A marrow nail includes a nail 1 having a distal end 2, a proximal end 3, a longitudinal axis 4, and a slot 5 in the area of the proximal end, running transverse to the longitudinal axis 4. A cylindrical casing 10 is provided, which can be slid onto the proximal end 3 of marrow nail 1. This casing 10 exhibits a cylindrical axis 11 as well as at least two openings 12, 13 placed at opposite ends of the cylindrical cover 14. The casing 10 is formed in such a way that upon being slid onto marrow nail 1, it can be brought into an axial fastening position relative to the nail. Openings 12, 13 are thereby positioned in the fastening position of casing 10 in the area of slot 5 and with the latter, marrow nail 1 and casing 10 form a transverse channel 12, 5, 13 to admit bone fixation devices. |
