Cauda Equina Syndrome
Emergency
Cauda equina syndrome occurs when the bundle of nerve roots at the lower end of the spinal cord becomes compressed or damaged. These nerve roots control sensation and movement in the legs and help control bladder and bowel function. The condition can develop from a severe disc problem, spinal narrowing, tumor, infection, bleeding or other causes of pressure on the nerve roots. Because permanent nerve damage can occur, suspected cauda equina syndrome is a medical emergency requiring prompt assessment.

Emergency Medical Attention
Cauda equina syndrome is a medical emergency caused by severe compression of the nerves at the lower end of the spinal canal. Seek emergency medical attention immediately for new loss of bladder or bowel control, inability to urinate, numbness around the groin or buttocks, rapidly worsening leg weakness, or major changes in sensation or movement. Prompt treatment is important to reduce the risk of permanent neurological damage.

Overview
Cauda equina syndrome occurs when the bundle of nerve roots at the lower end of the spinal cord becomes compressed or damaged. These nerve roots control sensation and movement in the legs and help control bladder and bowel function. The condition can develop from a severe disc problem, spinal narrowing, tumor, infection, bleeding or other causes of pressure on the nerve roots. Because permanent nerve damage can occur, suspected cauda equina syndrome is a medical emergency requiring prompt assessment.

Causes 1
Cauda equina syndrome is most often caused by severe compression of the nerve roots in the lower spinal canal. A large herniated disc can compress the nerves, while spinal stenosis, tumors, infections, bleeding or traumatic injury can also produce pressure. Other structural conditions affecting the lower spine may contribute. The underlying problem determines how quickly symptoms develop and how much nerve function is affected.
Chronic Disease
Risk Factors
Risk factors depend on the condition causing nerve compression and may include severe or recurrent lumbar disc disease, narrowing of the spinal canal, spinal tumors, infection, bleeding around the spine and significant lower-back trauma. Previous spinal disorders or procedures may also be relevant. People with new severe lower-back symptoms accompanied by changes in bladder, bowel, leg strength or sensation require urgent medical evaluation.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is based on the pattern of neurological symptoms and a physical examination, followed by urgent imaging when cauda equina syndrome is suspected. The healthcare provider will assess leg strength, sensation, reflexes and bladder or bowel function. MRI is commonly used to identify compression of the nerve roots and determine the underlying cause. Other imaging or tests may be needed depending on the suspected cause. Prompt diagnosis is important because prolonged compression can result in permanent neurological problems.
Prevention
Key Prevention Tips
Cauda equina syndrome cannot always be prevented because some causes, such as tumors or sudden severe disc herniation, are not predictable
Reducing the risk of spinal injury through safe lifting practices, appropriate protective equipment and safer driving and recreational activities may help prevent some spinal conditions
People with known spinal disease should follow medical advice and seek prompt evaluation for rapidly worsening back pain, leg weakness, numbness or new bladder and bowel problems
Prevention Guidance
Cauda equina syndrome cannot always be prevented because some causes, such as tumors or sudden severe disc herniation, are not predictable. Reducing the risk of spinal injury through safe lifting practices, appropriate protective equipment and safer driving and recreational activities may help prevent some spinal conditions. People with known spinal disease should follow medical advice and seek prompt evaluation for rapidly worsening back pain, leg weakness, numbness or new bladder and bowel problems.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
