<unk>  <unk>  is a condition that occurs when the bundle of nerves below the end of the spinal cord known as the<unk><unk>  is damaged. Signs and symptoms include low back pain, pain that radiates down the leg, numbness around the anus, and loss of bowel or bladder control. Onset may be rapid or gradual. The cause is usually a disc herniation in the lower region of the back. Other causes include spinal stenosis, cancer, trauma, epidural abscess, and epidural hematoma. The diagnosis is suspected based on symptoms and confirmed by medical imaging such as MRI or CT scan.<unk>  is generally treated surgically via laminectomy. Sudden onset is regarded as a medical emergency requiring prompt surgical decompression, with delay causing permanent loss of function. Permanent bladder problems, sexual dysfunction or numbness may occur despite surgery. A poor outcome occurs in about 20% of people despite treatment. About 1 in 70,000 people is affected every year. It was first described in 1934.
