Legg Perthes Disease

Legg Perthes disease affects the hip joint and ultimately causes arthritis and inflammation. The pain inflicted from this disease can be debilitating, and immobility is common. The disease starts when the head of the femur bone slowly begins to lose blood supply, eventually causing the head to die off. This portion of the bone collapses (in an X-ray you can see the femur head is far less dense than normal bone), and the surrounding cartilage cracks and warps.

There is no known cause of Legg Perthes disease, but it typically occurs in miniature, toy, and small breeds within their first year of living. If your pet exhibits any of the following symptoms, feel free to contact our office to schedule a treatment evaluation.

Symptoms of Legg Perthes Disease:

  • Clicking sound coming from hip joint. 
  • Lameness in hind leg(s). 
  • Limping. 
  • Reluctant to stand up, play, or jump. 
  • Thinning of thigh muscles. 
  • Weakness.

Diagnosing and treating Legg Perthes disease

Diagnosing Legg Perthes is not complicated, but some symptoms can mirror other degenerative hind leg diseases such as hip dysplasia and patellar luxation. During your pet’s appointment, the veterinarian will take radiographs that can help distinguish which disease your pet is suffering from.

In treating Legg Perthes, surgery is the method of choice for most veterinarians. Femoral head and neck ostectomy (FHO) is the most common and most successful surgical procedure for this particular disease. During this procedure, the veterinarian will remove the femur head, and in more severe cases, the neck of the femur bone as well. After healing, a pet’s body repairs itself to create a new joint of fibrous tissue and scar tissue, filling in the ball-and-socket joint area where the femur head once was. After the pet has had weeks to rest and allowed this scar tissue to build up, physical therapy rehabilitation is started to extend range-of-motion through hydrotherapy and other non-weight bearing activities. Also, weight management becomes extremely critical to prevent putting added stress on the hip joints. For pets that are genetically inclined to obesity, a nutrition plan might be implemented. The FHO surgery is often very successful in preventing further pain, improving range of motion, and increasing activity levels.

If you have any questions about treatment for Legg Perthes disease, please contact our office.

We took our 5 month old puppy in to get neutered today and had a great experience. They educate you on expenses without making you feel guilty if you decide against extra options. We were able to pick him up 5 hours after dropping him off which was also amazing. Would highly recommend to anyone looking for a vet.

Dr. Genova has been my 4 legged daughter's doctor for her whole life (10 years). He is very personable, informative and kind. I seriously cannot say enough positive things about him.. Why else would I trust him to take care of my baby girl?

The rest of the staff is also very kind. Most of them have changed throughout the years but one thing that hasn't is that you can immediately tell how much they all love animals.

This is definitely one of this places that I wish I could give more than 5 stars to.

We had our first experience at Village at Main Veterinary Hospital today and I couldn't wait to write a review because of how pleased I was with the entire staff and environment. I arrived way early for my appointment but they took me anyway since it was open with no problem at all. As soon as we walked in the door my puppy and I were greeted with smiles and even staff that didn't run the counter came out and greeted and loved on my puppy as well which really put her at ease. Every staff member acknowledged our presence at some point. We were taken back to an exam room and we saw Dr. Tran who was warm and loving toward my puppy, she really took her time and you could easily see that she loves what she does. Dr. Tran covered all of my questions I had planned to ask as well as asked if I had any others. I would highly recommend this clinic to anybody who has had a bad experience at another clinic because it will totally make up for it as it did in our case. Thank you so much again for making us feel right at home and loving what you guys do, I will continue to drive 30 minutes just to have my pooch continue to see you guys :)
