Cervical dumbbell tumor is usually removed via a posterior approach and may require the spinal fixation sometimes. However, the present surgical methods involved either more trauma or a higher risk of instability of the cervical spine. A new technique of unilateral exposure and stability reconstruction with pedicle and lamina screws fixation for posterior cervical dumbbell tumorectomy was described and compared with conventional techniques. ⋯ Diagnostic: individual cross-sectional studies with consistently applied reference standard and blinding.

The aim of the current study was to investigate the extent of smartphone use, possible correlation with neck pain and/or psychological impairment in office workers. ⋯ Smartphone overuse in office workers significantly increases the chance of neck pain by 6 times. Hence SO has been associated with, not only somatic complaints, but also psychological distress such as anxiety, stress, and depression. This may necessitate adherence to neck-school, when smartphone use is associated with neck pain.

Case Reports
Permanent twelfth nerve palsy secondary to C0 and C1 fracture in patient with craniocervical pneumatisation.
Craniocervical pneumatisation of both occiput and upper cervical vertebrae is extremely rare. Although it was stated that hyperpneumatisation can lead to fracture, only few cases of such injuries have been reported. Generally, craniocervical fractures represent a small number of cervical spine injuries and they are usually caused by high-energy trauma and can be associated with lower cranial nerves palsy. ⋯ At follow-up, the patient reported no pain and no restriction in head movement. Total hypoglossal nerve palsy remained unchanged. Conservative treatment is a method of choice in such cases.

In the context of regenerative medicine strategies, based in particular on the injection of regenerative cells, biological factors, or biomaterials into the nucleus pulposus (NP), two main routes are used: the transpedicular approach (TPA) and the transannular approach (TAA). The purpose of our study was to compare the long-term consequences of the TPA and the TAA on intervertebral disc (IVD) health through a longitudinal follow-up in an ovine model. ⋯ The TPA induced more severe lesions in IVDs and vertebrae compared to the TAA. The lesions induced by the TPA are reason to consider whether or not this route is optimal for studying IVD regenerative medicine approaches.
