What is a femoral head ostectomy (FHO)?
Femoral head ostectomy is an orthopedic surgery to reduce discomfort caused by hip dysplasia and other diseases involving the femoral head. During an FHO, the head of the femur (the part of the femur that articulates with the pelvis) is removed. This allows the body to create a ‘false joint’ with scar tissue and the surrounding muscles, which provides appropriate stability for weight bearing. By removing the source of chronic pain—the contact between the femur and pelvis—pets experience more comfortable mobility and a better quality of life.
When is an FHO recommended?
Hip dysplasia is the most common reason for FHO surgery. While other surgical procedures provide greater hip function by replacing or correcting the joint, FHO is an acceptable alternative for smaller dogs who can’t be managed with medication alone.
Will my dog need an FHO on their other hip?
Although hip dysplasia is a bilateral condition, not all pets need a bilateral FHO. Your veterinarian will likely recommend an FHO for the more severe side first, then monitor their recovery to determine whether an additional procedure is needed.
What can I expect from my pet’s recovery?
Healing from FHO surgery is usually quicker than recovery from other orthopedic surgeries. Although you will need to support your pet’s mobility with a sling or harness for a few weeks, pets are encouraged to return to gentle exercise around two weeks after surgery. This promotes limb use and helps maintain muscle mass. Incision care includes close monitoring and the use of an e-collar until sutures are removed.
Pets who have FHO surgery must be kept at a healthy weight and avoid high-impact activity, such as running, jumping, or rough play. Following these guidelines and using pain medication as needed can help pets enjoy freedom from hip dysplasia pain.
