Risser stage is widely used as a marker for skeletal maturity (SM) and thereby an indirect measure for the risk of progression of adolescent idiopathic scoliosis (AIS). The Scoliosis Research Society recommends bracing for Risser stages 0-2 as Risser stage 3 or above is considered low risk. Very few studies have assessed the risk of progression during bracing in Risser stages 3-4. The objective of the current study is to determine if Risser stages 3-4 provide a meaningful cutoff in terms of progression risk in patients with AIS treated with night-time bracing. ⋯ Risser stage does not provide a clinically meaningful differentiation of progression risk in AIS patients treated with a night-time brace. Risk assessment should include other more reliable measures of skeletal growth potential.

Previous studies on the natural history of moderate to severe idiopathic scoliosis show contradictory results. Some studies reported an increased incidence of back pain and disability in severe curves, while other studies reported no difference in health-related quality of life (HRQoL) compared to age-matched adult controls. None of these studies addressed HRQoL using currently recommended and validated questionnaires. ⋯ Patients with idiopathic scoliosis and curves of 45° or higher have reduced HRQoL. Although many patients experience back pain, the disability reported on the ODI was limited. Scoliosis had noteworthy effect on choice of education.

To summarize the mechanical loading of the spine in different activities of daily living and sports. ⋯ These results may help to identify acute and long-term risks of low back pain and, thus, may guide the development of preventive interventions for low back pain or injury in athletes.

To compare the safety and accuracy of cannulated pedicle screw placement using a robotic-navigation technique, O-arm-based navigation technique, or freehand technique. ⋯ The robotic-navigation and O-arm-based navigation techniques effectively increased the accuracy and safety of pedicle screw insertion alternative to the freehand technique in scoliosis surgery. Compared with the O-arm-based navigation technique, the robotic-navigation technique increases the mean operation time, but also increases the accuracy of pedicle screw placement. A three-dimensional scan after insertion of the K-wire may increase the accuracy of pedicle screw placement in the O-arm-based navigation technique.

This study aimed to investigate the changes of the posterior paraspinal muscles (PPM) and psoas muscle in patients with low back pain (LBP) over time. ⋯ The study revealed significant quantitatively muscular changes in males and females, especially in the posterior paraspinal muscles in only three years' time.
