The purpose of this study was to evaluate the effects of noise-optimised virtual monoenergetic imaging (VMI+) reconstructions on reducing metal artefacts compared to traditional virtual monoenergetic imaging (VMI) and linearly blended (M_0.6) reconstructions in patients with lumbar metal internal fixation in dual-energy CT (DECT). ⋯ DECT with high-keV VMI+ efficiently reduces metal artefacts and shows superior image quality in patients with lumbar internal fixation.

Whiplash injury (WI) represents a common diagnosis at every emergency department. Several investigations have been conducted to compare the different medical managements for non-surgical cases. However, the role of the immobilization with a non-rigid cervical collar (nRCC) for pain management and range of motion (RoM) preservation has not been completely clarified. ⋯ This pooled analysis of the available RCTs shows the absence of an advantage of the immobilization protocol with a nRCC after a WI. On the contrary, non-immobilization protocols show an overall better trend of pain relief and neck mobility recovery, regardless of the association of PhT.

The aim of this study is to present a unique case of a patient who presented to our Emergency Department with evidence of a chronic traumatic spondylolisthesis of the axis with severe displacement treated with anterior cervical discectomy and fusion (ACDF) of C2-C3 as well as and posterior cervical fusion (PCF) of C1-C3. ⋯ In this report, we present an alcoholic patient with a history of many falls who presented with a Levine type II traumatic spondylolisthesis of the axis with signs of chronicity seen on magnetic resonance imaging (MRI). We were able to partially reduce the anterior displacement with traction, but needed both anterior and posterior cervical approaches to achieve adequate reduction and stabilization of the injury.

Comparative Study
Analysis of a customized cervical collar to improve neck posture during smartphone usage: a comparative study in healthy subjects.
A slouching posture during smartphone usage increases gravitational loadings on the cervical spine, which may lead to neck pain and degeneration. The objective of the present study was to investigate the head, neck and trunk angles in different smartphone-usage postures, as well as the posture-correction effects and comfort scores of three neck collars. ⋯ Smartphone use increased both the head and neck flexion in different postures, and the proposed customized 3D-printed cervical collar significantly reduced the head and neck angles.

To present a novel technique for anterior instrumentation and reconstruction with PVCR for treatment of severe neglected congenital kyphosis through posterior approach. ⋯ Addition of anterior instrumentation to PVCR allows controlled gradual correction and more biomechanical stability. This technique should be preserved for high degrees of sagittal plane deformities. These slides can be retrieved under Electronic Supplementary Material.
