A pressurized fluid cast for stabilizing a broken bone of a patient includes a sleeve having an inner wall and an outer wall with a fluid cavity between the inner and outer walls. The outer wall has at least one access port established therethrough. The sleeve is configured to be placed at a limb of a patient such that the inner wall circumscribes the limb and is disposed at least partially along the limb, with the fluid cavity and the outer wall being radially outward of the inner wall. The sleeve is adaptable to accommodate a particular patient injury and limb. Fluid is provided within the fluid cavity and is pressurized to a selected pressure to apply substantially uniform pressure at the limb of the patient. An outer protective shell may be provided at least partially around the sleeve to limit puncturing of the sleeve.
