This anatomic study described robotic approaches to the posterior thoracolumbar spine in a porcine model. Ergonomics, control, and approach and technical difficulties were noted. ⋯ The da Vinci could perform the major noninstrumented procedures of the posterior spine with improved ergonomics and control. Surgeon fatigue and tremor were reduced. With some modification of prototype and commercial instruments a posterior spine surgery instrument kit can be developed. Future clinical studies can better assess patient and surgeon benefits of using the da Vinci robot for posterior spine surgeries.

Comparative Study Clinical Trial
Comparative study of neck pain in relation to increase of cervical epidural pressure during percutaneous endoscopic lumbar discectomy.
A prospective study. ⋯ Neck pain occurring during PELD is associated with a highly increased cervical EP generated by continuous infusion.

Analysis of magnetic resonance (MR) images of healthy volunteers. ⋯ MR imaging was successfully implemented as a noninvasive method for visualizing the synovial folds of the lateral atlantoaxial joints and quantifying their dimensions in healthy volunteers. The results of this study provide a basis for future studies investigating synovial fold pathology in patients with neck pain and headache.

A unique case of a patient with diffuse idiopathic skeletal hyperostosis (DISH) associated with C1 posterior tubercle impingement resulting in spinal canal stenosis and cervical myelopathy. ⋯ This is the first report of unique C1 posterior tubercle impingement and myelopathy caused by DISH. We should keep it in mind that DISH can cause serious problems in the upper cervical spine even after 25 years of interval.
