Abstract
A femoral fracture treatment device including: an intramedullary pin (1) with a central longitudinal axis (2) and a passage (5) of non-circular cross-section (6) through a proximal portion (4) of the pin oblique to the longitudinal axis (2), a sliding sleeve (10) configured to pass through the non-circular passage (5), a longitudinal bone fixing element (20) having a head portion (22) with fixing means (23) for engaging the femoral head and a shaft (24) that may be coaxially introduced into the sliding sleeve (10). Both an external jacket surface (14) of the sliding sleeve (10) and an internal jacket surface (15) of the sliding sleeve (10) have non-circular cross-sections at least in a partial section. The shaft (24) is rotatably mounted in the longitudinal bore (13) of the sliding sleeve (10), and locking means are provided at the free end (27) of the shaft (24), such that rotation of the longitudinal bone fixing element (20) relative to the sliding sleeve (10) can be optionally locked or released.
