Description

++

  • Common, degenerative spinal condition
  • Associated with narrowing of the spinal canal (central stenosis) or foraminal canals (lateral stenosis)
  • Caused by degenerative changes to intervertebral discs and facet joints
  • Can result in spinal cord compression, cauda equina compression, or nerve root compression

++

Essentials of Diagnosis

++

  • Can result in neurogenic claudication, with pain, cramping, paresthesias in the lower limbs aggravated by walking and relieved by sitting or flexion
  • Diagnosis made by clinical examination
  • Differentiation between vascular and neurologic claudication
  • Reproduction of symptoms in specific postures and activities

++

General Considerations

++

  • Lumbar spinal stenosis can result in spinal cord compression, loss of bowel and bladder control
  • Cervical central stenosis can cause bilateral symptoms in lower extremity

++

Demographics

++

  • Prevalence increases with age
  • Primarily occurs people aged 65 years or older

++

Signs and Symptoms

++

  • Unilateral or bilateral leg pain with lumbar stenosis
  • Pain worsens with walking, relieved by sitting
  • May be with or without low back pain or neck pain
  • Altered sensation, motor control, reflexes in the distribution of involved nerve roots

++

Functional Implications

++

  • Difficulty walking longer distances
  • Difficulty with standing activities
  • Possible bowel or bladder dysfunction

++

Possible Contributing Causes

++

  • Postural changes
  • Weakness of core musculature
  • Tightness of hip flexors, external rotators, hamstrings

++

Differential Diagnosis

++

  • Vascular insufficiency
  • Peripheral nerve impairment
  • Hip pathology with radiating pain pattern
  • Osteoarthritis
  • Spinal tumor
  • Peripheral neuropathy
  • Degenerative disk disease

++

Imaging

++

  • MRI helpful in diagnosis to visualize compressed or inflamed nerve root
  • X-ray/plain film radiograph helpful if osteophyte located in intervertebral foramen3
  • CT scan to show herniation compressing the spinal canal/nerves
  • Electrodiagnostic/nerve conduction testing can assist to determine a specific impaired nerve function
  • Doppler ultrasound to examine vascular function

++

++

  • To hospital for imaging
  • To physician for surgical consult if myelopathy suspected
  • To physician for imaging and medical consult if disease suspected
  • To physician for If vascular insufficiency suspected

++

  • Hypomobile lumbar ...
