An implant system for use in orthopaedic surgery for fixation of bone includes an intramedullary nail and a coupling unit. The intramedullary nail has a proximal portion defining a longitudinal axis and a transverse bore. The proximal portion includes a bore defining a first axis and a guiding structure defining a second axis, wherein the first axis and the second axis are substantially parallel to the longitudinal axis of the proximal portion of the intramedullary nail and are spaced apart from each other. The coupling unit is movably arranged within the proximal portion and includes a substantially cylindrical pin and a drive member with a through hole. The guiding structure is configured to slidably receive the substantially cylindrical pin, such that the pin can engage within a groove of a bone fastener configured to penetrate the transverse bore of the intramedullary nail.骨を固定するための整形外科手術用のインプラントシステムは、髄内釘および結合ユニットを含む。髄内釘は、内側と、外側と、長手軸を画定する近位部とを有する。近位部は、近位部の長手軸に対して略平行な第1の軸を画定する穴と、骨留め具を受け入れるように構成された横穴とを含む。結合ユニットは、近位部の穴内に移動可能に配置され、髄内釘の外側および内側のうちの一方または両方に1つ以上の骨留め具係合部材を含む。
