It is possible to receive a balanced load and at the same time to at least partially thicken the inner fixing member to strengthen the connection with the femur and to reduce the risk of the inner fixing member cutting the femoral head by femoral neck fracture A fracture fixture for treatment is provided. The central axis of the femoral neck (2) is offset from the central axis of the intramedullary nail (11) located in the medullary cavity of the femoral stem (5). Therefore, in order to bring the inner fixing member (12), such as a lag screw or the like, passing through the femoral neck (2) close to the central axis of the femoral neck (2), the rear end side of the inner fixing member (12) is fitted The central axis of the through hole (13) was offset with respect to the central axis of the intramedullary nail (11).バランスよく荷重を受けることができ、かつ、少なくとも部分的に内固定部材を太くすることにより、大腿骨との結合を強めるとともに、内固定部材が大腿骨頭を切り裂くリスクを低減できる大腿骨頚部骨折の治療用の骨折内固定具を提供する。大腿骨頚部(2)の中心軸は、大腿骨幹部(5)の髄腔に配置される髄内釘(11)の中心軸に対してずれている。そこで、大腿骨頚部(2)を挿通するラグスクリュー等の内固定部材(12)を、大腿骨頚部(2)の中心軸に近づけるため、内固定部材(12)の後端側を嵌合する貫通孔(13)の中心軸を髄内釘(11)の中心軸に対してオフセットさせた。
