abraded the edge of the bone . . . to stimulate the periosteum to send in new blood
vessels. So we tried to mimic that with the
tip of the needle,” Dr. Nazarian said.
Tenotomy was then followed with injections of 40 mg of triamcinolone acetonide. Dr. Nazarian noted that he stopped
the drug in 2002 because the team had
found no difference between the steroid
and nonsteroid cohorts in their study. This
step ultimately created a second, nonsteroid group which Dr. Nazarian reported separately.
The procedure is complete and the needle removed “when it looks like we’ve
treated the entire abnormal tendon, and

C H I C A G O — The pain of common extensor tendinosis, or backhand tennis elbow, can be alleviated with ultrasoundguided percutaneous needle tenotomy,
according to Dr. Levon N. Nazarian of
Thomas Jefferson University Hospital in
Philadelphia.
“This is a safe and effective procedure
for lateral elbow tendinosis and may represent a viable alternative to surgery in patients who have failed conservative management,” Dr. Nazarian said at the annual
meeting of the Radiological Society of
North America.
Also known as
lateral epicondylitis,
this chronic repetitive injury leads to
degeneration of the
common extensor
tendon in the elbow
and scant—if any—
inflammation,
which is why this
problem of tendinosis should not be
confused with tendonitis, Dr. Nazarian explained. When
