Paralyzing sciatica - Definition

July 2017


Definition


The term sciatica refers to all pain symptoms related to an irritation of the sciatic nerve. It is frequently caused by pressure exerted on the sciatic nerve at its root, located near the lumbar vertebra. Paralyzing sciatica is a particular form of sciatica, which causes motor impairment in the area innervated by this nerve. Depending on which nerve root is affected, impairment is observed in either the ability to walk on the heels, for the L5 root, or on the toes, for the S1 root. When impairment is noted, a scan or lumbar MRI is required in order to locate the area afflicted and consider surgical options.
