A validation study of the Acute Low Back Pain Screening Questionnaire Dutch Language Version (ALBPSQ-DLV). ⋯ The internal consistency and both construct and convergent validity of the ALBPSQ-DLV are well established in a Dutch population of 69 patients with (sub) acute nonspecific LBP referred to primary care physical therapy.
-
Laboratory investigation, ex vivo. ⋯ The low degree of heating and minor artifacts associated with the Resolve-based cervical external immobilization devices indicated that these products are safe for patients undergoing MRI at 3-Tesla.

Case Reports
High rectal injury during trans-1 axial lumbar interbody fusion L5-S1 fixation: a case report.
A case report. ⋯ We report a case of high rectal injury during Trans-1 axiaLIF L5-S1 fixation and strongly advice that patients who are candidates for this surgery and have any risk factors for intra-abdominal adhesion formation, undergo a pelvic CT with rectal contrast before the surgery to evaluate for any signs of altered rectal-sacral anatomy.
-
Case report. ⋯ We present the first report describing a case of anterior spinal cord syndrome caused by a cement embolism in the anterior spinal artery after vertebroplasty. The severity of this complication warrants that surgeons should inform patients of the same while obtaining their consent for vertebroplasty.

Mechanical testing of cadaveric spines. ⋯ When the ageing spine is compressed, vertebral bodies show greater elastic deformations than intervertebral discs, and creep by a similar amount. Responses to axial compression depend largely on IDP, but deformations appear to be limited by impaction of adjacent neural arches. Total compressive deformations are sufficient to cause foraminal stenosis in some individuals.
