narcotics • Ice• Bracing

• Treatment

Low Back Pain

Determine source of symptoms:• Lumbar disk• Facet joint• Spinal nerves• Vertebral body• Soft tissues• Hip or sacroiliac joint

Low Back Pain Diagnostic Tests

• X-Rays• MRI• CAT scan +/- myelogram• Discogram• EMG• Bone scan• Injections

Low Back PainLong-Term Management

• Therapy/Conditioning

• Lifestyle changes

• Medication

• Injections

• Surgery

Low Back PainLong-Term Management

The goal of long-term management is to reduce stress and strain on the back by strengthening the muscles surrounding the spine and eliminating activities or habits which accelerate the degenerative process.

• Prescription NSAID’s: Lodine, Arthrotec, Mobic, Celebrex

• Narcotics• Anti-Depressants• Anti-Convulsants

TreatmentInjections

• Epidural

• Selective nerve root block (SNRB)

• Facet joint block

All injections should be done with x-ray guidance!

Lumbar Spine Surgery

Surgery of the low back is best directed toward relief of pain originating from a compressed or irritated nerve root(s).

Low Back PainSurgical Treatment of Sciatica

• Laminectomy• Discectomy• Sometimes fusion

is also performed.

Low Back PainSurgical Treatment of Sciatica

• Short procedure (1hr. Average)

• < 24 hour hospital stay

• Good-excellent results in most patients

Surgery for

Chronic Low Back PainTraditional• Lumbar fusionNew Options• IDET• Kyphoplasty/vertebroplasty• Artificial disc replacement (ADR)

Lumbar Fusion

• Combined

Surgical Treatment of Low Back Pain

New Options

• Intradiscal Electrothermal Annuloplasty (IDET)

• Artificial disc replacement (ADR)

• Vertebroplasty / Kyphoplasty

IDET

• A metal coil is inserted into a disc.

• The coil is heated and seals a painful tear.

• Outpatient procedure under IV sedation.

IDET

IDET

Indications:

• One or two painful discs with a tear.

• No prior surgery.

• Well preserved disc height.

Results:

• 60% Good to Excellent results

• Anterior abdominal incision.

• Disc is completely removed.

• Artificial disc is placed.

• Hospital stay of 1-2 days.

Artificial Disc Replacement

Artificial Disc Replacement

Criteria:• 1-2 degenerated disks• Good disk height• No facet arthritis• No prior surgery• No sciatica

70-80% good to excellent results in properly selected patients.

Artificial Disc Replacement

• Best results seem to correlate with less motion (I.e. fusion).

Kyphoplasty / Vertebroplasty

• Cement is injected into a broken vertebrae.

Kyphoplasty / Vertebroplasty

• Balloon is used to create cavity prior to injection of cement with kyphoplasty.

• Outpatient procedure often with immediate pain relief.
