To evaluate the global alignment of non-operated subjects with adolescent idiopathic scoliosis. ⋯ This study showed that frontal malalignment is more common in distal major structural scoliosis and its main driver is the apical vertebral rotation. This highlights the importance of monitoring the axial plane deformity in order to avoid worsening of the frontal global alignment.

To determine the midterm outcome of lateral thoracotomy (LT) in skeletally immature patients concerning thoracogenic scoliosis development and lung parenchyma resection (LPR) extent. ⋯ Although post-thoracotomy scoliosis is not associated with significant rotation, the risk of curve progression > 45° is relatively high. Regular follow-up is required as scoliosis may develop several years after LT with or without LPR.

Prone transpsoas fusion (PTP) is a minimally invasive technique that maximizes the benefit of lateral access interbody surgery and the prone positioning for surgically significant adjacent segment disease. The authors describe the feasibility, reproducibility and radiographic efficacy of PTP when performed for cases of lumbar ASD. ⋯ Single-position prone transpsoas lumbar interbody fusion is a clinically reproducible minimally invasive technique that can effectively treat lumbar adjacent segment disease.

To validate the authors kyphosis correction formula for pedicle subtraction osteotomy (PSO) cases. Additionally, to use the formula to evaluate the safety of PSO by determining if there is anterior lengthening. ⋯ This study validated the geometric and rough approximations originally used in PVCR patients, for PSO patients. Additionally, this study found that anterior lengthening may occur in PSOs usually at the discs, but occasionally at the osteotomized body.
