BONE PLATE FOR THE FIXATION OF FRACTURES OF THE PROXIMAL HUMERUS

摘要

The invention relates to a bone plate, which is used for the fixation offractures of the proximal humerus. Said plate comprises a peduncular part (1),whose length is greater than its width x and a spoon-shaped part (2), whosewidth y is greater than the width x of the peduncular part (1). The peduncularpart (1) and the spoon-shaped part (2) have a common longitudinal central axis(3) and are interconnected by a transition zone (26). At least 2 screw holes(9, 10, 16, 17; 24) are configured in the peduncular part (1) and the spoon-shaped part (2) respectively. At least one of the screw holes (24) in thepeduncular part (1) has an at least partial internal thread (28) or partiallyspiralling key beds. At least one of the screw holes (9, 10, 16, 17) in thespoon-shaped part (2) has an internal thread (27) or partially spiralling keybeds. The lead of the internal thread (27; 28) or the partially spiralling keybeds ranges between 0.5 mm and 1.1 mm.
