Title
(EN) INTRA-MEDULLARY FIXATION DEVICE
(FR) DISPOSITIF DE FIXATION INTRAMÉDULLAIRE
Abstract
(EN)
An intra medullary fixation device (2) , comprising: a nail (4) which can be inserted into the intra medullary channel of a bone, the nail having a generally laterally extending bore (6) ; and an arm (8) which can be located so that it extends through the bore of the nail, along the neck of the bone when the device is implanted in the bone. The arm has a threaded portion (18) at one end for fixation into the head of the bone. The nail and arm between them provide a locking mechanism (10) to prevent rotation of the arm relative to the nail while allowing sliding of the arm through the bore. The locking mechanism is located on the lateral side of the nail and the distal side of the arm, relative to the bone.
(FR)
Dispositif de fixation intramédullaire (2) comportant : un clou (4) qui peut être introduit dans le canal intramédullaire d’un os, le clou ayant un alésage (6) qui s’étend généralement latéralement ; et un bras (8) qui peut être placé de façon à se prolonger au travers de l’alésage du clou, le long du col de l’os quand le dispositif est implanté dans l’os. Le bras a une partie filetée (18) à une extrémité pour sa fixation dans la tête de l’os. Le clou et le bras réalisent, à eux deux, un mécanisme de verrouillage (10) qui empêche la rotation du bras par rapport au clou tout en permettant le coulissement du bras au travers de l’alésage. Le mécanisme de verrouillage est placé sur le côté latéral du clou et sur le côté distal du bras, par rapport à l’os.
