radioulnar Fractures in Dogs and Cats

The radius and ulna are the two long bones of the forelimb between the elbow and the wrist (carpus).

In dogs and cats, these bones usually fracture together after trauma (falls, being hit by a car, getting a leg caught, rough play, etc.).

Small-breed dogs (especially toy breeds) and cats are often affected.

Some simple, stable fractures can heal in a splint or cast, but many radioulnar fractures are best treated surgically – especially in toy breeds, young animals, and any highly displaced or multiple piece (comminuted) fracture.

With proper repair and aftercare, most pets regain excellent limb function, but complications (like delayed healing or implant issues) do occur and are slightly more common in toy-breed radius/ulna fractures.
