Analyze the modifications in the "safe zones" of T4-L4 vertebral bodies relative to aorta according to patient positioning, as well as in the relationship between the aorta and the vertebrae. ⋯ Patient positioning during spinal surgery significantly modifies T4-L4 vertebral safe zones relative to aorta. These variations should be taken into account when analyzing an MRI performed in supine if the patient is undergoing surgery in a different position, to avoid vascular-related injuries.

To assess the comparative accuracy of commonly utilised index radiological measurements in the prognosis of infantile idiopathic scoliosis (IIS) and build a parsimonious prognostic model utilising these measurements. ⋯ Of the three analysed index radiological parameters commonly used by surgeons in the prognosis of IIS, we found that the Cobb angle is the most accurate predictive measure. Further, neither addition of the RVAD nor convex RVA provided significant further prognostic value in a multivariate model of progression. However, not even the Cobb angle model was accurate in all cases; emphasising caution should be applied when relying on index radiological measurements to predict IIS outcomes.

Four-rod instrumentation and interbody fusion may reduce mechanical complications in degenerative scoliosis surgery compared to 2-rod instrumentation. The purpose was to compare clinical results, sagittal alignment and mechanical complications with both techniques. ⋯ III.

Review Meta Analysis
Surgical outcomes following hemivertebrectomy in congenital scoliosis: a systematic review and observational meta-analysis.
Hemivertebrectomy is widely used definitive correction surgery in congenital scoliosis due to hemivertebrae. It may be done either as combined anterior and posterior approach or a single-stage posterior approach only. The purpose of this meta-analysis was to compare two techniques with regards to blood loss, operative time, deformity correction and complications. ⋯ IV.

Review Meta Analysis
The role of TaqI, ApaI and BsmI polymorphisms of VDR gene in lumbar spine pathologies: systematic review and meta-analysis.
The objective of the present meta-analysis was to evaluate the association between TaqI (rs731236), ApaI (rs7975232) and BsmI (rs1544410) polymorphisms of the VDR gene and lumbar spine pathologies such as lumbar disc herniation and lumbar disc degeneration. ⋯ Our findings indicate that TaqI and ApaI polymorphisms of the VDR gene are important risk factors for developing lumbar spine pathologies. Moreover, the TaqI polymorphism is a risk factor for lumbar disc degeneration.
