All patients who are immobile for a length of time will develop a contracture (stiff joint), whether their ankle is in a neutral position or plantar flexed. The Heel Keeper allows the patient to safely walk and the ankle joint to be moved through the range of motion while in bed which helps prevent contracture in awake patients. If a patient is comatose or completely immobile they will develop a contracture in whatever position the ankle is in. Our soon-to-be released Heel Keeper AFO will provide protection against developing a contracture and can be used for treatment.
