TEST 3: Lumbar Spine SD Dx Flashcards
incidence of low back pain
- 85% of general public have low back pain
- in 35% of adolescent athletes
- overuse injuries are prone to recurrence
- 27% of back pain in adults is due to MSK strains
what are some general considerations to remember when treating pts with low back pain?
- it is the number #2 reason its go to the doctor
- majority of causes do not require surgical intervention
- massive financial burden (cost of tx, expense of lost work, legal costs)
- emotional burden (inc stress, depression)
what is the majority of back pain due to?
mechanical dysfunction
lumbar spine is frequent site of:
- strain
- pain
- disability
anatomy of lumbar spine
- vertebrae are built to support heavy loads
- allows for flexion/extension
- less SB and rotation due to sagittal orientation of facets
lumbar herniated disc
- may compress lumbar spinal nerve
- may tear the annular ligament
mechanical etiologies of low back pain
- arthritis
- spondylosis/ spondylolysis/ spondylolisthesis
- degenerative disc dz
- somatic dysfunction
non-mechanical etiologies of low back pain
- viscerogenic

- infection
- tumors
- metabolic
- rheumatologic
