Back pain

Back pain is the second reason responsible for absenteeism from work after the common flux.

Back pain is one of humanity's most frequent complaints.

Back pain is pain felt in the back that usually originates from the muscles, nerves, bones, joints or other structures in the spine.

Back pain affects 80% of adults at some point of their life and occurs at all ages.

Back pain may have a sudden onset or can be a chronic pain; it can be constant or intermittent, stay in one place or radiate to other areas. It may be a dull ache, or a sharp or piercing or burning sensation. The pain may radiate into the arms and hands as well as the legs or feet, and may include symptoms other than pain. These symptoms may include tingling, weakness or numbness.

Less helpful than the history in identifying patients who may be harboring conditions such as cancer, but may be more helpful in detecting spinal infections.

1. spinal infection: findings that suggest this as a possibility (but are also common in patients without infection)

a) fever: common in epidural abscess and vertebral osteomyelitis, less common in discitis

b) vertebral tenderness

c) very limited range of spinal motion

2. findings of possible neurologic compromise: the following physical findings will identify most cases of clinically significant nerve root compromise due to L4–5 or L5–1 HLD, which comprise > 90% of cases of radiculopathy due to HLD; limiting the exam to the following might not detect the much less common upper lumbar disc herniations, which may be difficult to detect on PE

a) dorsiflexion strength of ankle and great toe: weakness suggests L5 and some L4 dysfunction

b) achilles reflex: diminished reflex suggests S1 root dysfunction

c) light touch sensation of the foot:

● diminished over medial malleolus and medial foot: suggests L4 nerve root involvement

● diminished over dorsum of foot: suggests L5

● diminished over lateral malleolus and lateral foot: suggests S1

d) straight leg raising (SLR); also check for crossed SLR


Initial assessment consists of a history and physical examination focused on identifying serious underlying conditions such as fracture, tumor, infection or cauda equina syndrome. Serious conditions presenting as low back problems are relatively rare.

The value of early diagnostic imaging in older adults for back pain without radiculopathy is uncertain 1).

The following information has been found to be helpful in identifying patients with serious underlying conditions such as cancer and spinal infection.

1. age

2. history of cancer (especially malignancies that are prone to skeletal metastases: prostate, breast, kidney, thyroid, lung, lymphoma/myeloma)

3. unexplained weight loss

4. immunosuppression: from steroids, organ transplant medication, or HIV

5. prolonged use of steroids

6. duration of symptoms

7. responsiveness to previous therapy

8. pain that is worse at rest

9. history of skin infection: especially furuncle

10. history of IV drug abuse

11. UTI or other infection

12. pain radiating below the knee
