Lumbar Spinal Stenosis:
- Spinal stenosis is defined as narrowing of the spinal canal resulting in compression of spinal cord and/or nerves.
- This can be caused by a bulging disk or dengernative disk disease, hypertrophy or degenerative enlargement of the facet joints, listhesis or movement of one vertebral body over another, hypertrophy and/or calcification of intraspinal ligaments.
- Patients with lumbar stenosis typically results in neurogenic claudication which is unilateral or bilateral buttock, hip, thigh, or leg pain which is brought on by walking or at times even standing. It is commonly relieved by sitting, bending forward, squatting, or lying down. It is thought that these symptoms are caused by reversible ischemia of the nerve roots.
- The physical examination may be normal in a significant number of patients with this condition, with absent or diminished knee and ankle jerks most commonly observed.
