Lumbar Spinal stenosis: new update by Review of Literature

Degeneration of the intervertebral disc results in initial relative instability, hypermobility, and hypertrophy of the facet joints, particularly at the superior articular process. This finally leads to a reduction of the spinal canal dimensions and compression of the neural ele­ments, which can result in neurogenic intermittent claudication caused by venous congestion and arterial hypertension around nerve roots. We make a decision to review of 66 articles from 1980 to 2016 in this condition. Most patients with symptomatic lumbar stenosis had neurogenic intermittent claudication with the risk of a fall. However, al­though the physical findings and clinical symptoms in lumbar stenosis are not acute, the radiographic findings are comparatively severe. Differentiation between neurogenic and ischemic claudication is important Magnetic resonance imaging is a noninvasive and good method for evaluation of lumbar stenosis. Though there are very few studies pertaining to the natural progression of lumbar spinal stenosis, symptoms of spinal stenosis usually respond favorably to non-operative management. In patients who fail to respond to non-operative management, surgical treatments such as decompression or decompres­sion with spinal fusion are required. Restoration of a normal pelvic tilt after lumbar fusion correlates to a good clinical outcome.currently, the interest to minimally invasive approaches like bilateral laminotomy, Trumpet laminectomy, and conventional laminectomy is increased.
