1. An orthopedic walker boot comprising:
- a substantially rigid external shell configured to receive a lower limb of a wearer, wherein said external shell includes an inner platform having an outer perimeter sized in substantial correspondence with the outer perimeter of the sole of the foot on the lower limb such that said outer perimeter of said inner platform substantially encircles the outer perimeter of the sole of the foot when the lower limb is received in said external shell and further wherein said inner platform is substantially horizontally aligned when the wearer is standing with the lower limb received in said external shell; and
a substantially rigid heel plate selectively transitionable between a detached condition and an attached condition with respect to said external shell, wherein said external shell has an open-heel configuration when said heel plate is in said detached condition and said external shell has a closed-heel configuration when said heel plate is in said attached condition and further wherein said heel plate in said attached condition is substantially vertically aligned perpendicular to said inner platform when the wearer is standing with the lower limb received in said external shell and said heel plate extends posteriorly around said external shell in substantially continuous correspondence with a posterior edge of said outer perimeter of said internal platform such that said heel plate forms a substantially continuous shield around the vertical posterior face of the heel of the foot.
