Abstract
|
|
|
The tethered syndrome is a clinical entity manifested by progressive motor and sensory changes in the legs, incontinence, back or leg pain and scoliosis. In order to elucidate the pathophysiology involved in the tethering effect of the cord, regional spinal cord blood flow (rSCBF) and somatosensory evoked potential (SEP) were measured in tethered cord animals.
Studies in experimental tethered cord models indicate marked reduction of rSCBF, and suppressed SEP at the adjacent area of traction (L_(1)) L_(1), under traction with greater weight (5 or 10 gm). It is assumed that prolonged and progressive neuronal dysfunction may lead to structural damage of neurons caused by impairment of blood flow.
Untethering procedures in tethered cord may improve blood flow and probably facilitate the repair mechanism´ of injured neurons.
