The lumbar epidural region was studied using computerized tomography. This technique allows examination of the region in vivo. It confirmed that the spinal canal is oval in the upper lumbar region, becoming triangular lower down, and that the ligamenta flava form a posterior recess to the vertebral canal. Epidural fat is confined to this region between the ligamenta flava and the intervertebral...

STUDY DESIGN Four conditions (three orthoses, one no orthosis), full cross-over, randomized order, 12 subjects tested 3 months after a lumbar surgical arthrodesis. OBJECTIVES To assess whole torso and lumbar motions and comfort for each orthoses condition during performance of activities of daily living. SUMMARY OF BACKGROUND DATA Previous noninvasive studies measured whole torso (not just ...

Husch A, Cramer N, Harris-Warrick RM. Long-duration perforated patch recordings from spinal interneurons of adult mice. J Neurophysiol 106: 2783–2789, 2011. First published September 7, 2011; doi:10.1152/jn.00673.2011.—It has been very difficult to record from interneurons in acute slices of the lumbar spinal cord from mice 3 wk of age. The low success rate and short recording times limit in vi...

BACKGROUND The aim of this study was to provide information on algometric transmission of pressure through the dorsal thoracolumbar tissues of the equine back. Using a commercially available algometer, measurements were carried out with six different tips (hemispheric and cylindrical surfaces, contact areas 0.5 cm2, 1 cm2, and 2 cm2). In nine live horses the threshold of pressure that lead to a...

The objective of this article is to report an unusual case of a spinal rod that protruded into the spinal canal after lumbar spine surgery.Only 4 cases of spinal rod migration with protrusion into the spinal canal have been reported. This is the first report of a case involving the use of posterior low lumbar segmental instrumentation with a screw-rod system. The left side of the rod gradually ...

BACKGROUND Exposure of the anterior or lateral lumbar via the retroperitoneal approach easily causes injuries to the lumbar plexus. Lumbar plexus injuries which occur during anterior or transpsoas lumbar spine exposure and placement of instruments have been reported. This study aims is to provide more anatomical data and surgical landmarks in operations concerning the lumbar plexus in order to ...

An 80-year-old woman presented with 2 days of progressive quadriparesis, difficulty voiding, and fever. She had received acupuncture in the cervical and lumbar regions for 5 days beginning a week before. Whole-spine MRI showedmultiple epidural abscesses at levels C3-C7, L3-L5, and L5-S1 (figure). Broad-spectrum antibiotics were administered, and the abscesses were surgically drained. Strains of...

Purpose Placebo analgesia refers to a perceived reduction in pain intensity following the administration of a simulated or otherwise medically ineffective treatment. Previous studies have shown that many factors can influence the magnitude of placebo analgesia. However, few investigations have examined the effect of age on placebo analgesia, and none have done it in the context of electrotherap...

OBJECTIVE To evaluate the efficacy of anti-adhesion barrier agents following lumbar microdiscectomy. METHODS Healon GV or Adcon-L was applied to a laminectomy defect overlying the duramater in 60 patients assigned to 3 randomized groups: Group I - Adcon-L (n=21), Group II - Healon GV (n=21), and Group III - control group, no adhesion barrier used (n=18). We conducted this study between 2004 a...

We present a case of multilevel lumbar transverse process fracture in a professional association football player, incurred after a fall from height during competitive play. Traditionally associated with high impact trauma in the general population, this injury is relatively rare in the context of professional football where it is more likely to be associated with lower impact trauma. We outline...
