OBJECTIVE To evaluate the effectiveness of the In- space (Synthes, Umkirch, Germany) and the correlation between radiographic parameters and clinical outcome in patients with lumbar spinal canal stenosis (LSS). METHODS Between June 2009 and May 2013, 56 patients with LSS underwent In-space by one senior surgeon. All of the patients were evaluated both clinically and radiographic measurements ...

INTRODUCTION Accurate morphometric characterization of the lumbar spinal canal is important in understanding low back disorders such as lumbar spinal stenosis. Current conventional methods measuring the AP diameter of the canal, a common parameter for defining the canal, use practical and clinically available methods where patient CT scans are analyzed in 2D. This method, however, does not take...

Objective. Selective, bilateral multisegmental microsurgical decompression of lumbar spinal canal stenosis through separate, alternating cross-over approaches. Indications. Two-segmental and multisegmental degenerative central and lateral lumbar spinal stenosis. Contraindications. None. Surgical Technique. Minimally invasive, muscle, and facet joint-sparing bilateral decompression of the lumbar...

Review scope Included studies compared epidural corticosteroid injections with placebo (administration of an inert or innocuous substance into the epidural space or adjacent spinal tissue) in patients with sciatica. Studies had to report ≥ 1 of overall pain intensity, leg pain intensity, back pain intensity, or disability status. Corticosteroids could be delivered into the epidural space by any...

BACKGROUND The relationship between severity of preoperative radiographic findings and surgical outcomes following decompression for lumbar degenerative spinal canal stenosis is unclear. Our aim in this paper was to gain insight into this relationship. We determined pre-operative radiographic severity on MRI scans using strict methodological controls and correlated such severity with post-opera...

Reports on adolescent patients with cervical myelopathy who underwent anterior cervical discectomy and fusion are scarce. However, to our knowledge, no cases of expansive laminoplasty for cervical myelopathy associated with progressive neurological deficit after a series of conservative treatment, caused by both disc herniation and developmental cervical spinal canal stenosis, have been reporte...

OBJECTIVE Dural sac cross-sectional area (DSCSA) is a way to measure the degree of central spinal canal compression. The objective was to investigate the correlation between the expansion ratio of DSCSA after unilateral laminotomy for bilateral decompression (ULBD) and the clinical results for lumbar spinal stenosis. METHODS We retrospectively reviewed the clinical data and radiographs of 103...

Spinal stenosis in either the cervical or lumbar spinal segments is one of the most common indications for spine imaging and intervention, particularly among the elderly. This article examines the pathophysiology and imaging of the corresponding clinical syndromes, cervical spondylotic myelopathy or neurogenic intermittent claudication. The specificity fault of spine imaging is readily evident ...

4 In the 1 970s there were two outstanding changes which influenced the management of spinal disorders. First, significant advances occurred in investigative methods: safer water-soluble contrast agents became available, leading to improved myelography; computerised tomography heralded a revolution in non-invasive imaging of the spinal canal; ultrasonic measuring techniques were applied to the ...
