An implant system (10) for use in orthopaedic surgery for fixation of bone includes an intramedullary nail (12) and a coupling member (38). The intramedullary nail includes a proximal portion (18) defining a longitudinal axis (30). The proximal portion includes an axial bore (32) defining an axis (62) substantially parallel to the longitudinal axis of the proximal portion and a transverse bore (24) configured to receive a bone fastener (14). The coupling member includes a through hole (44) and is movably arranged within the axial bore of the proximal portion. Further, the coupling member includes a drive portion (40) and a bone fastener engagement portion (42). The drive portion is in one variant non-rotatably coupled to the bone fastener engagement portion. The bone fastener engagement portion is configured to engage the bone fastener penetrating the transverse bore. In one variant the engagement is realized via an extended contact region (52).
