An in vitro biomechanical comparison of anteriorly placed lumbar plates, pedicle screws, and translaminar screws in the anterior lumbar interbody fusion (ALIF) setting. ⋯ Although not as rigid as pedicle or translaminar screws, anterior lumbar plating does add significant stability to an ALIF and may provide a valuable, single-approach alternative to supplemental posterior fixation.

Case Reports
Cord monitoring changes and segmental vessel ligation in the "at risk" cord during anterior spinal deformity surgery.
Retrospective analysis of all cases of anterior spinal deformity surgery that had intraoperative spinal cord monitoring (somatosensory-evoked potentials, SSEPs). ⋯ Patients with identified cords at risk should undergo spinal cord monitoring (SSEP) if they undergo anterior spinal deformity surgery. Soft clamping of segmental vessels is indicated with cord monitoring to prevent the risk of postoperative neurological sequelae.

The study used a small animal laminectomy model with kaolin to investigate the relationship of cauda equina pathology to pain, and the effects of systemic and intrathecal drugs to reduce pain. ⋯ An animal model of adhesive lumbar arachnoiditis yields a quantifiable pain-related response that can be used to evaluate the effects of various analgesic interventions.

Review Case Reports
Successful reduction for a pediatric chronic atlantoaxial rotatory fixation (Grisel syndrome) with long-term halter traction: case report.
Clinical case report of atlantoaxial rotatory fixation (AARF) in a girl presenting with torticollis and neck pain. ⋯ From this case, we suggest that long-term traction could be another treatment method for chronic AARF, especially in children.
