Sorry to hear your ham is so unwell, did the vet give any metacam for the pain? He is most likely in quite a lot of pain & that won’t help with him wanting to eat.
All you van really do is give soft foods, safe baby foods, porridge & soaked pellets, I would be careful using the syringe, if he’s able to eat he should take some soft food himself. If you don’t have pain relief for him have a word with the vet about that.
He is a really good age but sadly at that age his chances of recovery are less so keep him comfortable may be all you can do.
