A glenoid component for treatment of rotator cuff arthropathy includes attachment to the coracoid process by a pin or post imbedded into a hole formed in the coracoid process. The glenoid component preferably also has a keel for extending into the glenoid fossa and protrusions such as ridges cemented to the acromion process. This way, an attachment point is preferably provided in/on the coracoid process, the acromion process, and the glenoid fossa, and at least two of the attachment points include a protrusion extending into a hole/slot drilled or otherwise formed in the bone. A jig is used for guiding/drilling into the bone, wherein the jig has both a glenoid fossa drill guide and a coracoid drill guide. The coracoid drill guide includes structure that abuts against opposing sides of the base of the coracoid process to prevent rotation of the jig relative to the scapula.
