Disclosed herein are systems and methods for securing a glenoid baseplate to a resected glenoid cavity in a preoperatively planned position. Image information obtained from the glenoid cavity and surrounding scapula is analyzed to determine the location of optimal bone stock. A guide is designed based on the image information, the guide having a patient specific contact surface that contacts a surface of the bone in a preoperatively planned position. The guide is designed to have a cannulated portion including a specific length. A marking pin having at least one reference feature is drilled into the glenoid cavity. The length of the cannulated portion of the guide is based on a location of the at least one reference feature on an outer surface of the marking pin. A cannulated reamer guided by the marking pin is then used to resect the glenoid cavity until a stop surface of the cannulated reamer contacts an end of the marking pin.
A shoulder guide for resecting a preoperatively planned depth into bone comprising:
The shoulder guide of clam 8, wherein the guide shaft has a thickness defined by the inner and outer cylindrical walls.
A system for resecting a preoperatively planned depth into bone comprising:
The system claim of 18, wherein the internal wall is adjacent the receiving end of the cannulated portion having a protrusion extending outwardly therefrom.
