Breakthroughs in treatment of spine and back conditions

http://www.eurekalert.org/pub_releases/2010-03/aaoo-bit030410.php

Approximately 21 million visits were made to physicians' offices due to back

problems in 2006. While countless adults experience back pain and stiffness,

many suffer from serious spine and back conditions –including injury, herniated

discs and the deterioration of the vertebrae. Three new studies presented at the

2010 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS)

detail advances in back care and treatment options for specific back and spine

conditions. Each of the following three studies consider and report on the

patients' best outcomes and options:

•Does the duration of symptoms affect outcomes in the treatment of lumbar disc

herniation?

•Treatment of Lumbar Spinal Stenosis: Who Decides to Have Surgery?

•Balloon Kyphoplasty vs Non-surgical Care: 2 Year Outcome of a Randomized

Controlled Trial

Slipped Disc: When to Seek Treatment?

Lumbar disc herniation, or a slipped disc, mainly affects adults aged 30 to 40

years and is commonly caused by degenerative changes in the spine. Typically,

these changes produce symptoms gradually, beginning with pain centered in the

lower back. With progression of the condition, patients may suffer from extreme

back pain and that also may spread into the buttocks and down the legs.

A new study released today analyzed the effect of symptom duration when treating

herniated discs in the lower back. A comparison was made between 927 patients

who had intervertebral lumbar disc herniation symptoms for less than six months

and 265 patients who had symptoms longer than six months. Patients with symptoms

lasting longer than six months had worse outcomes after both operative and

non-operative treatment than patients with shorter symptom duration.

" The bottom line is patients who seek treatment, whether it is surgical or

non-surgical, during the first six months of symptoms will respond better to

treatment, " said A. Rihn, MD, study co-investigator and assistant

professor, Department of Orthopaedic Surgery, Jefferson University and

The Rothman Institute. " We also learned that surgery offers advantages over

non-surgical treatment regardless of the duration of symptoms. "

Spine Injury in Seniors: Is Surgery For You?

Lumbar spinal stenosis is the leading cause of spine surgery in patients over

age 65. Spinal degeneration narrows the spinal canal and compresses the spinal

cord and nerves. Previous studies have demonstrated the benefit of surgery over

non-surgical management of this condition, however, in these studies it was

unclear what were the indications for surgery and largely unknown which patients

select surgery.

The study unveiled today looked at 241 patients who underwent surgery and 115

who had non-operative care. Researchers found that patients who chose surgery

tended to be:

•Younger;

•With more pain and more disability; and

•Felt their symptoms were progressing.

" These results help complete the evaluation and treatment algorithm for patients

with spinal stenosis. The findings will enhance the shared decision-making

process by aiding physicians in counseling patients to help them choose the

right treatment option, " explained Mark F. Kurd, MD, lead author of the study

and orthopaedic surgery resident, Jefferson University and The Rothman

Institute.

Vertebral Fractures: Surgical or Non-Surgical Care?

Vertebral compression fractures are one of the most frequent consequences of

osteoporosis. They cause pain, disability and diminished quality of life.

Current non-surgical treatment options involve pain medication, bed rest,

physiotherapy and back bracing. However these options do not address the

resulting vertebrae breakdown, height loss and other resulting problems.

Balloon kyphoplasty is a minimally invasive procedure for acute vertebral

fractures that reduces and corrects the vertebral deformity by inserting

expandable balloon tamps and then filling it with bone cement. In 2007, 46,000

inpatient kyphoplasty procedures were performed in the United States, according

to the Nationwide Inpatient Sample, Healthcare Cost and Utilization Project

coordinated by the Agency for Healthcare Research & Quality.

Results were presented today from a study of 149 patients treated with balloon

kyphoplasty and 151 patients treated with non-surgical treatment. Measurements

for quality of life, back pain and function, and days of disability were

assessed through 24 months of follow-up. Compared to non-surgical care, balloon

kyphoplasty:

•Improved quality of life;

•Reduced back pain and disability; and

•Did not increase adverse events including the risk of vertebral fracture over

two years.

" I have been using balloon kyphoplasty to treat patients with painful vertebral

compression fractures for years so the immediate and sustained pain relief we

saw in the study did not surprise me, " concluded Jan Van Meirhaeghe, MD, study

co-author and orthopaedic surgeon, Department of Orthopaedic Surgery, St-Jans

Hospital, Brugge, Belgium and Gent University Hospital, Gent, Belgium. " But

until now these decreased pain levels and significant quality of life

improvement, as compared to non-surgical treatment, had not been demonstrated in

a clinical trial. "
