Lumbar spine - Basic info - Low back pain …?
Is the MC musculoskeletal complaint in the outpatient setting.
Lumbar spine - …% of the population experience low back pain at some time in their life.
80%.
Low back pain is generally a …?
SELF-LIMITED CONDITION.
50% are better in ONE WEEK.
90% are better in 6 WEEKS.
Sciatica can have a …?
More protracted course.
==> 50% recover in 4 weeks.
Low back pain - LOCAL CAUSES:
- Muscle strain.
- Lumbar spine osteoarthritis.
- Degenerative disk disease.
- Vertebral body infection.
- Disk space infection.
- Vertebral body malignancy.
- Compression fracture.
- Spinal stenosis.
Low back pain - Referred/Distant causes:
- Ulcer disease.
- Pancreatitis.
- Nephrolithiasis.
- Prostatitis.
- Aortic dissection.
- Subacute BACTERIAL ENDOCARDITIS.
- Pelvic pathology.
Low back pain - Worrisome findings:
- NOCTURNAL PAIN ==> Malignancy, infection.
- WRITHING PAIN ==> Aneurysm, perforated viscus.
- Evolving neurologic deficits (leg weakness, bowel/bladder incontinence) ==> Epidural abscess, hemorrhage, disk herniation, cauda equina syndrome.
- Fever ==> Infection.
Spinal stenosis:
- Caused by impingement on lumbosacral spinal cord.
- Associated with degenerative arthritis.
- Pseudoclaudication (non vascular claudication improving with flexion at the waist).
Straight leg raise test:
- Sensitive (more than 90%) but NOT specific.
- Pain should be radicular.
- Helpful in ruling out sciatica.
- Crossed straigth leg test less sensitive (25%) but more specific (80%).
Indication for radiographic evaluation:
- Preceding significant trauma.
- Evolving neurologic findings.
- Suggestion of malignancy or infection.
- New onset pain at an older age.
- Persistent pain.
Low back pain - Tx:
- Rest.
- Heat and cold.
- NSAIDs.
- Physical therapy.
- Surgery may be indicated (eg infection, intractable pain, neurologic defects, and spinal stenosis).
