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.

Prospective clinical study of intraoperative transcranial motor-evoked potentials (TcMEP) amplitudes and postoperative motor deficits. ⋯ We determined the cutoff amplitude for predicting postoperative motor deficits in thoracic spine surgery. The results may help establish the alarm criteria for thoracic spine surgery.

Biomechanical tensile testing of perinatal, neonatal, and pediatric cadaveric cervical spines to failure. ⋯ Cervical spine tensile stiffness-to-failure and load-to-failure increased nonlinearly, whereas normalized displacement at failure decreased nonlinearly, from birth to adulthood. Pronounced ligamentous laxity observed at younger ages in the O-C2 segment quantitatively supports the prevalence of spinal cord injury without radiographic abnormality in the pediatric population. This study provides important and previously unavailable data for validating pediatric cervical spine models, for evaluating current scaling techniques and animal surrogate models, and for the development of more biofidelic pediatric crash test dummies.

Retrospective study. ⋯ APSF with FSAG for dystrophic deformity in NF-1 successfully reconstructed a reliable spinal column with a rich bone stock. The FSAG and surrounding vertebral bodies were free from postoperative erosion due to dystrophic changes and maintained their stability for a long time.

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.
