Abstract
A proximal humeral plate assembly can include a first plate, a coupler, a second plate, and a guide. The first plate can define a window and can have a first major surface adapted to conform to a native bone structure. The coupler can be formed on a second major surface of the first plate opposite the first major surface. The second plate can be adapted to engage the coupler, to cover the window, and to conform to the native bone structure. The second plate can include through holes adapted to receive bone screws. The guide can be adapted to engage the coupler and to guide at least one of a cutting tool and a dilation tool.
Claims23
A proximal humeral plate assembly comprising:
- a first plate defining a window, the first plate having a first major surface adapted to conform to a native bone structure;
- a coupler formed on a second major surface of the first plate opposite the first major surface;
- a second plate adapted to engage a mating surface on the coupler and to cover the window, the second plate including through holes adapted to receive bone screws, the second plate further adapted to conform to the native bone structure;
- and
- a guide adapted to engage the mating surface on the coupler and to guide at least one of a cutting tool and a dilation tool, the engagement between the guide and the mating surface on the coupler securing the guide to the first plate.
A proximal humeral plate assembly comprising:
- a first plate having a bone-engaging first surface and an opposed second surface, the first plate defining a window extending through the first and second surfaces, the bone-engaging first surface adapted to conform to a proximal humerus;
- a slide mechanism formed on the opposed second surface of the first plate;
- a second plate slidably engaged with a mating surface on the slide mechanism and supported by the first plate within the window, the second plate including through holes adapted to receive bone screws, the second plate further adapted to conform to the proximal humerus;
- and
- a guide adapted to engage the mating surface on the slide mechanism and to guide at least one of a cutting tool and a dilation tool, the engagement between the guide and the mating surface on the slide mechanism securing the guide to the first plate.
A proximal humeral plate assembly comprising:
- a first plate having a bone-engaging first surface and an opposed second surface, the first plate defining a window extending through the first and second surfaces, the bone-engaging first surface adapted to conform to a proximal humerus;
- a slide mechanism formed on the opposed second surface of the first plate;
- a second plate configured to slidably engage a mating surface on the slide mechanism, the second plate being sized to fit within the window and having an outer perimeter that conforms to an inner perimeter of the window such that the second plate covers the window when the second plate is placed within the window, the second plate including through holes adapted to receive bone screws, the second plate having a bone-engaging surface adapted to conform to the proximal humerus;
- and
- a guide adapted to engage the mating surface on the slide mechanism and to guide at least one of a cutting tool and a dilation tool, the engagement between the guide and the mating surface on the slide mechanism securing the guide to the first plate to prevent movement of the guide in a direction perpendicular to the first and second surfaces of the first plate.
