The final shape of a heat-recoverable orthopedic cast (1) is changed by a shaping member (4) which modifies the forces exerted on selected parts of the cast. The cast (1) includes an elastically deformed support (11, 12, 13) and a solid casting composition which maintains the support in its elastically deformed condition. When the cast is heated, the casting composition softens, releasing the elastic recovery forces of the support. The shaping member modifies the elastic recovery forces and/or external forces which are applied to the softened cast to change its shape, for example to bend a generally tubular cast such as a short leg walking cast.
