I broke my scaphoid (at the time, it was called a navicular) when I was 17. Being young and stupid, I ignored it b/c it didn't hurt that much and I thought it was a sprain. A year later, I smashed up my ankle pretty comprehensively on a CR500, and had a cast from toe to hip and I was on crutches. I told the ortho that my wrist hurt when I was using the crutches, and he said "get it X-Rayed, it's only $20 ... in 1982! I knew I was fucked when he came back into the office looking at the X-Ray, put his hand on my shoulder and said "Son, you have a problem." He explained that the navicular only gets blood flow from one side, and it simply won't heal left to its own devices. Plus, mine had degraded badly due to my abuse & neglect. He took a chunk out of my hip bone and grafted the two ends of the navicular together, and used 2 wire loops to hold them in contact. It did eventually heal, but it was a long time in a cast, iirc, 5 months (the ankle break was also a 6 month deal - I spent nearly a whole year in one or another cast.) There was also a micro-voltage bone growth stimulation thing going on with the wires - I clipped them to a box every night as I slept. When the cast came off, he grabbed the wires with pliers and pulled them out, which felt very oooogy. Anyway, long story short (too late!) yes, it still hurts. It hurts most if I lift heavy things over my head, or I bang it somehow - for example, I tried swinging a sledge hammer to break concrete a few years ago, and the shock *really* aggravated my wrist. Whenever the wrist gets pissed off, I do 2 things: #1, ICE IT, and the sooner the better! #2, I wear a wrist brace for 1~2 weeks. My favorite wrist brace is an older rollerblading wrist guard with the palm slider removed. SO.... regarding your situation, I think you're due for a second opinion, from a hand and wrist specialist. I don't think I'd be inclined to grant full and complete trust to the guy who installed a screw that came loose. I wouldn't be too excited about diving into a wrist fusion without a 2nd or even 3rd opinion, and I'd expect your insurance to support that. Also.... if it's not offered, be pretty insistent on getting PT after the cast comes off... IMHO, doing the PT *religiously* has a LOT to do with improving the outcome of any surgery.
