What is Femoral Head Osteotomy (FHO) Surgery?

Femoral Head Ostectomy — often called FHO surgery — is a well‑established procedure used to relieve hip pain in dogs. It is commonly recommended when the hip joint is damaged, diseased, or no longer functioning comfortably. This page offers an easy‑to‑understand overview for dog owners researching treatment options, supported by trusted veterinary sources.

What Is FHO Surgery?

FHO surgery involves removing the head and neck of the femur, which is the “ball” portion of the ball‑and‑socket hip joint. By removing this painful, damaged part of the bone, the body forms a false joint made of muscle and scar tissue, allowing dogs to move comfortably again.
This procedure is especially helpful when the natural hip joint can no longer glide smoothly due to injury or disease.

When Is FHO Recommended?

Veterinarians may recommend FHO surgery for dogs experiencing:
– Hip dysplasia
– Chronic hip arthritis
– Fractures of the femoral head or neck
– Legg‑Perthes disease
– Hip dislocation that cannot be corrected
– Severe trauma to the hip joint
These conditions can cause significant pain and reduced mobility. FHO offers a long‑term solution when other treatments are not effective.

How the Procedure Works

During surgery, the veterinarian:
– Removes the femoral head and neck
– Smooths the remaining bone
– Allows the body to form a comfortable pseudo‑joint over time
Although the false joint does not function exactly like a natural hip, most dogs regain excellent mobility and comfort, especially smaller breeds.

Benefits of FHO Surgery

– Reduces or eliminates chronic hip pain
– Improves mobility and quality of life
– Avoids the need for total hip replacement
– Works well for small to medium‑sized dogs
– Provides long‑term comfort with proper rehabilitation
Success rates are high, with many dogs returning to active, pain‑free lives after recovery.

What to Expect After Surgery

Recovery is an important part of achieving the best outcome. Most dogs:
– Go home the same or next day
– Begin controlled movement soon after surgery
– Benefit from physiotherapy or guided exercise
– Regain strength over several weeks to months
Rehabilitation is essential to prevent muscle loss and ensure the new joint functions well.
