Abstract: Lumbar canal stenosis is an anatomical term used to describe narrowing of the spinal canal either congenitally or from age-related degenerative changes. It refers to a structural finding that may or may not be symptomatic. A decrease in canal diameter can lead to compression of the neural components, causing a constellation of symptoms. Family physicians should familiarize themselves with the various presentations of canal narrowing and the available diagnostic and treatment options.
Key Words: lumbar spinal stenosis, neurogenic claudication, back pain, radiculopathy.

1. Lumbar spinal stenosis is commonly caused by age-related degenerative changes involving the intervertebral discs, ligamentum flavum and facet joints.
2. Patients with lumbar spinal stenosis may present with neurogenic claudication or radiculopathy.
3. The primary care provider needs to distinguish between symptomatic lumbar spinal stenosis and other common mimics.
4. Surgical treatment is principally decompression of the neural elements with the possible addition of fusion of the affected levels.
1. Degenerative changes in the lumbar spine can lead to various symptoms such as low back pain, lumbar radiculopathy, neurogenic claudication, and cauda equina syndrome.
2. Imaging of the lumbar spine should be ordered when there is a high clinical suspicion of lumbar spinal canal stenosis based on the history and physical examination.
3. Initial management of patients presenting with lumbar canal stenosis involves non-operative modalities like pharmacological therapy, physiotherapy, lifestyle modifications, patient education and image-guided injections.
4. Surgical decompression for symptomatic lumbar spinal stenosis, with or without fusion, is generally indicated when symptoms significantly interfere with daily activity and non-operative treatment has failed after 3-6 months.

Lumbar spinal stenosis (LSS) is the leading cause of spinal surgery among older Americans, yet more than one-third do not gain significant relief from surgical treatment. The distinct pattern of lower back and leg pain induced by standing and walking associated with LSS is known as neurogenic intermittent claudication (NIC). Various treatment options for NIC include surgical interventions as well as pharmacological, biomechanical and conservative therapy (i.e., physical therapy). No specific treatment is associated with guaranteed outcome, which underscores the need to further evaluate the diagnosis and symptoms associated with LSS.

Degenerative lumbar spinal stenosis is a common problem among older adults. Stenotic compression of spinal nerves can result in low back pain, disabling leg pain, and greatly restricted walking capacity. Conservative therapies are usually prescribed for mild symptoms and surgery is prescribed for severe symptoms, while patients with moderate symptoms may not have an obvious treatment choice. The clinical evidence supporting these treatment options has been criticized because of problems with study design and quality that complicate their assessment. Despite the poor quality of most of the literature, recent studies provide better information and a means of starting to judge the effectiveness of treatment.
