Osteonecrosis of the
Hip Osteonecrosis

00:00:05.856 --> 00:00:08.386 A:middle
of the hip is a disease
that happens when blood flow

00:00:08.386 --> 00:00:10.556 A:middle
to the bones in the
hip joint is cut off.

00:00:10.556 --> 00:00:13.236 A:middle
This causes the bone to die.

00:00:13.236 --> 00:00:16.246 A:middle
And over time, the
damaged joint may collapse.

00:00:16.246 --> 00:00:19.586 A:middle
The cause of osteonecrosis
is not always known,

00:00:19.586 --> 00:00:21.946 A:middle
but certain things
can increase your risk

00:00:21.946 --> 00:00:24.686 A:middle
of getting osteonecrosis
of the hip.

00:00:24.686 --> 00:00:27.846 A:middle
These include: Having a
past injury to the hip

00:00:27.846 --> 00:00:31.926 A:middle
such as a fracture Using
corticosteroids for a long time.

00:00:31.926 --> 00:00:34.586 A:middle
You might take these
medicines for conditions

00:00:34.586 --> 00:00:36.936 A:middle
like asthma or arthritis.

00:00:36.936 --> 00:00:41.126 A:middle
Having chemotherapy or radiation
treatment Drinking too much

00:00:41.126 --> 00:00:45.116 A:middle
alcohol over a long time,
or Having another disease

00:00:45.116 --> 00:00:47.846 A:middle
such as Gaucher disease,
pancreatitis,

00:00:48.116 --> 00:00:52.056 A:middle
or sickle cell anemia
Osteonecrosis can cause severe

00:00:52.116 --> 00:00:54.346 A:middle
pain in your hip or groin.

00:00:54.476 --> 00:00:56.666 A:middle
You may not be able to
move your hip very much

00:00:56.666 --> 00:00:57.686 A:middle
because of the pain.

00:00:57.896 --> 00:01:00.606 A:middle
Pain is worse when you
put weight on the joint.

00:01:00.606 --> 00:01:04.506 A:middle
Because of the joint pain,
the disease can feel a lot

00:01:04.506 --> 00:01:06.566 A:middle
like arthritis, but it is not.

00:01:07.336 --> 00:01:09.446 A:middle
Arthritis is caused
by wear and tear

00:01:09.446 --> 00:01:11.566 A:middle
on a joint, or by inflammation.

00:01:12.136 --> 00:01:15.636 A:middle
Osteonecrosis is also
called avascular necrosis.

00:01:16.246 --> 00:01:18.506 A:middle
It is most common in the hip.

00:01:18.536 --> 00:01:21.186 A:middle
But it can occur in other
joints in your body, too.

00:01:23.326 --> 00:01:29.186 A:middle
Diagnosis Your doctor can
usually diagnose osteonecrosis

00:01:29.186 --> 00:01:30.426 A:middle
of the hip with an X-ray.

00:01:30.546 --> 00:01:34.656 A:middle
In some cases, you may
need an MRI, a bone scan,

00:01:34.826 --> 00:01:36.086 A:middle
or another imaging test.

00:01:36.756 --> 00:01:38.836 A:middle
You may also need a bone biopsy.

00:01:39.576 --> 00:01:42.826 A:middle
The doctor will remove tissue
from the affected bone and send

00:01:42.826 --> 00:01:46.156 A:middle
to the lab to be looked at.

00:01:46.156 --> 00:01:51.336 A:middle
Treatment In early stages of
the disease, you may get relief

00:01:51.386 --> 00:01:53.806 A:middle
from medicines that
reduce pain and swelling.

00:01:54.206 --> 00:01:56.446 A:middle
You may need to use
a cane, crutches,

00:01:56.526 --> 00:01:59.426 A:middle
or a walker to help take
the weight off your hip.

00:02:00.196 --> 00:02:02.046 A:middle
Eventually, you will
probably need

00:02:02.076 --> 00:02:03.806 A:middle
to have surgery on
your hip joint.

00:02:04.556 --> 00:02:06.986 A:middle
This is to help keep the
joint from breaking down.

00:02:07.836 --> 00:02:08.816 A:middle
One type of surgery

00:02:08.886 --> 00:02:12.266 A:middle
for osteonecrosis is called
core decompression surgery.

00:02:13.006 --> 00:02:15.816 A:middle
In this procedure, the
surgeon drills one large hole

00:02:15.816 --> 00:02:17.796 A:middle
or several smaller
holes into the bone

00:02:18.086 --> 00:02:20.276 A:middle
to help blood flow
better through the joint.

00:02:21.016 --> 00:02:23.336 A:middle
Another type of surgery
is a bone graft.

00:02:24.276 --> 00:02:27.116 A:middle
In a bone graft, the
surgeon takes healthy bone

00:02:27.116 --> 00:02:29.166 A:middle
and the blood vessels
that supply it

00:02:29.296 --> 00:02:31.646 A:middle
from elsewhere in your body.

00:02:31.646 --> 00:02:34.196 A:middle
The surgeon transplants
them into the hip joint.

00:02:34.196 --> 00:02:38.646 A:middle
The last option is a
total joint replacement.

00:02:38.646 --> 00:02:42.086 A:middle
In this procedure, the surgeon
replaces the diseased hip joint

00:02:42.206 --> 00:02:43.436 A:middle
with artificial parts.

00:02:43.436 --> 00:02:47.406 A:middle
Recovery from surgery to
treat osteonecrosis can take

00:02:47.406 --> 00:02:50.486 A:middle
several months.

00:02:50.486 --> 00:02:55.406 A:middle
Things to remember Osteonecrosis
of the hip is caused

00:02:55.406 --> 00:02:58.356 A:middle
by a problem with blood flow
to the bones in the hip joint.

00:02:58.356 --> 00:03:02.736 A:middle
At first, medicines may help
relieve pain, but eventually,

00:03:02.736 --> 00:03:04.816 A:middle
you'll probably need surgery.

00:03:04.816 --> 00:03:09.016 A:middle
Recovery from surgery to
treat osteonecrosis can take

00:03:09.066 --> 00:03:11.506 A:middle
several months.

00:03:11.506 --> 00:03:16.246 A:middle
What we have learned
Osteonecrosis is a form

00:03:16.246 --> 00:03:17.036 A:middle
of arthritis.

00:03:18.066 --> 00:03:19.306 A:middle
True or False?

00:03:19.466 --> 00:03:22.416 A:middle
The answer is false.

00:03:23.376 --> 00:03:25.476 A:middle
Although the symptoms
feel like arthritis,

00:03:25.846 --> 00:03:29.076 A:middle
osteonecrosis is caused by
poor blood flow to the bone.

00:03:29.846 --> 00:03:31.966 A:middle
Arthritis is a disease
of wear and tear,

00:03:32.376 --> 00:03:34.466 A:middle
or it involves inflammation
of the joint.

00:03:36.516 --> 00:03:38.596 A:middle
A total joint replacement
is one way

00:03:38.596 --> 00:03:40.436 A:middle
to treat osteonecrosis
of the hip.

00:03:41.576 --> 00:03:42.756 A:middle
True or False?

00:03:44.086 --> 00:03:45.466 A:middle
The answer is true.

00:03:46.506 --> 00:03:49.296 A:middle
Although medicine can help
relieve pain in the short term,

00:03:49.746 --> 00:03:51.906 A:middle
you will eventually
need a joint replacement

00:03:51.906 --> 00:03:53.226 A:middle
or another type of surgery.

00:03:55.366 --> 00:03:59.096 A:middle
Alcoholism or chronic alcohol
abuse can put you at risk

00:03:59.166 --> 00:04:00.816 A:middle
for osteonecrosis of the hip.

00:04:02.026 --> 00:04:03.336 A:middle
True or False?

00:04:05.026 --> 00:04:06.556 A:middle
The answer is true.

00:04:07.816 --> 00:04:10.956 A:middle
Drinking too much alcohol
can cause blood flow problems

00:04:10.956 --> 00:04:15.006 A:middle
to the bone.
