Proximal humeral head

摘要

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.

1. A method of repairing a fracture in a proximal humerus, comprising:
fixing a first plate to the proximal humerus such that a fractured portion of the proximal humerus is anatomically aligned and accessible through a window formed in the first plate; engaging a guide with a coupler formed on the first plate; removing a lateral cortex of the proximal humerus using a cutting tool inserted through a hole in the guide and dilating a void in a cancellous portion of the proximal humerus; and filling the void by delivering a solid bone graft sized and shaped to fill the void through the hole in the guide.
