Long-Term Effects of FHO Surgery in a Young Foster Dog

Femoral head ostectomy (FHO) removes the ball of the thigh bone, and scar tissue forms a false joint. Most dogs, especially smaller ones, return to normal or near-normal activity, though the operated leg is often a little less flexible and slightly less muscular than the other, and some dogs keep a mild limp.

FHO doesn't involve implants, so there's nothing to loosen or replace later. The main long-term needs are keeping him lean and well-muscled with regular exercise, which also protects his other joints. FHO is often done in young dogs, and most grow normally afterward, but the operated leg can end up slightly shorter or weaker, so ask the vet how his size and age may affect his long-term result. Ask the shelter's vet why the surgery was done, since an underlying condition such as hip dysplasia can also affect the other hip, and request his records and X-rays.
