RESORBABLE BONE PLATE

摘要

The bone plate of longitudinal shape has an upper surface (1), a curved lower surface (2) for contacting a bone, a plurality of conical through holes (3) connecting the upper surface (1) with the lower surface (2) for receiving bone screws, a central longitudinal axis (4) and consists of a resorbable material. The curved lower surface (2) has a radius of curvature R which is smaller than 10 mm. The ratio F/d of the total area F of the upper surface (1) including the surface area of the through holes (3) to the thickness d of the plate is in the range of 190 to 270 mm. The central part of the longitudinal plate has a generally constant width B whereas the width of the free ends of the longitudinal plate is narrowing to value b < 0,3 B. The resorbable bone plate overcomes the problems of adherence of soft-tissue. Its shape and function is optimized given the limitations of the properties of these materials.
