Bradford split frame [Edward H. Bradford, American surgeon, 1848–1926] , a rectangular metal orthopedic device covered with two separate pieces of canvas fastened at both ends of the frame. Used especially in pediatrics to aid in the immobilization of children in traction, it is divided in the middle by a large opening designed to accommodate the excretory functions of an incontinent patient in a hip spica cast. The division also allows the upper and lower extremities of the patient to be elevated separately and the cast to be kept clean and dry.
