INTRODUCTION: Recent developments of spinal instruments allow to address nearly all components of idiopathic scoliosis. Direct vertebral rotation (DVR) maneuver was introduced to correct apical axial vertebral rotation. It is however still not well established how efficiently DVR affects results of scoliosis correction. The object of the study was to evaluate en bloc apical vertebral rotation (DVR) and its impact on coronal and sagittal correction of the spine in patients undergoing surgical scoliosis treatment...

Superior mesenteric artery (SMA) syndrome is a rare and potentially life-threatening complication of scoliosis surgery. The anatomical relationship of the duodenum and the superior mesenteric artery, the correction of angular deformity of the spine, and the normal adolescent growth spurt all contribute to the condition. We report the case of a 14-year-old boy who had a history of idiopathic scoliosis and presented with bilious vomiting that had persisted for 7 days after posterior T9-L4 fusion with instrumentation...

BACKGROUND: Adjacent segment disease (ASD) is a common complication after lumbar decompression and fusion surgery. Traditional revision-surgery, including posterior lumbar decompression and posterolateral fusion (PLF) or interbody fusion (PLIF) is traumatic. The percutaneous endoscopic transforaminal procedure (PE-TF) has been widely used in patients with lumbar disc disease. However, there are no reports about using PE-TF procedure to treat ASD in the current literature. OBJECTIVE: To compare the clinical outcomes between PE-TF and PLF for single-level ASD after PLF or PLIF...
