I have a completely knackered elbow and need to immobilise it and then protect it from the rigours of mountain biking. Have kind of worked out making the mould but laying the carbon fibre (or similar) is way out of my scope. It needs to be impact and abrasion resistant. From a quick read, perhaps a few layers of Diolen with Carbon top layers? Help keep the cost sensible. I'll probably line it with either sheepskin or foam Is that enough to get started?

By locking it rigid, you are much more likely to break your wrist, arm or dislocate your shoulder with much less of an impact due to removing virtually all damping in your arm and transferring the load to joints which don't move in that way. It's the same with LEAT braces used in moto, they reduced neck injuries but were causing more rib damage and lower back problems as they just transfer the load elsewhere. Because of that issue, I personally would stay away. I don't mean to be critical, I just wanted to point it out This is something I have considered, at great length. The problem is that the elbow joint is completely knackered. After 3 unsuccessful rebuilds there's no actual joint left. It's just the ends of 3 bones, some ligaments and screws. Plus half my tricep is missing too. Any load placed on the elbow runs a high risk of it falling apart which leaves me on a river of excrement in a native American craft with no means of propulsion. Short of giving up any MTB aspirations I don't know what else to do. Edited 11 Years Ago by identiti66
