Abstract

Improved orthepedic apparatus in the form of a generally U-shaped stirrup member having a base portion and a pair of opposed sidewall portions hinged to the base portion. A pair of air-inflatable liners or airbags are disposed interiorly of the stirrup member in a juxtaposed, substantially coextensive relation to the sidewall portions, respectively. Fastener straps are provided to maintain the sidewall portions of the stirrup snuggly fitted about the lower extremity. A resilient, compressible filler member, porous and permeable to air, is disposed interiorly of each airbag to serve the dual function of pre-inflating the airbag prior to the stirrup member being fitted about the lower extremity, and simultaneously providing a cushioning member between the stirrup member and the lower extremity. Value means are also provided on each airbag to facilitate further inflation of that airbag or reduction of internal air pressure at elevated altitudes.
