Multicenter Study Comparative Study
Single- versus dual-rod anterior instrumentation of thoracolumbar curves in adolescent idiopathic scoliosis.
Single or dual-rod instrumentation can be used for the anterior fixation of the spine in adolescent idiopathic scoliosis (AIS). We aim to compare the complications, radiographic and functional outcomes of patients with AIS who have undergone single and dual-rod instrumentation. ⋯ Level III.

The choice of distal fusion level in adolescent idiopathic scoliosis (AIS) patients with major thoracolumbar or lumbar (TL/L) curves (Lenke type 3C, 5C, or 6C) remains debatable. One of the most controversial issues involves stopping the distal fusion at L3, which might result in an increased risk of decompensation but save more mobile spinal segments. The purpose of this study was to evaluate and compare the clinical and radiological outcomes of corrective surgery for AIS with major TL/L curves according to the distal fusion level. ⋯ There is no difference in the radiological and clinical outcomes in AIS according to the distal fusion level. Major TL/L curve correction in AIS may be sufficient distally at L3 in cases with an LEV ≥ L3 and LTV ≥ L4. However, stopping fusion at L3 requires caution in LEV ≤ L4 or LTV = L5 patients, as this correction rate might be suboptimal and causes a possible progression of the adjacent disc wedge angle.

To investigate the predictive role of rib-vertebral angle (RVA) measurements in early adolescent idiopathic scoliosis (AIS) girls with right thoracic curve during brace treatment. ⋯ The initial RVAD ≥20° and CRVA ≤68° serve as valid factors in predicting the risk of curve progression during bracing in early AIS. Constant watch on RVAD and CRVA can help to more accurately predict the effectiveness of bracing in these patients.

Clinical Trial
Assessment of sensorimotor control in adults with surgical correction for idiopathic scoliosis.
This study aims at verifying if impaired sensorimotor control observed in adolescents and young adults with scoliosis is also present in adult patients who underwent surgery to reduce their spine deformation. ⋯ This result suggests that dysfunctional sensorimotor integration is still present even in adult idiopathic scoliosis that underwent spine deformation correction.

Somatosensory evoked potentials (SSEPs) are effective in detecting upper extremity positional injuries; however, causal factors for which patient population is most at risk are not well established. ⋯ Sex, patient positioning, length of procedure, and BMI are determinants for upper extremity neural compromise during thoracolumbar and lumbosacral spine surgeries.
