The outstanding symptom associated with compression of a nerve root by a herniated lumbar dise is pain radiating down the posterolateral aspect of the lower extremity. The key physical finding in examining such a patient is reproduction of this pain on elevating the leg with the knee extended. In addition to pain, compression of the lumbosacral nerve roots will produce radiculopathy characterized by numbness, weakness and/or loss of deep tendon reflexes.
