| 摘要 |
The invention relates to an intramedullary nail (1) comprising: A) a distal end for introducing into the medullary space, the section of the nail (1) facing the distal end (2) having a diameter D; B) a proximal end (3); C) a central longitudinal axis (4); and D) a plurality of transversal boreholes ( 5) having a borehole axis (6), said boreholes each defining a virtual borehole cylinder (8) with a cylinder axis (9) corresponding to the axis (6) of the defining transversal borehole (5); E) the borehole cylinders (8) of at least two transversal boreholes (5) penetrating each other. The cylinder axes (9) of both penetrating borehole cylinders (8) have no common point of intersection P on the longitudinal axis (4). In this way, there is an improved mechanical resistance compared to prior art, without enlarging the cross-section of the nail.
