The jig includes bearing portions capable of engaging, only on the anatomical bone structure of the patient, with the front and rear edges of the socket, said portions having temporary positioning and attaching arrangements defining contact surfaces engaging with said front and rear edges, and said portions being formed from an area for connecting with a gripping sleeve arranged to act as a bore guide, wherein the positioning and orientation of the sleeve are predetermined relative to a three-dimensional coordinate system specific to the scapula and resulting from a peroperative plan translated via a bore axis defined by a vector and an origin that is the center of the socket, wherein both the vector and the origin give said orientation to the customized placement jig.
