The study design is a retrospective review of consecutive case series. Our goal was to identify and quantify the effect of skeletal traction on the apical vertebral rotation (AVR). Intra-operative skeletal traction has been used for the correction of large magnitude idiopathic and neuromuscular scoliosis. ⋯ The minor structural curve corrected from a mean Cobb of 53.5 degrees to 33.8 degrees (37.8%) with AVR decreasing from a mean of 1.9 to 1.4 (p = 0.014). Significant apical derotation occurs with the use of intra-operative skull-skeletal traction in the correction of high magnitude scoliotic curves. This derotation can facilitate spinal exposure, placement of pedicles screws and final correction in these patients.
