To compare the positions of the aorta relative to vertebral bodies and the potential risk of the aorta impingement for pedicle screw (PS) placement between right-sided and left-sided thoracolumbar/lumbar curves of adolescent idiopathic scoliosis (AIS). ⋯ The present study illustrated different changed positions of the aorta relative to vertebrae between thoracolumbar/lumbar curves with different convexities. In right-sided curve, the risks of the aorta impingement were mainly from left PS while in left-sided curves, from right PS. The aorta was more proximal to entry points in right-sided lumbar curve when compared with left-sided curve; thus placing PS carries more risks in right-sided thoracolumbar/lumbar curve. Surgeons should be more cautious when placing PSs on the concave sides of T12 and L1 vertebrae of right-sided thoracolumbar/lumbar curves.

Antidepressant medications are widely used by patients requiring spinal surgery. In spite of a generally favorable safety profile of newer antidepressants, several prior studies have suggested an association between use of serotonergic antidepressants and excessive bleeding. This study was designed to determine if there was any association between antidepressant use and the risk of excessive intraoperative blood loss during spinal surgery, and whether particular types of antidepressants were specifically associated with this increased blood loss. ⋯ Clinicians treating patients who are planning to undergo elective spinal surgery and are on an antidepressant medication should be aware of this potential effect and should consider tapering off the serotonergic antidepressant prior to surgery.

No information exists on the level of internet use among parents of pediatric patients with scoliosis. The internet may represent a medium through which to provide information to augment the outpatient consultation. The aim of this research was to establish the prevalence of internet use amongst a cohort of parents attending a pediatric scoliosis outpatient clinic. ⋯ As surgeons we need to be aware of our patients' use of the internet, and there is the opportunity to use this medium to provide additional education.

Persistent lower back pain after instrumental posterolateral desis may arise from incomplete fusion. We investigate the impact of experience on interobserver agreement in fusion estimation. ⋯ Difference in observer experience seems of minor impact.

Patients with adolescent idiopathic scoliosis (AIS) often present with a disfiguring shoulder imbalance. Shoulder balance (Sh.B) is of significant importance to the patient's self-perception. Previous studies have correlated Sh.B with respect to only the clinical posterior view correlated with radiographs. It is important, however, to address Sh.B with respect to anterior view of the patients' shoulders as if patients were viewing in a mirror. In this study, we evaluated the anterior Sh.B and correlated it with posterior Sh.B clinically and radiographically in Lenke type 1 and 2 curves. ⋯ There is no strong correlation between anterior and posterior clinical Sh.B, and surgeons should evaluate both sides in planning deformity correction, especially in Lenke 2 curves. None of the radiographic measures showed strong correlation (R > 0.8) with anterior or posterior clinical Sh.B. A stronger correlation existed between radiographic measures and anterior Sh.B measurements compared with posterior clinical Sh.B measurements in Lenke 2 curves further necessitating anterior evaluation in this group.
