Biomechanical analysis of vertebral derotation techniques for the surgical correction of thoracic scoliosis. ⋯ Biomechanically, it is possible to significantly improve the correction of thoracic scoliotic deformities, particularly in the transverse plane, when using vertebral derotation maneuvers.
-
Prospective patient series. ⋯ Thoracic elongation improved pulmonary function, facilitated weight gain, and made an indirect correction of spinal deformities (Cobb angle) by more than 30%, with no significant complications. Because of the rarity of this condition, a multicenter study to gain experience in a larger number of patients is recommended.

Retrospective. ⋯ IOM data identified 386 (3.1%) patients with loss/degradation of data in 12,375 spinal surgical procedures. Fortunately, in 93.3% of patients, intervention led to data recovery and no neurological deficits. Reduction from a potential (worst-case scenario) 3.1% (386) of patients with significant change/loss of IOM data to a permanent neurological deficit rate of 0.12% (15) patients was achieved (P < 0.0001), thus confirming efficacy of IOM.

Retrospective cohort study. ⋯ Mortality predictors for spine trauma patients are similar to those for general trauma patients. Spine injury variables were shown not to be independent predictors of spine trauma mortality.

A biomechanical study of facet joint pressure after total disc replacement using cadaveric human cervical spines during lateral bending and axial torsion. ⋯ Implantation of a ProDisc-C does not significantly modify the kinematics and facet pressure at the index level in cadaveric specimens during lateral bending and axial torsion. However, changes in facet contact pressures after disc arthroplasty may have long-term effects on spinal loading and cartilage degeneration and should be monitored in vivo.
