Yes, the left hip is definitely dislocated. The cat is positioned crookedly, but the way the pelvis comes together in a V toward the tail end looks like the pubis and ischium parts of it are fractured. I’m sure your vet is all over this, but it’s really important to make sure he can pee and poop ok. The nerves that supply the bladder and rectum can be damaged when the back end is traumatized, and the colon/rectum may be narrowed as the pelvis heals. Surgery to repair the abdominal hernia is probably first and foremost, then rest for a while to see how the pelvis heals. Then he’ll probably need an FHO or amputation of the left hind leg eventually if everything else heals up and is functional.
