An osteotomy guide assembly for femoral neck osteotomy includes a saddle locator assembly and a saw guide attachment. The saddle locator assembly includes a barrel-shaped locating device that locates the saddle region of the proximal femur. The barrel further includes a transverse support bar extending from the barrel. The barrel is positioned over an intramedullary shaft which is temporarily positioned in and extends from the medullary canal of the femur. A saw guide is used in conjunction with the saddle locator assembly. The saw guide is attached to the support bar by a single locking means which provides for positional adjustment of the saw guide relative to the support bar in two directions, including adjustment in the anterior-posterior direction along the transverse support bar and axially along the femur via a post which extends from the saw guide.
Assemblage-guide pour l'ostéotomie du col fémoral comprenant un assemblage de positionnement de la selle et un guide de scie. L'assemblage de positionnement comprend un dispositif de localisation en forme de baril qui permet de localiser la région de la selle du fémur proximal. Ce baril est muni d'une barre de soutien transversale. Le baril est placé sur une tige intramédullaire temporairement placée dans le canal médullaire du fémur et en sortant. Le guide de scie, utilisé conjointement avec l'assemblage de positionnement, est fixé à la barre de soutien par un seul dispositif de verrouillage qui permet d'en ajuster la position dans deux directions par rapport à la barre de soutien, notamment d'ajuster la direction antéro-postérieure le long de la barre de soutien transversale, et le long de l'axe du fémur via un poteau sortant du guide de scie.
