Abstract
An orthopedic device includes a posterior shell with ankle and foot receiving portions, and first and second wing portions forming an opening over a dorsal aspect of the posterior shell. A dorsal shell is contoured to substantially correspond to the opening of the posterior shell. The dorsal shell includes a proximal member and a distal member hingedly connected to the proximal member via a hinge mechanism. A pump assembly receiving opening is defined in the proximal member of the dorsal shell and a raised portion extends longitudinally along an exterior surface of the dorsal shell. A plurality of clearance holes are defined in the first and second wing portions. An inflatable bladder is disposed at least in the ankle receiving portion of the posterior shell. A pump assembly is inserted through the pump assembly receiving opening and is in fluid communication with the inflatable bladder.
