A prospective study. ⋯ The outcomes of this minimally invasive fusionless technique at 5 years follow-up showed a stable correction of spinal deformities and pelvic obliquity over time, with a reduced rate of complication. The arthrodesis was not required for all patients at skeletal maturity. This technique could be a good alternative to arthrodesis for neuromuscular scoliosis.Level of Evidence: 3.

Observational Study
Construct Validity and Item Response Theory Analysis of the PROMIS-29 v2.0 in Recipients of Lumbar Spine Surgery.
Observational cohort design involving measurement property assessment. ⋯ The PROMIS-29 v2.0 measures several different constructs pertinent to a patient's health and recovery during spine surgery. We feel that the PROMIS-29 v2.0 tool is a useful and effective outcome measure for populations who receive spine surgery.Level of Evidence: 4.

A cervical biomechanical study. ⋯ CBCT combined with 3D-3D registration was used to accurately measure and record the ROMs of lateral bending, axial rotation, and flexion-extension in cervical vertebrae under physiological-load conditions. Our findings may contribute to the diagnosis of cervical spinal disease, the development of new surgical techniques, and the restoration of normal, cervical segmental movement.Level of Evidence: 3.

A cross-sectional study. ⋯ The thecal sac area was reduced in older age group from T12/L1 to L4/5, and the thecal sac area was reduced in the anteroposterior and all directions in the upper and lower lumbar area in age group, respectively. Approximately, 3.0% of healthy population in their 50s or older will have severe asymptomatic stenosis.Level of Evidence: 2.
