An intramedullary nail (20) and related method for fixing a fracture in a long bone. The nail (20) comprises an elongate member (22) having a longitudinal axis (54), a proximal end section (32), a distal end section (34) and a solid central section (24) extending between the proximal and distal end sections (32, 34). The proximal and distal end sections (32, 34) respectively include proximal and distal fastener receiving areas (28, 30) of greater cross section dimensions than the central section (24). Each fastener receiving area (28, 30) includes at least one hole (50, 52) extending transverse to the longitudinal axis for receiving a cross fastener (110) adapted to secure to the bone on opposite sides of the elongate member (22). The proximal and distal end sections (32, 34) thereby provide rigid anchoring locations relative to the central section (24) and the central section provides flexibility to promote healing of the fracture.
L'invention porte sur une broche intramédulaire (20) et le procédé associé de réduction d'une fracture dans un os long. Ladite broche (20) consiste en un élément allongé (22) présentant un axe longitudinal (54), une extrémité proximale (32), une extrémité distale (34), et une portion centrale pleine (24) reliant les extrémités (32, 34). Lesdites extrémités (32, 34) comportent respectivement des zones recevant des fixations proximale et distale (28, 30) de plus forte section transversale que la portion centrale (24) et dont chacune (28, 30) présente au moins un trou (50, 52) normal à l'axe longitudinal destiné à recevoir une fixation transversale (110) permettant de saisir l'os sur les côtés opposés de l'élément allongé (22). Les extrémités proximale et distale (32, 34) constituent donc des sites rigides d'ancrage à la portion centrale (24) dont la flexibilité favorise la guérison de la fracture.
