Spinal stenosis. A common cause of podiatric symptoms.
Spinal stenosis, involving pressure on either the central spinal cord or nerve root exiting the spinal canal, can cause a variety of symptoms in the lower extremities. A classic symptom is that of neurogenic claudication, involving leg pain and weakness brought on by walking. The pain is relieved by sitting or lying down, not by standing and resting as would be seen in arterial insufficiency-induced claudication. Other symptoms of spinal stenosis can involve paresthesia, weakness or cramping in one or both extremities, rest pain, or burning pain, and are commonly misdiagnosed as peripheral neuropathy, especially in patients with diabetes. Symptoms are often chronic, frequently missed, or misdiagnosed in the medical community, and may cause severe disability or reduction in the quality of life. Spinal stenosis is in some patients the unidentified cause of failure of treatment of foot and leg pain. Podiatric physicians, who focus on the patient's lower extremities, are in a unique position to be able to identify spinal stenosis and facilitate appropriate treatment. The authors provide current information regarding symptoms of spinal stenosis, a guide to diagnosis including the anatomical etiologies, and a basic understanding of treatment.
