Longitudinal cohort. ⋯ In this cohort of patients, using the single-index SF-6D produces a loss of discriminative properties compared with the SF-36 and ODI. However, this loss is small, because all the effect sizes remain large (≥0.80). Therefore, these losses should not preclude the use of the SF-6D compared with the SF-36 and may be preferred because it is more easily interpretable and less difficult to incorporate in economic evaluations.

A cross-sectional survey of spine surgery fellowship educators and trainees. ⋯ Background specialty influenced the perceptions of both fellowship educators and trainees. This study identified potential gaps or perceived deficiencies in the competency of current fellows. Improvements in spine fellowship education should target these areas through developing evidence-based curriculum changes.

Prospective case series study. ⋯ Percutaneous thoracoplasty-only procedure gives significant rib humps correction and satisfactory clinical outcome. However, progression of the curve was observed after surgery. This suggests that the convex ribs function as a buttress for curve progression.

This is a clinical case report with a review of relevant literature. ⋯ Patients with spondyloptosis of the cervical spine can rarely present with chronic neck pain and minimal neurological deficits. An additional pathology, such as atlantoaxial dislocation, can add to the complexity. Circumferential stabilization and fusion would be required in such cases to achieve a good outcome. Larsen syndrome is a rare cause of nontraumatic cervical displacements.
