Small Dog With a Dislocated Hip After Being Hit by a Car: Is FHO the Right Choice?

Reader Question
my dog was just hit by a car (17 pound dog) and his hip was dislocated. There apppears to be no cracks in the dislocated hip but they tell me the ligament is torn so popping the hip back in will probably only result in it popping back out again due to no more ligament supporting it. They recommend chipping off the ball of the femer, saying it will create it's own capsule to support long term. Is this your recommendation?


Answer from Our Team

For a 17-pound dog, what your vet recommends is a common and sensible choice. Putting a dislocated hip back without surgery fails in many dogs, especially when the supporting ligament is torn, because the hip tends to pop out again. Femoral head ostectomy (FHO) removes the ball of the thigh bone, and scar tissue then forms a false joint. FHO usually works best in smaller, lighter dogs like yours.

Other options include surgically stabilizing the hip, for example with a toggle rod, or a total hip replacement at a specialist center. After FHO, early gentle exercise and physical therapy are important to rebuild muscle, and improvement can take 6 weeks or more. Because he was hit by a car, make sure he has also been checked for chest and internal injuries. A board-certified surgeon can give a second opinion if you'd like one.
