The aim of this study was to report the clinical and radiographic outcomes of 21 patients with severe thoracic kyphosis who underwent surgical correction by pedicle subtraction osteotomy. A retrospective multicentric study was conducted among a sample of patients who underwent single-stage correction via a posterior surgical approach. Pedicle subtraction osteotomy (PSO) was performed in all patients who presented a kyphotic deformity exceeding 70°. The cohort included 5 males and 16 females, with an average age of 62.7 years at the time of surgery. The minimum follow-up was 36 months, and the mean follow-up was 39.3 months. Following surgery, kyphosis across the treated segments was reduced by an average of 26.5°. Both back pain and neurological function improved after surgical treatment. There was a 68.2% improvement in VAS scores. Severe thoracic kyphosis can be improved through corrective surgery, and deformity correction can be accompanied by improvement in clinical symptoms.
