In addition to changes in the skeletal system after spinal osteotomy for treatment of kyphotic deformity in advanced-stage AS patients, many other systemic changes associated with the patients' quality of life were reported. The purpose of this study was to conduct a systemic review of the literature to determine systemic changes associated with patients' quality of life following correction of kyphotic deformity secondary to ankylosing spondylitis. ⋯ In addition to skeletal changes after spinal osteotomy for treatment of kyphotic deformity in advanced-stage AS patients, many other changes were reported. Spine surgeons should pay more attention to these life quality-related changes and be aware of potential risks when performing surgery for advanced-stage AS patients.

Multicenter Study Observational Study
Preoperative SRS pain score is the primary predictor of postoperative pain after surgery for adolescent idiopathic scoliosis: an observational retrospective study of pain outcomes from a registry of 1744 patients with a mean follow-up of 3.4 years.
Traditionally, adolescent idiopathic scoliosis (AIS) has not been associated with back pain, but the increasing literature has linked varying factors between pain and AIS and suggested that it is likely underreported. ⋯ 12% of all AIS patients who underwent fusion had back pain after postoperative recovery. The most consistent predictive factor of increased postoperative pain across all curve types was a low preoperative SRS pain score.

Clinical ultrasound is radiation-free, low cost and user friendly, which makes it probable in assessment of scoliosis. Numerous studies have been conducted about the feasibility of using clinical ultrasound to assess scoliosis; thus, an inclusive review of the literature would be beneficial for researchers, clinicians and patients. This study aimed to systematically review the reliability and validity of coronal curvature assessments obtained from different clinical ultrasound imaging methods. ⋯ A high level of evidence was found in support of the reliability and validity of the COL (centre of lamina) ultrasound method. Further reliability and validity studies should be conducted to strengthen the level of evidence for those ultrasound methods with moderate, limited or conflicting level of evidence.

The purpose of the present study was to validate a new spinal sagittal classification. ⋯ The distribution of the four sagittal patterns varies between AIS cohorts. Type 2b was rare, which limits the clinical applicability. Contrary to the original publication, we found that the spinopelvic parameters lumbar lordosis, pelvic incidence and sacral slope were significantly different between the Abelin-Genevois types. Hence, the corrective surgical strategy may need to incorporate these spinopelvic parameters to achieve a balanced spine requiring a minimum of energy expenditure.
