摘要： The device serves for the treatment of fractures of the femur and comprises an intra-medullary pin (1) with a central longitudinal axis (2), a front piece (3), which may be introduced into the medullary channel of the femur, a rear piece (4) and a hole (5), going through the rear piece (4) at an angle to the longitudinal axis (2) with a non-circular cross-section (6). The device further comprises a sliding sleeve (10) which may be introduced through the hole (5) with non-circular cross-section, having a front end (11), a rear end (12), a central longitudinal drilling (13), an outer sleeve surface (14), an inner sleeve surface (15) and a longitudinal axis (16). Furthermore, the device comprises a longitudinal bone fixation element (20) with a longitudinal axis (21), a head piece (22) with fixation means (23), which may be brought into engagement with the femur head on use and a shaft (24), which may be introduced co-axially into the sliding sleeve (10), whereby the outer sleeve surface (14) of the sliding sleeve (10) has a non-circular cross-section (17), at least in a partial region. The inner sleeve surface (5) of the sliding sleeve (10) comprises a round cross-section (18) and fixation means (30) are provided for the selective blocking of the rotation of the longitudinal bone fixation element (20) in the sliding sleeve (10).

摘要： The invention relates to a device for treating femoral fractures, comprising A): an intramedullary nail (1) having a central longitudinal axis (2) and a passage (5), which passes through the rear portion (4) of the nail (1) diagonal to the longitudinal axis (2) and which has a noncircular cross-section (6); B) a slide bush (10) that can be guided through the noncircular passage (5); C) a longitudinal bone fixation element (20) having a head part (22) with fixation means (23) that, when in use, can be brought into engagement with the femoral head, and with a shank (24) that can be coaxially inserted into the slide bush (10), whereby; D) the outer lateral surface (14) of the slide bush (10) has a noncircular cross-section (17) at least in one partial area; E) the inner lateral surface (15) of the slide bush (10) has a noncircular cross-section (38) at least in one partial area; F) the shank (24) is rotationally mounted in the longitudinal boring (13) of the slide bush (10), and; G) blocking means (30) are placed at the free end (27) of the shank (24) so that the rotation of the longitudinal bone fixation element (20) can be either blocked in a positive manner or deblocked relative to the slide bush (10).
