radiculopathy
Pronunciation: rah-dik-yoo-LOP-ah-thee
Dysfunction of nerve roots causing pain, numbness, or weakness in the distribution of the affected nerve.
Full Definition
A condition resulting from compression, inflammation, or injury to nerve roots as they exit the spinal cord through the neural foramina. Radiculopathy typically causes pain, numbness, tingling, or weakness that follows the specific dermatomal and myotomal distribution of the affected nerve root. In the lumbar spine, this commonly presents as sciatica, while cervical radiculopathy may cause symptoms in the arms and hands.
Usage
Usage note: Distinguish from myelopathy (spinal cord dysfunction) and peripheral neuropathy.
