Long Forearm Splints are routinely used to help freeze and support forearm and elbow injuries. Splints have a number of benefits as compared to the use of a cast. To begin, a splint merely covers half of the circumference of the arm to allow for swelling variations. In a variety of scenarios, long forearm splints are used to immobilize both bone and soft tissue injuries in the upper extremities. With this type of splint, the elbow and wrist are immobilized. Rubber is used in Long Forearm Splints, and it could be used by everyone.
