| Both fibreglass and plaster splints and casts use padding, usually cotton, as a protective layer next to the skin. The splint or cast must fit the shape of the injured arm or leg correctly to provide the best possible support. Generally, the joint above and below the fractured bone is also covered by the splint or cast. Frequently, a splint is applied to a fresh injury first and, as swelling subsides, a full cast may be used to replace the splint. Sometimes, it may be necessary to replace a cast as swelling decreases and the cast 'gets loose'. Often as a fracture heals, a splint may be applied again to allow easy removal for therapy. |
