The Leg Brace is designed to provide functional management of stress fractures and the graduated management of certain stable fractures of the lower leg. The Leg Brace features anatomically designed shells lined with the patented Duplex� aircell system. This exclusive system incorporates two pre-inflated overlapping aircells, distal and proximal, that provide support and produce graduated compression during ambulation. The compression promotes efficient edema reduction and helps accelerate rehabilitation.
