STUDY DESIGN A 2-part cadaveric study. OBJECTIVES Part 1: To assess the reliability of a semiquantitative classification system for grading lumbar spine foraminal stenosis and the variability in magnetic resonance imaging (MRI) examinations carried out in different institutions. Part 2: to assess the difference between the foraminal measurements carried out on MRI images and on cadaveric spec...

BACKGROUND A lipo-prostaglandin E1 agonist is effective for the treatment of neurological symptoms of spinal stenosis when administered by an oral or intravenous route. we would like to reveal the therapeutic effect of an epidural injection of lipo-prostaglandin E1 on hyperalgesia in foraminal stenosis. METHODS A total of 40 male Sprague-Dawley rats were included. A small stainless steel rod ...

Even though most vertebral artery anomalies are asymptomatic, but the normally arising from superoposterior surface of its ipsilateral subclavian artery, plays a vital role, via Subclavian Steal Syndrome to help in vascularization upper limb anatomical structures. The case left with proximal origin stenosis 72 year -old female cadaver is reported and pathophysiological consequences an hypothesi...

Objective. The aim of this study was to evaluate the efficacy of a three-dimensional (3D) turbo spin-echo (TSE) sequence for determining lumbar disc protrusions, and to compare the findings with those of conventional two-dimensional (2D) TSE sequences and reveal the interobserver and intermethod agreements of both sequences. Methods. A total of 127 discs from 84 patients were evaluated by three...

Posterior lumbar interbody fusion (PLIF), as recommended with bilateral lumbar interbody cages and pedicle screw fixation, has increased the successful fusion rate to nearly 100%. Presently, a unilateral approach to the disc space with a variant of PLIF, the trans-foraminal interbody fusion is often used. There are few clinical studies of unilateral interbody fusion. The clinical and fusion res...

BACKGROUND Posterior cervical foraminotomy is a valuable treatment option for cervical radiculopathy. Here the authors present their technique and results in the treatment of a series of patients suffering from osseous foraminal stenosis. METHODS Forty-three patients suffering from cervical osseous foraminal stenosis were operated on via a posterior approach with the EasyGO endoscopic system....

The authors described the case of a 39-year-old man with Klippel-Trénaunay syndrome, who had an extradural meningeal cyst expanding into intervertebral foramen of lumbar 2 and 3 vertebrae. The patient suffered from low back pain radiating to the left lower extremity. Magnetic resonance imaging revealed a huge extradural meningeal cyst growing through intervertebral foramen far laterally. A wide...
