    摘要： A fastener for the treatment of fractures and the materials for production thereof. The fastener having a head with a contact portion for an installation tool and an attaching part having a treaded portion. The threads of the threaded portion are 5 to 20 % of the height of the outer diameter of the thread. The material for producing the fastener is a blend containing a biodegradable base material and one or more copolymer additives so that at room temperature the ductility of the blend is substantially higher than that of the pure base material. The base material may be a biodegradable polymer and/or a copolymer.

    摘要： An instrument for shaping a mouth part of a drilled tunnel provided in a bone. The instrument includes a shaft having a longitudinal axis and a first and a second end. The first end of the shaft is provided with a projection, which includes a blade for shaping the mouth part of the drilled tunnel when the instrument is turned around the longitudinal axis of the shaft. The instrument is asymmetric at an intersecting surface perpendicular to the longitudinal axis and intersecting with the blade, the instrument thus shaping the surfaces surrounding the first end only substantially within an area corresponding with a turning angle of such a turning movement.

    摘要： A polymer lactide is prepared by the polymerization of meso-3,6-dimethyl-1,4-dioxane-2,5-dione or mesodilactide and, if desired, other monomers. The mesolactide monomer has preferably a free acid content of less than 1 meq/kg dilactide and is then polymerized in a manner known per se. The compositions containing polymesolactide obtained according to this process do not posess the typical characteristics of poly-DL-lactide, poly-D-lactide or poly-L-lactide. A shorter degradation time of a substrate based on the present polymer is unofficial for several purposes. The present polymers have a good biocompatibility and are thus suited for bone plates, clamps and sutures and controlled release of biologically active compounds. The present polylactides and/or copolymers thereof have the benefit of a good biodegradability, biocompatibility, non-toxicity and non-mutagenicity.
