Abstract
In deformity surgery in adults, pseudarthrosis remains an important cause of progressive deformity and postoperative pain. Revision surgery for pseudarthrosis in the lumbar spine is a difficult challenge with failure rates of as much as 50% using posterior surgery alone. Treatment of pseudarthrosis of the thoracic spine has not been well-described. The purpose of the current study was to review the long-term clinical and radiographic results of posterior-only surgery for the treatment of pseudarthrosis in the thoracic spine. Using a posterior extension osteotomy through the identified pseudarthrosis with reinstrumentation and autogenous bone grafting, an improvement of regional sagittal balance was shown and reliable clinical outcomes were obtained. A single-stage posterior revision surgery with extension osteotomies through the regions of pseudarthrosis coupled with rigid internal fixation and autogenous bone grafting is an effective technique for treatment of pseudarthrosis of the thoracic spine. This technique improves regional sagittal deformity and leads to reliable arthrodesis. Combined anterior and posterior surgery was not necessary for effective treatment of thoracic pseudarthrosis in this series.
