My boyfriend has what is known as "complete complex syndactyly" (translates to complete webbing, from palm to fingertip, of the fingers. Additionally, he has fusion of bones at the edge of the fingernails.) The joined fingers are the middle finger and the ring finger on both hands. He is 24 yrs old and has no health issues due to this condition.

Now to the point of my question. He and I have been talking about marriage. As menial as it sounds, the fact that he can not wear a wedding band on the correct finger saddens him a bit (he's sentimental). Does anyone know of any type of rings that are out there that could accommodate him? A jeweler told me of "finger link shanks" but after investigating them, it looks like they are simply adjustable rings. Thanks in advance for any advice or knowledge!
