Abstract: A splint member comprises a rigid, elongated tube and a cushioning sleeve removably mounted to its exterior. The tube has an externally threaded and an internally threaded section, located on opposing ends of the tube. These threaded sections allow a splint member to be connected to another splint member, in an end to end fashion. The tube has a second internally threaded section, located at its midpoint. The second internally threaded section, allows for a splint member to be connected at a right angle to another splint member. The splint member may be fitted with connectors that allow it to be adjacently joined along its long axis to another splint member. By combining splint members, to increase length or width, a care giver can selectively assemble multiple types of devices for the temporary treatment of skeletal injuries.
