Methods and systems include a patient specific instrument for installing a glenosphere within a joint. For example, a method for implanting a glenosphere includes installing first and second pins in a glenoid cavity using a patient specific instrument that sets a distance between the guide pins, installing an implant at the location of the second guide pin, and guiding a glenosphere onto the implant using a helper connected to the first pin. In another example, a glenosphere helper includes a cup shaped body having an interior surface for engaging at least a portion of an outer surface of the glenosphere, and a flange extending from the cup to receive a guide pin at a point, the flange extending from the cup shaped body such that the point is positioned outside a periphery of the glenosphere.
