A therapeutic orthopedic device is described. The orthopedic device serves to restrain and limit movement of a human arm and shoulder. The device comprises a torso pillow, a padded forearm support attached to the pillow and a shoulder strap that traverses the clavicle region of the opposite shoulder. The pillow is positioned to rest against the torso of a user and the strap is positioned over the opposite shoulder. The forearm support acts as a shelf upon which the user's forearm may rest in a natural position. Flexible straps extend from the forearm support, over the user's forearm, and engage with the pillow to secure the forearm.
