Embodiment Construction

[0019] refer to Figure 1-4 A bone anchor screw according to a first embodiment of the present invention will be described. The bone anchoring screw comprises an anchor rod 1 having a free end 2 and a head 3 opposite to the free end 2 . A coaxial hole 4 extends through the anchor rod from the end where the head 3 is located to a distance from the free end 2 . The diameter of the coaxial hole 4 is such that the bolt has sufficient strength against damage.

[0020] A plurality of openings 5 ​​extend from the bore 4 through the wall of the bolt 1 to the outside in radial direction. The cross-section of the opening is preferably circular or otherwise circular. The openings may be arranged in a regular manner, for example in circumferential rows, with one row offset relative to the other to provide an even distribution of the openings in the portion of the bolt 1 . As shown in the figures, there may be a part of the bolt 1 adjacent to the head 3 in which no opening is provided....

Abstract

A bone anchoring nail is provided having a threadless shaft (1') with a free end (2), a head (3') opposite to the free end, the head having a substantially U-shaped recess (7) for accommodation of a rod (12) or a rod-shaped element, a longitudinal bore (4) extending through the shaft and opening towards at least the head (3') or the free end (2) and a plurality of openings (5) extending through the wall of the shaft and being in communication with the bore (4). The bone anchoring nail allows quick insertion and reliable fixation enhanced by the in-growth of blood vessels.

Description

technical field [0001] The invention relates to a bone anchor nail. In particular, the present invention relates to a bone anchor having a shank with a longitudinal hole and a plurality of openings in the wall of the shank; U-shaped groove. The bone anchoring screw may be used, for example, to anchor a spinal rod into the pedicle of an adjacent vertebra for stabilizing the spine, or the bone anchoring screw may be used in any other type of bone anchoring application using a rod or rod-like element . Background technique [0002] A bone anchoring device in the form of a bone screw comprising a screw head and a threaded shaft is known from WO 01 / 26568, wherein an axial hole is provided which is connected to the outside by a plurality of radial holes. Bone cement may be injected through the bone screw into the bone tissue surrounding the threaded rod. US2004 / 0147929A1 discloses a bone anchoring device having a tubular element having a bone threaded portion on its outer wall...
