Abstract: This invention pertains to a plastic foot splint having a horizontal foot portion, a contoured upstanding leg portion and a heel portion connecting the foot and leg portions. The heel portion has a rearward side portion with an aperture therein to permit visual examination of the rearward portion of a patient's heel when the foot splint is mounted on one of the patient's feet. A stabilizer bar is pivotally secured by one of its ends to the leg portion. Ratchet teeth are located on one end of the stabilizer bar and on the leg portion at the location of its pivotal connection to the stabilizer bar to permit the stabilizer bar to be selectively held in a fixed position with respect to the leg portion.
