摘要： A device for bone fixation defining at least one through hole extending therethrough, the through hole including first and second through apertures separated from one another by a first resilient element deformable radially outward from the first aperture to expand the first aperture and contract the second aperture, the second aperture being sized and shaped to receive therein a bone fixation element, the second through aperture being smaller in size than the first through aperture, a periphery of the first through aperture comprising at least two substantially circular arcs B1 and B2 with respective radii R1 and R2 and respective centres Z1 and Z2 located at a distance X≧0 extending transversely to the resilient element whereby the ratio R1:R2 is in the range between 0.5 and 2.0.

摘要： 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.
