When Motion Segment is No More a Motion Segment
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2014, Vol 2, Issue 5
Abstract
The motion segment plays a major role in the biomechanics of spine. Lumbar spine, especially lower lumbar spine, which is mobile and weight bearing, undergoes series of changes as age advances. This segment transforms into a motionless segment due to degenerative spondylosis and lead to a clinical entity called lumbar canal stenosis, which can produce, low back pain and neurological claudication. In such patients internal decompression of stenosed lumbar canal by laminectomy and foraminotomy by excising the medial part of superior facet of inferior vertebra can be a useful surgical option. We report a case series of 98 elderly patients, suffering from severe lumbar canal stenosis secondary to degenerative spondylosis with various neurological complications managed at our institute between October 2010 and May 2013, using the above mentioned surgical option. At two years follow up all patients showed good functional recovery, symptomatic relief and none presented with any spinal instability..
