Randomized Controlled Trial
Prone versus knee-chest position for microdiscectomy: a prospective randomized study of intra-abdominal pressure and intraoperative bleeding.
Prospective randomized study. ⋯ Intra-abdominal pressure did not differ between prone position on a modified Relton-Hall frame and knee-chest position on an Andrew-type table. Both positions provide good conditions for lumbar microdiscectomy.

Comparative Study
Intervertebral motion after incremental damage to the posterior structures of the cervical spine.
Compare intervertebral motion after incremental damage to posterior cervical structures in whole cadavers to motion in asymptomatic subjects. ⋯ Radiographic assessment of the cervical spine may not be sufficient to exclude even extensive damage to the posterior structures of the cervical spine.

Prospective longitudinal study of patients attending a back pain triage clinic with night pain. ⋯ Although it is a significant and disruptive symptom for patients, these results challenge the specificity of the presence of night pain per se as a useful diagnostic indicator for serious spinal pathology in a back pain triage clinic.

The authors provide their results in performing multilevel oblique corpectomy for degenerative spondylotic myelopathy in 48 patients. ⋯ Multilevel oblique corpectomy was found to be a safe technique that guarantees good results in terms of both regression of clinical symptoms and long-term spinal stability.

An in vivo rat model of transient cervical nerve root compression. ⋯ Results imply a force threshold exists less than 10 gf for persistent pain symptoms following transient cervical nerve root compression. Findings also suggest that spinal glial activation may be related to behavioral sensitivity and may modulate cervical nerve root mediated pain.
