one-and-a-half spica cast, an orthopedic cast that covers the trunk cranially to the nipple line, one leg caudally as far as the toes, and the other leg caudally as far as the knee. For stability, there is often a diagonal crossbar to connect the parts of the cast encasing the legs. This type of cast is used for immobilization during healing of a fractured femur or after surgical hip repair or for correction and maintenance of the correction of a hip deformity. Compare bilateral long-leg spica cast, unilateral long-leg spica cast.
