A drill guide apparatus (10) and method are provided for aligning and installing a transverse pin (138) through a tunnel (94) formed by a tunnel drill (12) in a bone (74, 76) to secure a ligament replacement (124) to the bone (74). The drill guide (10) includes an arm member (24) and a drill guide sleeve (36, 50) coupled to the arm member (24). The drill guide sleeve (36, 50) is formed to include a central bore (70) for guiding a drill (104) to form a transverse guide hole (108) in the bone (74) to guide insertion of the transverse pin (138) into the bone (74). The central bore (70) of the drill guide sleeve (36, 50) has an axis which is aligned to intersect the tunnel (94). The arm member (24) of the drill guide (10) is coupled to the tunnel drill (12) while the tunnel drill (12) is still in the bone (74, 76) to align the arm member (24) and drill guide sleeve (36, 50) at a desired anatomical location using the tunnel drill (12) in the bone (74, 76) as a reference.
Appareil de guidage de foret (10) et méthode pour aligner et poser une broche transversale (138) dans un tunnel (94) pratiqué dans un os (74, 76) au moyen d'un foret à tunnel (12) pour assujettir un ligament de remplacement (124) à l'os (74). L'appareil de guidage (10) comprend un bras (24) et une douille guide-foret (36, 50) raccordée au bras (24). La douille guide-foret (36, 50) est formée de manière à comporter un alésage central (70) pour guider un foret (104) servant à pratiquer un trou de guidage transversal (108) dans l'os (74) dans le but de guider l'introduction d'une broche transversale (138) dans l'os (74). L'alésage central (70) de la douille guide-foret (36, 50) a un axe qui est aligné de manière à croiser le tunnel (94). Le bras (24) de l'appareil de guidage (10) est raccordé au foret à tunnel (12) quand le foret à tunnel (12) est encore dans l'os (74, 76) de manière à aligner le bras (24) et la douille guide-foret (36, 50) en un point anatomique voulu en utilisant le foret à tunnel (12) dans l'os (74, 76) comme référence.
