinal deformity (ASD) has been well-described. However, the optimal sagittal spinopelvic alignment after corrective osteotomy for thoracolumbar kyphosis secondary to ankylosing spondylitis (AS) is still unknown so far.

Conclusion: To the authors' knowledge, this is the first report detailing a vest-like support apparatus for patients with thoracic kyphosis used in vitreoretinal surgery. This apparatus can be prepared using any conventional operating table, and it offers an effective approach to intraocular surgery for patients who cannot lie flat.

The head's center of gravity (COG) plumb line (PL) and C7 PL could be simultaneously positioned over the pelvis in adult spinal deformity (ASD) with normal cervical mobility. However, the position of the head in relation to the global spinal alignment has yet to be investigated in ankylosing spondylitis (AS) patients with thoracolumbar kyphosis.

Authors: Feng C, Tao H, Yang K, Xu J, Duan C, Yang W, Li H, Li H Abstract BACKGROUND The aim of this study was to analyze the clinical and radiological outcomes of modified closing-opening wedge osteotomy (mCOWO) for correcting kyphosis in ankylosing spondylitis (AS) patients. MATERIAL AND METHODS From April 2012 to April 2017, records of consecutive patients who underwent mCOWO were reviewed. The clinical and radiological outcomes were analyzed preoperatively, postoperatively, and at the most recent follow-up. RESULTS Eleven AS patients underwent mCOWO, with a mean follow-up of 19.4 months (range, 12-45 months). T...

Conclusion. This study demonstrated the psychological changes and subsequent improvement in employment outcomes after corrective osteotomy in patients with AS. The degree of sagittal alignment correction was correlated with improvements in psychological status and employment outcomes. Level of Evidence: 4
