To analyze the compression of the dural sac and the cervical spinal movement during performing different airway interventions in case of atlanto-occipital dislocation. ⋯ In case of atlanto-occipital dislocation, intubation using direct laryngoscopy exacerbates dural sac compression and may cause damage to the spinal cord.

The aim of the study was to evaluate the efficacy and safety of the direct lateral approach to the lumbar spine in the treatment of painful isthmic spondylolisthesis in adults. ⋯ The study showed that the extreme lateral approach to the lumbar spine in case of isthmic spondylolisthesis is a reliable and safe option to the most common open procedures. In the authors' opinion, XLIF procedures allow a good correction of the listhesis associated with good clinical and radiographic results.

Aim of this study was to investigate the effectiveness of a new surgical corrective manoeuvre for adolescent idiopathic scoliosis (AIS) by asymmetrically shaped and simultaneously applied rods and in combination with direct vertebral rotation, to control both the triplanar deformity and the kyphosis apex location. ⋯ The corrective manoeuvre using two differently contoured rods simultaneously in combination with direct vertebral rotation can provide a good triplanar deformity correction and improve patient's quality of life and self-image perception in mild-to-moderate AIS. Moreover, the described technique allows the positioning of the desired kyphosis apex at a different level from the scoliosis apex. This procedure allows a better sagittal contour restoration while maintaining a comparable amount of correction on the frontal and axial plane of the already available techniques. These slides can be retrieved under Electronic Supplementary Material.

Hirayama disease is an initially progressive disease caused by cervical neck flexion compressing the anterior horns of the lower cervical spinal cord. It is primarily seen in young males of Indian or Asian descent. With increasing dispersion of these populations this condition is increasingly being encountered internationally. This grand round reviews this rare but increasingly recognized condition. ⋯ This case illustrates the typical presentation, diagnostic investigations and treatment of Hirayama syndrome. It is hoped that this review will alert clinicians of this condition and optimize the management of affected individuals.

To determine the prevalence, radiographic features and reporting rate of, and the association between the congenital anterior and posterior C1 arch anomalies. ⋯ Although some types of congenital C1 arch anomalies are rare, type A defects are relatively common radiological findings that are unreported approximately 45% of the time. Based on the significant association between the anterior and posterior arch defects, we propose possible mechanisms for the formation of the bipartite atlas.
