An apparatus and method is provided for surgically securing bone parts, in particular for transsternal bilateral thoracotomy. The apparatus comprises a base piece (1) from which are protruding two posts (2 and 3) welded or attached thereto which are internally screw- threaded and adapted to receive screws (4 and 5). A plate (6) with holes (7 and 8) is adapted to be positioned over the posts (2 and 3) and secured relative to them by the screws (4 and 5). In the method of securing the bone parts using the apparatus, the posts (2 and 3) are inserted into holes (9 and 10) drilled in each respective bone part (11 and 12), so that the bone parts are held together with their sawn surfaces (13 and 14) mutually opposing. The plate (6) is positioned above the bone parts and screwed into position into the posts by the screws (4 and 5) through the holes and the plate (7 and 8).
L'invention décrit un dispositif et un procédé pour la fixation chirurgicale de parties osseuses, en particulier pour une thoracotomie trans-sternale bilatérale. Le dispositif comprend une pièce de base (1), sur laquelle font saillie deux pitons (2, 3) qui lui sont soudés ou fixés et comportent un filet intérieur permettant de recevoir des vis (4, 5). Une plaque (6) pourvue de trous (7, 8) peut être disposée sur les pitons (2, 3) et fixée par rapport à ceux-ci par les vis (4, 5). Dans le procédé de fixation des parties osseuses mettant en oeuvre ce dispositif, les pitons (2, 3) sont introduits dans des trous (9, 10) percés dans chaque partie osseuse (11, 12), de telle sorte que les parties osseuses soient maintenues ensemble avec leurs surfaces sciées (13, 14) face à face. La plaque (6) est placée au-dessus des parties osseuses et vissée en position dans les pitons par les vis (4, 5), à travers les trous et la plaque (7, 8).
