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.

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.

Multicenter Study
Adding thoracic fusion levels in Lenke 5 curves: risks and benefits.
Multicenter; review of prospectively collected data. ⋯ Adolescent idiopathic scoliosis surgeons attempt to achieve balanced correction with the fewest motion segments fused. Our data suggest that fusion of the thoracic curve in primary thoracolumbar scoliosis may improve coronal correction, but at the cost of decreased thoracic kyphosis and clinical flexibility 2 years postoperatively.

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.
