Augmented reality (AR) is an emerging technology with great potential for surgical navigation through its ability to provide 3D holographic projection of otherwise hidden anatomical information. This pilot cadaver study investigated the feasibility and accuracy of one of the first holographic navigation techniques for lumbar pedicle screw placement. ⋯ This pilot study demonstrates improved angular precision in one of the first AR-navigated pedicle screw placement studies worldwide. Technical shortcomings need to be eliminated before potential clinical applications.

The presence vertebral artery (VA) abnormalities in the upper cervical may be a potential cause of catastrophic complication in the posterior approach of the upper cervical spine surgery. The aim of this study was to demonstrate the real incidence of the V3 segment anomaly in patients who need upper cervical surgery, and tried to find out the risk factors of V3 segment anomaly to evaluate the necessary of computed tomographic angiography (CTA) for upper cervical surgery. ⋯ Patients with bone abnormalities are high risk factor for VA abnormalities, CTA is of paramount importance to evaluate the variant VA anatomy. However, regarding to the low incidence of V3 variation in normal population, we do not recommend preoperative CT angiography as mandatory part of preoperative.

Review Meta Analysis
Comparison of interventions and outcomes of enhanced recovery after surgery: a systematic review and meta-analysis of 2456 adolescent idiopathic scoliosis cases.
The objective of this meta-analysis and systematic review is to compare the methodology and evaluate the efficacy of Enhanced recovery after Spine Surgery (ERAS) for adolescent idiopathic scoliosis (AIS) and to compare the outcomes with traditional discharge (TD) pathways. ⋯ Meta-analysis of Level 3 studies.

This study systematically analyzed and assessed the interrelationships among vertebral anomaly location, congenital scoliosis (CS) type and associated abnormality prevalence. ⋯ Cervical malformations had higher prevalence of mixed defects, musculoskeletal and intraspinal defects and multi-region involved. Thoracic malformations had higher prevalence of intraspinal and musculoskeletal defects and more involvement of only one vertebral region. Lumbar vertebral malformation patients had much lower prevalence of intraspinal and musculoskeletal defects and more involvement of only one vertebral region. Cervical malformation was a risk factor for more associated anomalies and more severe vertebral anomalies, which deserves more attention from surgeons in outpatient clinic.

In conservative early onset scoliosis treatment, interest in bracing is growing because repeated general anaesthesia (required by casting) has been questioned for possible brain damages. We aimed to check the results in the medium term of bracing, comparing idiopathic (IIS) to secondary (SIS) infantile scoliosis. ⋯ Bracing shows promising results in the medium term for high-degree IIS, with very few hold-ups (19%) and failures (12%). Conversely, failures prevail for SIS (full 11%), even if the partial failure (39%) is still a time-buying strategy.
