Femoral Head Ostectomy
This surgery is considered when the head of the femur bone is fractured or in cases of severe hip dysplasia: the leg remains functional and it stops the severe pain of the femur bone rubbing against the damaged hip socket.
This fancy sounding surgery is where we cut off the top inch or so of the femor bone so that it doesn't rub and grate on the hip bone.
Possible reasons for needing to do this are severe damage to the pelvis or femor head, typical of being hit by a car or for advanced cases of arthritis of the hip joint.
Unfortuately, this surgery is often chosen instead of the much superior option of fixing a femur fracture or dislocation because the owner doesn't want (or can't afford) to pay for fixing the fracture. Doing a femoral head removal costs a few hundred dollars. Having a orthopedic specialist fix a shattered leg with surgical plates can cost several thousand dollars. (A major reason to consider getting pet insurance) On the other hand, it's a better option than euthanasia.
This works especially well in mid size and smaller dogs. It often works well for large breed dogs too, but large breed dogs are more likely to have problems supporting their weight without an intact femur.
The surgery certainly relieves pets of the agony of having their leg bone grind into a damaged or chronically inflammed hip socket with every step. It's a little less likely to work out so well if both hip sockets are diseased, but's it's an option.
I do this surgery at our hospital, other vets like to refer to specialists for femor head removals.
Speaking of specialists...there are now physical therapists for pets in most states just like there are for human orthopedic patients.
The goal of the surgery is to form a "false joint", which leads to the formation of fibrous scar tissue around the rounded off bone end. The hardened muscle or scar tissue then acts like a pivot and support point for the bone.
Once the surgery site has had time to heal (3-8 weeks) there is usually very little pain and enough support to get around, which is our goal.
Some injuries are so bad that a femoral head removal is the only reasonable choice even if you are willing to pay several thousand dollars for a specialist.
But there are alternatives to removing the femor head:
There are techniques where the joint is "fused" or "stabilized".
There are several possible stabilization procedures, including pinning the femoral head to the hip socket, changing where the muscle attachment occurs to a different site on the femur, toggle pinning the femoral head and several other techniques that are above my pay grade.
Total hip replacement is another option.
If an alternative stabilization technique doesn't work, femoral head removal or ostectomy still remains an option. You do end up paying for two surgeries if one of the other stabilization methods fail but if it does work, the outcome is better for your dog.

Please Help:
I’ve written this web site mostly to share my love of my profession … taking care of the medical and behavioral problems of pets.
But I have three other desires:
To help animal lovers make sense out of the details and confusion of veterinary care
To encourage pet owners to be more responsible in the care of their pets
And I was really hoping to somehow raise money to keep our No Kill Pet Shelter running.
Our shelter is staffed 100% by volunteers and has been successful at finding homes for 200-300 pets a year that would otherwise be euthanized.
We take pets that are often filthy, full of parasites, suffering from diarrhea or colds or injuries. We clean them up, test and treat for heartworms, intestinal parasites, and leukemia.
Our pets are socialized, vaccinated, spayed or castrated, and treated with love and compassion until we can place them in a suitable home.
Please help us. Here’s How:
1. BiLo Grocery Stores generously donate 1% of all purchases to charities that they have approved.
We are on this approved list of 501c, tax deductible charities.
If you’ll print out the bar code below and take it to BiLo to scan; every time you use your BiLo Bonus Card, 1% of your purchase will be donated to our No Kill shelter.
This will help us a lot and not cost you a cent.
2. People from our community donate all sorts of craft items and home made pet clothes that we sell at our shelter.
And we also store a huge amount of garage sale items that people donate to us for our annual fund raising sale.
We are now selling these items on Ebay to raise money.
3. And finally, for those of you who are especially kind, we can now accept straight forward donations in a secure fashion using a credit card through PayPal.
