A retrospective study of 24 sacroiliac joint computed tomographic (CT) scans of patients with persistent donor site pain. ⋯ There is a high prevalence of inner table disruption in patients with persistent sacroiliac joint pain after posterior iliac bone graft harvesting. The computed tomographic scan showed that involvement of the synovial part caused more severe degenerative changes than involvement of the ligamentous part.

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.

Comparative Study
Effects of core body temperature on changes in spinal somatosensory-evoked potential in acute spinal cord compression injury: an experimental study in the rat.
Acute spinal cord injury was induced by a clip compression model in rats to approximate spinal cord injury encountered in spinal surgery. Spinal somatosensory-evoked potential neuromonitoring was used to study the electrophysiologic change. ⋯ Systemic cooling may protect against the detrimental effects of aggressive spinal surgical procedures. There is still not enough published information available to establish statistically and ethically acceptable intraoperative neuromonitoring warning and intervention criteria conclusively. Therefore, an urgent need exists for further investigation. Although a reduction of more than 50% in evoked potential still seems acceptable as an indicator of impending neural function loss, maintenance of more than 50% of baseline evoked potential is no guarantee of normal postoperative neural function, especially at lower than normal temperatures.

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.

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.
