Spine
-
Experimental design. ⋯ Pain reduction after facet joint injections did not influence isokinetic muscle performance in patients with degenerative low back disorders.
-
Introduction of a posterior approach for internal fixation of fractures of the ankylosed cervical spine. ⋯ Patients with ankylosing spondylitis and cervical spinal fractures can be adequately treated with lateral mass plating and interspinous wiring of autologous rib graft. Adequate postoperative immobilization can be attained with a cervical collar and does not require a halo vest.

Randomized Controlled Trial Clinical Trial
Does early intervention with a light mobilization program reduce long-term sick leave for low back pain?
A controlled randomized clinical trial was performed. ⋯ Early intervention with examination, information, and recommendations to stay active showed significant effects in reducing sick leave for patients with low back pain.

Comparative Study
Segmental stability and compressive strength of posterior lumbar interbody fusion implants.
Human cadaveric study on initial segmental stability and compressive strength of posterior lumbar interbody fusion implants. ⋯ The biomechanical data did not suggest any implant construct to behave superiorly either as a stand-alone or with supplemental posterior fixation. The PLIF Allograph Spacer is biomechanically equivalent to titanium cages but is devoid of the deficiencies associated with other cage technologies. Therefore, the PLIF Allograft Spacer is a valid alternative to conventional cages.

Review Case Reports
Idiopathic spinal cord herniation: report of three cases and review of the literature.
Three case reports and a literature review are presented. ⋯ Because idiopathic spinal cord herniation is out of the concept of "compression myelopathy," this condition may be a pitfall in the diagnosis. Idiopathic spinal cord herniation should be recognized as one of the treatable causes for thoracic myelopathy.
