  • the sensor housing 500 allows a user to temporarily place the sensor pocket 510 in a known position such that a user can use a sensor and a tracking system (such as an electromagnetic or infra-red tracking system) to blindly target the at least one through hole 14, 1 14, 214, 314.
  • a tracking system such as an electromagnetic or infra-red tracking system
  • the targeting system can allow for projecting different trajectories.
  • the projected trajectory may allow for maximum bone purchase or to avoid a bone defect, such as bone defect 550.
  • Pre-operative image data such as x-ray, MRI, or CT, may be taken and coordinated with the tracking system to generate preferred or desired bone trajectories.
  • the sensor housing 500 has a tab 520 that engages a detent 530 in the glenoid component.
  • the tab 520 may be elastically biased to engage the detent 530.
  • the user prepares the scapula for the glenoid component, provisionally places the glenoid component, places the sensor housing/sensor onto the glenoid component, uses the tracking system to target the through hole, subcutaneously prepares the proximal and distal approach to the through hole, places a secondary fastener through the hole (if applicable) and locks the glenoid component in place.

Abstract

La présente invention concerne une prothèse glénoïdienne destinée à être implantée sur un os scapulaire. La prothèse glénoïdienne comporte une partie formant base présentant une surface d'appui articulaire configurée de façon à s'articuler contre une tête humérale ou un implant prothétique, une partie formant corps allongé s'étendant axialement à partir de la partie formant base et étant configurée de façon à se positionner à l'intérieur d'une cavité de l'os scapulaire, au moins un alésage traversant ou un trou débouchant s'étendant d'un côté à l'autre de la partie formant corps allongé et un élément de fixation étant configuré de façon à être placé dans l'os scapulaire et à traverser le trou débouchant ménagé dans la partie formant corps allongé afin de fixer ainsi la prothèse glénoïdienne à l'os scapulaire. La présente invention se rapporte également à un procédé d'implantation de la prothèse glénoïdienne sur un os scapulaire.
