Title
(EN) CANNULATED MODULAR INTRAMEDULLARY NAIL
(FR) CLOU INTRAMEDULLAIRE MODULAIRE CANNELE
Abstract
(EN)
A modular intramedullary nail includes three nail components connectable end to end. The components are a proximal component (11), a curved, elongated central nail component (12), and a distal nail component (13). An open ended longitudinal bore extends through each nail component. The nail components are connected by corresponding conical projecting (31) and conical socket (27) end portions that fit together and are secured by impact. The connecting end portions have corresponding tooled flat portions adjacent the conical portions to make the connections self orienting. The tool flat portions align upon assembly to prevent rotation between the components and to ensure that the components are radially aligned. A cannulated, threaded fastener (14) provides additional fixation between the components by extending through the longitudinal bore of the three sections. A proximal enlarged head portion (15) of the fastener engages the proximal nail component, while a distal threaded section (18) of the fastener engages corresponding internal threads in the bore of the distal nail component.
(FR)
Un clou intramédullaire modulaire comprend trois éléments de clou pouvant être reliés bout à bout. Les éléments sont un élément proximal (11), un élément central allongé, incurvé (12) et un élément distal (13). Un alésage longitudinal dont l'extrémité est ouverte s'étend à travers chaque élément du clou. Les éléments sont reliés par des parties d'extrémités formant manchon conique (27) et à projection conique (31) correspondantes qui s'emboîtent et sont fixées par impact. Les parties d'extrémité de raccordement comprennent des parties plates cannelées adjacentes aux parties coniques pour assurer l'auto-orientation du raccordement. Les parties plates cannelées s'alignent lors de l'assemblage pour éviter la rotation entre les éléments et assurer leur alignement radial. Un élément de raccordement fileté, cannelé (14) assure une fixation supplémentaire entre les éléments en s'étendant dans l'alésage longitudinal des trois sections. Une partie de tête agrandie proximale (15) de l'élément de raccordement se met en prise avec l'élément proximal, tandis qu'une section filetée distale (18) de l'élément de raccordement se met en prise avec des filetages internes correspondants dans l'alésage de l'élément distal du clou.
