Overview
The cauda equina is a collection of nerves at the end of the spinal cord. Cauda equina syndrome is due to compression of these nerves. It is an emergency medical condition requiring acute intervention in the form of acute decompression surgery to prevent permanent neurological damage to the urinary bladder, Intestine, sex organs and lower limbs.
Historical perspective
Classification
Cauda equina syndrome may be classified into complete and incomplete.[1][2]
- Cauda equina complete with urinary retention
- Cauda equina syndrome incomplete
Pathophysiology
Cauda equina syndrome is caused by compression of the lumbar and sacral nerves roots arising below the conus medullaris.[2]
Causes
Cauda equina syndrome may be caused by[3]
Differentiating cauda equina syndrome from other Diseases
Epidemiology and Demographics
The incidence of cauda equina syndrome is 2 per 100,000 world wide.[1]
Risk Factors
Screening
Natural History, Complications, and Prognosis
Diagnosis
Diagnostic Study of Choice
History and Symptoms
The most common symptoms of cauda equina syndrome include
- Intermittent Lower back pain radiating to the lower extremities. [2][3]
- Decreased muscle strength bilaterally.[3][2]
- Fecal incontinence[3][2]
- Urinary incontinence/ retention[1][3][2]
- Unilateral or bilateral sciatica[2]
- Saddle anesthesia[2]
Physical Examination
- Hypesthesia[3]
- Lasegue sign[3]
- Decreased knee and ankle reflex bilaterally. [3]
Laboratory findinds
X-ray
Ultrasound
CT Scan
Lumbosacral CT scan may be helpful in the diagnosis of cauda equina syndrome. Findings on CT scan suggestive of/diagnostic of cauda equina syndrome include
- CT scans show herniated nucleus pulposus at the L4/5 level.
MRI
Lumbosacral MRI may be helpful in the diagnosis of cauda equina syndrome.[3][2] Findings on MRI suggestive of/diagnostic of cauda equina syndrome include
- In Lumbar disc herniation, MRI shows a disc mass filling most of the spinal canal compressing the cauda equina.
Other Imaging Findings
Other Imaging Findings
Treatment
Medical Treatment
Surgery
Surgery is the mainstay of treatment for cauda equina syndrome.[2][3] Procedures used include
- Hemilaminectomy
- Transforaminal lumbar interbody infusion
