In AIS, the abolition of T7-T10 dynamics related to the stiffness induced by the apex region in Lenke IA curves could harm ventilation during maximal breathing. The aim of this study was to analyze the dynamics of the thoracic spine during deep breathing in AIS patients and in healthy matched controls.

A series of 36 AIS immature patients (Risser 3 or less) were included in the study. Instrumentation was removed once the maturity stage was complete (Risser 5).

- The study focused on the effects of surgery for thoracic deformity on cardiorespiratory function in adolescents with moderate-severe Scheuermann's hyperkyphosis.
- A group of 23 patients underwent surgery, and key parameters like heart rate and maximum oxygen uptake were tested before and two years after the procedure.
- Although there were statistically significant improvements in some respiratory measures, the changes were not clinically significant, suggesting the improvements could be due to natural growth rather than the surgery itself.
Objective: To describe the accuracy of middle pedicle track stimulation for the detection of pedicle breaches causing misplaced lumbar screws and subsequent neurological symptoms.
Patients And Methods: In a comparative observational study with two cohorts, 1440 lumbar pedicle screws were implanted using the freehand technique in 242 patients undergoing surgery for spinal deformities. In the first two-year period (2011-2012), the accuracy of screw placement (802 screws) was assessed by conventional intraoperative palpation of the pedicle track, t-EMG screw stimulation, and fluoroscopic monitoring.
