An expert algorithm to assist in the diagnosis of back pain can be found here
Overview
There are several life-threatening causes of back pain which need to be evaluated for first, which include; spinal cord or cauda equina compression, aortic dissection, aortic aneurysm, vertebral osteomyelitis, epidural abscess, and metastatic cancer. The other possible causes of back pain can be evaluated for by carefully assessing the nature of the pain, and obtaining a thorough patient history.
Differential Diagnosis
- 5 life threatening diseases to exclude immediately:[1][2][3][4][2][3][5][6][7][8][9][10][11][12][13][14][15][16][17]
- Spinal cord or cauda equina compression
- Aortic dissection
- Aortic aneurysm
- Vertebral osteomyelitis
- Epidural abscess
- Metastatic cancer
- The frequency of conditions exclusive of the above in a descending order is:
- Vertebral compression fracture
- Radiculopathy
- Spinal stenosis
- Ankylosing spondylitis
- Osteoarthritis
- Scoliosis
- Hyperkyphosis
- Psychologic distress
- The frequency of conditions outside the spine exclusive of the above in a descending order is:
- Muscle spasm
- Prolonged sitting
- Piriformis syndrome
- Sacroiliac joint dysfunction
- Bertolotti's syndrome (Lumbosacral transitional vertebrae)
