An air splint of the type used for first aid for fracture was applied immediately following below-knee amputation in six patients. Used in place of a rigid plaster dressing for ten days before converting to a shrinker sock and temporary prosthesis, it allowed control of stump edema, adjustment of external pressure on demand, and inspection of the extremity and operative wound on short notice.
