Abstract

An improved apparatus and method for applying a total contact cast to a patient utilizes a kit of pre-packaged materials containing all of the items necessary. A uniquely designed padding strip pads the bony prominence on either side of the ankle, the top metatarsal area, and the crest of the shinbone in one unitary piece. Special cuts in the padding strip allow it to conform tightly to the bend between the foot and lower leg. The special cuts also allow the connected circular or elliptical flaps to also conform easily to the bony prominence of the ankle. Positioning the padding strip is simpler, easier, faster, and provides greater structural integrity to the overall cast. The unitary design helps prevent the padding strip from shifting when the cast is complete. An enlarged base portion of the walking heel eliminates the need for a separate wood platform for support.
