Clinical Trial
Providence nighttime bracing is effective in treatment for adolescent idiopathic scoliosis even in curves larger than 35°.
Since 2006, the Providence nighttime brace has been used for a conservative treatment for scoliosis. Previous studies comparing the outcomes after full-time bracing and nighttime bracing have reported a comparable outcome with curves < 35°. The aim of this study was to report the outcome after treatment in a cohort of adolescent idiopathic scoliosis patients, with curves between 20° and 45°.

To clarify the relationship between sarcopenia and spinopelvic parameters. ⋯ Sarcopenia is related to spinal sagittal imbalance because of insufficient compensation by flattening thoracic kyphosis in patients with spinopelvic mismatch.

To evaluate the outcome of degenerative lumbar spine surgery in a credible way, patient-reported outcome measures (PROMs) should be assessed after an adequate follow-up period. Most authors/journals consider a follow-up period of less than two years to be too short. The purpose of this study was to explore the possibility of restricting follow-up to one year. ⋯ For all the three diagnostic groups, the differences in proportions reaching MIC of each PROM at 1 and 2 years were below 2%. Global Assessment and Satisfaction with outcome at one year remained at 2 years. There were no important differences of threshold values of treatment success based on final scores CONCLUSION: No clinically important changes in PROMs appeared between 1 and 2 years after surgery for degenerative lumbar conditions, demonstrating that a follow-up period of 1 year as opposed to 2 years is sufficient in effectiveness studies if PROMs are to be used as outcome variables.

Observational Study
Criteria for surgical reduction in high-grade lumbosacral spondylolisthesis based on quality of life measures.
Although surgical reduction in high-grade lumbosacral spondylolisthesis is often performed in young patients, criteria for defining adequate reduction leading to optimal outcomes have yet to be defined. The purpose of this study is to determine if surgical reduction in pelvic balance, slip grade, lumbosacral angle and L5 incidence are associated with quality of life after surgery, based on specific criteria proposed previously in the literature. ⋯ When performing surgery in young patients with high-grade lumbosacral spondylolisthesis, achieving normal pelvic balance is the key because it is associated with improved quality of life. Reduction to a low-grade slip is predictive of improved mental health, but reduction in lumbosacral angle is not associated with postoperative quality of life. There was a tendency for obtaining normal postoperative balance in patients with postoperative L5 incidence 60° or smaller. These slides can be retrieved under Electronic Supplementary Material.
