General Information
Patients may describe neck or flank pain as back pain
Back pain
Common: In any given 3 month period, affects 25% of American adults
Definitions
Acute: Duration < 4 weeks
Subacute: Duration 4-12 weeks
Chronic: Duration > 12 weeks
Neck Pain
Facet arthrosis: Neck pain predominant
Cervical radiculopathy: Arm pain predominant
Central stenosis
Foraminal stenosis
Disc herniation
Additional considerations
Atlantoaxial and/or atlanto-occipital joint pathologies
Shoulder pain radiating to neck
Back Pain
Adult
Non-specific back pain
Radiculopathy/spinal stenosis
Spinal stenosis
Spondylolisthesis: Intervertebral disc degeneration → intersegmental instability and facet joint arthropathy
Conditions
Cauda equina syndrome: Leg weakness, urinary retention, fecal incontinence, saddle anesthesia - MRI - steroids, surgical decompression within 24 hours
Trauma/Fracture
Infection: Osteomyelitis, epidural abscess
Lytic lesions/malignancy
Multiple myeloma
Metastatic breast cancer, lung cancer, and/or prostate cancer
ROS and Referral Pattern
Potential Neurosurgical Emergency
Trauma → ED
Urinary retention, fecal incontinence, weight loss, lower extremity weakness/sensory deficit → ED, orthopedics, or neurosurgery
Concern for Infection/Malignancy
Fever, chills, night sweats → ED or infectious disease
History of HIV, chronic corticosteroid use, IV drug use → Infectious disease
History of malignancy, unexplained weight loss → Orthopedics or oncology
Thoracic pain, night pain → Orthopedics
Additional Considerations: Compression fracture (osteoporosis), ankylosing spondylitis
Pediatric
More Common
Acute: Muscle strain, spondylolysis/spondylolisthesis, slipped apophysis
Chronic
Scoliosis: Early onset (childhood) vs. adolescent idiopathic
Inflammatory spondyloarthropathies
Red flags: Fever, weight loss, and/or back pain at night
Tumor: Osteoid osteoma, osteoblastoma, spinal cord tumors
Infection: Osteomyelitis, discitis
Flank Pain
Acute pyelonephritis
Ruptured abdominal aortic aneurysm
Gastrointestinal
Acute cholecystitis, etc.
