Potentially serious spinal conditions include tumor, infection, spinal fracture, or a major neurologic compromise, such as cauda equina syndrome.

Infection. Vertebral osteomyelitis, diskitis, epidural abscess

Tumor. Osteoma, multiple myeloma, skeletal metastases.

Endocrinologic and Metabolic Disorders. Osteoporosis with osteomalacia.

Referred Pain. Abdominal aortic aneurysm, kidney stone, pyelonephritis.

 Markers for Potentially Serious Conditions


Tumor or Infection

Cauda Equina Syndrome

Major trauma, such as a vehicle accident or a fall from height.

New onset or worsening of back pain after minor trauma or strenuous lifting in an older or osteoporotic patient

Age >50 or <20. History of cancer, fever, chills, weight loss. Pain worsens at rest or when supine; severe nighttime pain.

Risk Factors for Spinal Infection: Recent bacterial infection, UTI, IV drug abuse, diabetics, immunosuppression.
