1. A bone anchor for a suture thread or ligament, comprising:
a main body extending along a longitudinal axis and having a fork-shaped end portion, said end portion being provided with a first fork arm and a second fork arm, each fork arm extending between a constrained end and a free end and spaced from each other by an axial slit for receiving a suture thread or ligament,
wherein the first fork arm and the second fork arm each have a circumferential notch defining, at the constrained end, a portion of reduced width so that the first fork arm and the second fork arm have, from the constrained end to the free end, an “L” or “J” conformation, wherein:
the first fork arm and the second fork arm are arranged in polar symmetry with respect to the longitudinal axis, and the first fork arm and the second fork arm do not have reflectional symmetry relative to a plane that is disposed equidistant between an inner face of the first fork arm and an inner face of the second fork arm, wherein the inner faces face each other to delimit the axial slit.
