The mechanical trauma protection device is an arching bar which covers over an open splint to protect and area from mechanical trauma. It can be fabricated from plastic, metal or other material. The arching bar attaches to a splint, brace or other device to prevent contact. It can be made integral to a splint such as a protective posture hand splint by forming the material into an arch which extends from the index finger ray to the wrist. This allows the use of the bar as a handle (preventing patient handling/contact injuries) and to serve as a frame for further barriers.
