Abstract: It is known that antibiotics, particularly gentamycine, are released with delay from plastic materials such as polymethacrylate and/or polyacrylate. Thereby, a steep initial decrease in concentration long periods of time. These antibiotic-containing synthetic materials have been used heretofore as bone cement, for the fastening of endoprostheses or in the, for instance of total endoprostheses of the hip or in the replacement of infected endoprostheses. To combat and prevent infection, the antibiotics are added prior to the polymerization of the synthetic material. The invention has the object to create. In accordance with the invention, it is the carrier (2) be shaped like a stick. The carrier (2) can also have the shape of a cylinder, with a central passage duct (4) provided in its longitudinal direction. The carrier (2) is provided with a plurality of radial openings (3), which communicate with a central passage duct (4).

Abstract: A splint or other body-support device adapted to fit around or along a body portion of a human or animal subject is formed with a closed compartment containing capsules or the like of two mutually reactive substances capable of hardening or foaming in situ to form a hardenable mass stabilizing the shape of the device. The device may comprise an envelope of a flexible material which may be kneaded or deformed to rupture the capsules and mix the reactive substances.
