Abstract: The systems and methods provide or use a brace for patient's limb that includes, among other things, a non-inflatable, rigid, lower housing for supporting the sole of a patient's foot, and an inflatable load-bearing upper housing that is affixed to the lower housing. The brace may be adjustable and configured to be fitted to patients having limbs of differing sizes, to allow the patient to obtain a more closely fitted brace.

Abstract: A brace worn by a user has side shell portions disposed in or on the lateral and medial sides portions of the brace to support the medial and lateral sides of the user's ankle. The shell may include a connecting center portion that extends under the foot of the user and couples the medial and lateral side shell portions. In certain embodiments, the connecting portion includes a plurality of flexible fingers oriented substantially towards the user's toes for yielding to the movement of the user's foot while maintaining the stability and orientation of the lateral and medial supports with respect to the user's ankle.
