Low Back Pain

“One would have thought by now that the
problem of diagnosis and treatment would
have been solved, but the issue remains
mysterious and clouded with uncertainty.”

and management in the primary care setting. Med Clin

Introduction to Ed

Ed has had lower back pain for the past 24
hours that he feels is related to yard work
that he did over the weekend. He missed

Medications

Anti-inflammatory medications (NSAID’s):
– Beneficial; no differences; watch side-effects

Tylenol:
 Narcotic Pain Relievers:
– No more effective than NSAID’s
– Many side effects

Muscle Relaxants (ie. Flexeril®):
– Can decrease pain and improve mobility
– 70% with drowsiness/dizziness

Chiropractic/Osteopathic

Davenport, Iowa in 1895 by David Palmer;
‘done by hand’ (Greek)
 Spinal manipulation
 Conflicting evidence on the effects of spinal
manipulation
– ~75-90% improvement anyway within 4 weeks

Greater patient satisfaction
3/4/03
Steven Stoltz, M.D.
Exercise & Bed Rest

Advice to stay active:
– ‘There is no evidence that advice to stay active
is harmful for either acute low back pain or
sciatica.’
– Hurt does not equal harm

One or two days of bed rest if necessary
 Light activity, avoiding heavy lifting,
bending or twisting (ie. walking)
 No data on any particular exercises
3/4/03
Steven Stoltz, M.D.
Massage & Physical Therapy

Might be beneficial
 More quality research is needed
 Different types of massage
3/4/03
Steven Stoltz, M.D.
Acupuncture

Very little quality research and data
 Seems to indicate that acupuncture is not
effective for the treatment of back pain

Other Modalities

Back Brace/Corset/Lumbar Support:
 Traction:
 Injections: Inconclusive evidence
 TENS:
 Hot/Cold:
 Ultrasound:

Ed, again…

Now, Ed has not had improvement in his
lower back pain and 6 weeks have gone by
since the initial painful event.
 What types of therapies might be beneficial
for Ed now?
3/4/03
Steven Stoltz, M.D.
Role of X-rays (Radiology)

Usually unnecessary and not helpful
 Plain X-ray:
– Age>50 years
– No improvement after 6 weeks
– Other worrisome findings

MRI:
– After 6 weeks if have sciatica

Medications
Similar to acute pain….
 Antidepressant medications can improve
pain relief


Exercises

Improves pain and function
 Many programs available, but difficult to
make any scientific recommendations for
one type versus another
3/4/03
Steven Stoltz, M.D.
Injections

Epidural injections:
– Insufficient and conflicting evidence

Facet joint injections:
– No improvement

Local/Trigger point injections:
– Possibly some benefit

Surgery

Diskectomy improves pain in short term but
not long term (ie. 10 years)
 Microdiskectomy similar to standard
diskectomy
 Automated percutaneous diskectomy and
laser diskectomy both less effective
 ? Arthroscopic diskectomy

Other Modalities

Back Schools: - possibly effective
 Multidisciplinary Therapy: - probably yes
 TENS: - no
 Spinal manipulation: - conflicting data
 Massage: - probably yes
 IDET:

Intradiscal Electrothermal Therapy

Steven Stoltz, M.D.
IDET

No convincing evidence that shows the
short or long-term clinical efficacy of this
procedure.
 Safe with few adverse effects
 ? Long-term effects

Prevention

Exercise:
– Aerobic, back/leg strengthening

Back braces and education about proper
lifting techniques are ineffective
 ? weight loss and smoking cessation
