1. A bone anchor element configured for insertion into a bone and/or fixing tissue to the bone, wherein the bone anchor element comprises:
in a longitudinal direction, a proximal end, a proximal section, a distal section and a distal end,
wherein the proximal section has on an outside a contoured projection to prevent the bone anchor element when inserted into the bone from being pulled out, and, on an inside, a continuous hollow space in the longitudinal direction having a proximal opening and a distal opening,
wherein the distal section is a flattened, plate-shape configuration having a plate plane, wherein the plate plane is monolithic and includes two, parallel surfaces that bound the plate plane on an exterior portion,
wherein the distal section, in the longitudinal direction to the distal end, has a first transverse through-hole through the plate plane, wherein the first transverse through-hole is connected to the continuous hollow space of the proximal section via the distal opening, and a second transverse through-hole through the plate plane, wherein the first transverse through-hole and the second transverse through-hole are separated by a web of the plate-shaped distal section,
wherein the second transverse through-hole has on the distal end a gap opening in the longitudinal direction and transverse to the plate plane and configured such that a suture material can be flexibly-guided through the continuous hollow space, the first transverse through-hole, the second transverse through-hole and/or the gap opening, and the web has on its proximal side in relation to the first transverse through-hole an inclined abutment surface extending to one of the two, parallel surfaces that bound the plate plane on the exterior portion,
wherein the bone anchor element is configured so that when an eyelet is pushed through from the proximal opening through the continuous hollow space of the bone anchor element, through the distal opening and through the first transverse through-hole in the longitudinal direction, the eyelet is guided outward to one of the two, parallel surfaces upon contacting the inclined abutment surface through the first transverse through-hole.
