Femoral Head and Neck Ostectomy (FHO/FHNE)

What is a Femoral Head and Neck Ostectomy?

The hip is a ball and socket joint, with the femoral head (the upper part of the leg) being the ball and the acetabulum (a portion of the pelvis) comprising the socket. Femoral head and neck ostectomy is a surgical procedure in which we remove the ball portion and the attachment (neck) portion from the rest of the femur, which in essence removes the hip joint. The body forms a ‘new hip’ in the months following surgery. But unlike the normal contact of bone and cartilage, the new hip is a collection of scar tissue with additional support from the surrounding muscles and joint capsule.

FHO is a surgical treatment for hip disorders such as a fractured hip, hip dysplasia, hip luxation, and Legg-Calve-Perthes Disease in small dogs (less than 50 lbs) and cats. These animals are usually too small for the smallest hip replacement available for animals.
