A splint includes a first substantially flexible member having an inner surface and an outer surface. A second substantially flexible member has an inner surface and an outer surface, and is hingedly attached to the first substantially flexible member. An attachment strap is slidably attached to the outer surface of the first or the second substantially flexible member, and is configured for longitudinal movement relative to the first and second substantially flexible members. A substantially rigid slat is removably mounted relative to at least one of the first and second substantially flexible members.
