No need to send DRS $10, I'll do it for $9. My kid had this surgery.
The hamate surgery is excise. It doesn't repair the bone but actually just removes the broken piece of bone. The area where it breaks is too small for the bone to heal properly, so they just take the hook part out, which is useless. It comes out and it looks like a baby molar.
The recovery has nothing to do with the bone healing, but is more nerve related as they usually have to move the nerve to get to the broken bone, and the nerve in play effects two of the fingers and radiates up the forearm. So the recovery is tissue healing and the nerve getting back to normal and the muscle recovery. I'm pretty sure my kid was swinging a bat 6 weeks later, but he wasn't really feeling good for 3-4 months.
He's done for a few months IMO.
