Overview

Cauda Equina Syndrome
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.
Ankylosing Spondylitis
Ankylosing spondylitis is a chronic inflammatory condition that mainly affects the spine and the joints connecting the spine and pelvis. It commonly causes lower back or hip pain and stiffness that may worsen after periods of rest and improve with movement. In some people, inflammation can also affect other joints, the eyes, skin, or digestive system.

Diagnosis

Cauda Equina Syndrome
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.
Ankylosing Spondylitis
Diagnosis of ankylosing spondylitis is based on symptoms, physical examination, medical history, and imaging. X-rays may show changes in the sacroiliac joints or spine, while MRI can detect inflammation earlier in the disease. Blood tests may include markers such as C-reactive protein and testing for HLA-B27. No single test confirms the condition in every person.

Prevention

Cauda Equina Syndrome
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.
Ankylosing Spondylitis
Ankylosing spondylitis cannot currently be prevented because its exact cause is unknown and genetic factors play an important role. People with a strong family history or persistent inflammatory back symptoms should seek medical evaluation. Early diagnosis and appropriate management, including regular physical activity and exercises recommended by healthcare professionals, can help maintain mobility and posture.

Risk Factors

Cauda Equina Syndrome
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.
Ankylosing Spondylitis
Risk factors include a family history of ankylosing spondylitis and genetic susceptibility, particularly the HLA-B27 gene. Symptoms commonly begin before age 45. People with inflammatory bowel diseases such as Crohn disease or ulcerative colitis, or with psoriasis, may also have increased risk of developing ankylosing spondylitis.
