First Claim
1. An aerating cast for supporting a limb, comprising:
- an outer shell;
a cushioning insert supported within said shell; and
a plurality of linearly extending passageways defined within said insert, at least one of a further plurality of exterior surface positioned recess rings defined in said insert and an additional plurality of radially extending breathing holes extending through a cross sectional thickness of said insert and communicating with said outer shell in order to introduce an airflow into said insert to relieve patient discomfort.

Abstract
A cast for supporting a limb includes a rigid outer shell, such as provided as first and second assembleable halves interconnected by a plurality of latches. An inner conforming foam insole is supported within the shell and is interconnected by pluralities of linearly extending passageways in combination with radially extending rings and which communicate with additional breathing holes extending through a cross sectional thickness of the insole for introducing an airflow for relieving patient discomfort. A toe attachable fan unit creates the airflow within the insole in communication with a plurality of vents positioned at upper terminating ends of each of the linear extending passageways. A plurality of airbags encircle the insole and are iteratively inflated and deflated to achieve a pulsing massage effect.
