Abstract
L'invention concerne un clou intramédullaire chirurgical (10) destiné à stabiliser des fractures condyliennes ou supracondyliennes du fémur. Il comprend un dispositif cruciforme composé de deux boulons (21, 26) de blocage à croisement oblique, de façon que chaque condyle du fémur soit maintenu par l'un d'entre eux. Les deux condyles du fémur sont ainsi stabilisés par rapport au corps du fémur. Ces boulons sont orientés de façon à traverser la masse extra-articulaire principale de chaque condyle. D'autres perforations pré-percées (30, 35) sont prévues pour l'insertion de boulons de blocage proximaux destinés à stabiliser le clou par rapport au corps du fémur. Ce clou est conçu pour une insertion rétrograde, de l'extrémité distale à l'extrémité proximale, dans le canal intramédullaire du fémur. L'insertion des boulons de verrouillage peut être facilitée par l'utilisation d'un gabarit de couplage temporaire solidement fixé à l'extrémité distale du clou (11). Des clous de conception similaire permettent de stabiliser des fractures équivalentes de l'humérus.
