Fix your broken bones the homemade way.
Once you’ve set the bone, you can make your own cast. All you need is a roll of toilet paper and a roll of duct tape. Wrap the wrist gently and generously in toilet paper until you have a firm but pliable soft cast. This might take a few dozen wraps. Don’t apply the duct tape to hairy arms or hairy anything! The removal would probably hurt worse than bone breaking itself. To make the sling, simply pull off a long piece of duct tape and apply the sticky side to the bottom of the cast and up the sides. When the underside is taped and the wrist is supported, fold the duct tape in half on itself. Do this on both sides.
