Abstract: A foot and leg splint has two main elements: a hard plastic shell portion and a flexible boot-like garment assembly which cushions the patient's foot and secures the foot to the shell. The shell has a back section shaped to provide comfortable support for the calf and lower leg of the patient. A first portion of the heel section extends straight downward from the back section with a flat back surface to prevent unwanted rocking or rotation of the patient's foot when the patient is in a prone position. A second portion of the heel section extends horizontally, perpendicular to the first section of the heel to form a squared-off heel and provide a flat surface for supporting the heel when the patient is standing or walking. A plantar section extends forward from the second heel portion and curves upward to support the arch of the patient's foot. A toe protector may be provided to extend forward beyond the plantar section.
