Multicenter Study
Long Term Patient Perception Following Surgery for Adolescent Idiopathic Scoliosis if Dissatisfied at 2 Year Follow-up.
Longitudinal. ⋯ Having a low HRQOL score 2 years after surgery for AIS does not guarantee a low score 5 years after surgery. Promisingly, most patients demonstrate some improvement in all domains for patient-reported SRS-22 scores at 5-year compared to 2-year follow-up. Understanding the longer term postoperative evolution in patient-reported outcomes may help surgeons to effectively manage and counsel patients who are dissatisfied in the short term.Level of Evidence: 3.

An in-vitro biomechanical study of human cadaver sacroiliac joints. ⋯ A nontrivial amount of rotation and translation occurred out of the expected axis of motion. The largest amount of off-axis rotation was observed in lateral bending. Relative to resultant translation, in-plane translation was lowest in lateral bending. Our results indicate that rotation of the SIJ is not fully described with the in-plane metrics which are normally reported in evaluation of fusion devices. Future studies of the SIJ may need to consider including off-axis rotation measurements when describing SIJ kinematics.Level of Evidence: 5.

A cross-sectional analysis using T1 slope (T1S) and C7 slope (C7S) in asymptomatic individuals. ⋯ The normative values and age-related changes in C7S and T1S were analyzed. Both the C7S and T1S angles increased with age. The C7S angle was strongly correlated with the T1S angle, suggesting that C7S can substitute T1S on radiographic images.Level of Evidence: 3.

Observational Study
A Prospective Cohort Study of Dysphagia after Subaxial Cervical Spine Surgery.
Prospective observational cohort study. ⋯ Fusion surgery and increased CL after surgery were risk factors for development of dysphagia after subaxial cervical spine surgery. Cervical alignment change due to anterior and posterior fusion surgery can cause postoperative dysphagia.Level of Evidence: 3.

A retrospective study. ⋯ The incidence of distal AO was 23.1% in CMS patients after PSF. Patients with low Risser sign and LIV-LSTV ≤0 were high risk factors for distal AO.Level of Evidence: 3.
