Abstract
A brace has a number of flexible compression bags filled with liquid disposed around the injured body part. The liquid is pressurized by a pump, which may be driven by muscle contracting or weight-bearing activities. The pump may provide a dynamic, oscillatory pressure, or a constant pressure, which pressure may be equal to the normal resting liquid pressure in the injured limb. The bags are segmented with valves allowing the liquid to flow in a controlled manner through the bags. The bags may be containing bags, or may be selectively placed to create pressures to resist specific injury effects and potential deformations when healing.
