A surgical implant intended to allow a fusion between a first bone portion and a second bone portion, the surgical implant comprising at least: - a first anchoring part configured to be anchored in the first bone portion, the first anchoring part including at least two first branches (11, 12), the first branches (11, 12) being displaceable between: • an introduction position, in which the respective ends of the first branches (11, 12) define a first introduction distance (D10.1), so as to allow the introduction of the first branches (11, 12) inside the first bone portion, and • an anchoring position, in which the respective ends of the first branches (11, 12) define a first anchoring distance (D10.2) larger than the first introduction distance (D10.1), such that the first branches (11, 12) are adapted to anchor the first anchoring part inside the first bone portion, - a second anchoring part configured to be anchored in the second bone portion, - an intermediate part linking the first anchoring part to the second anchoring part; the surgical implant being characterized in that: - the intermediate part includes at least: • a recess, • a first bonding portion disposed between the first anchoring part and the second anchoring part, and • a second bonding portion disposed between the first anchoring part and the second anchoring part, the first bonding portion and the second bonding portion being arranged on either side of said at least one recess such that the first bonding portion is spaced apart from the second bonding portion, and - the intermediate part is shaped such that bringing the first bonding portion and the second bonding portion closer to each other, displaces the first branches (11, 12) from their introduction position to their anchoring position. - a first anchoring part configured to be anchored in the first bone portion, the first anchoring part including at least two first branches (11, 12), the first branches (11, 12) being displaceable between: • an introduction position, in which the respective ends of the first branches (11, 12) define a first introduction distance (D10.1), so as to allow the introduction of the first branches (11, 12) inside the first bone portion, and • an anchoring position, in which the respective ends of the first branches (11, 12) define a first anchoring distance (D10.2) larger than the first introduction distance (D10.1), such that the first branches (11, 12) are adapted to anchor the first anchoring part inside the first bone portion, • an introduction position, in which the respective ends of the first branches (11, 12) define a first introduction distance (D10.1), so as to allow the introduction of the first branches (11, 12) inside the first bone portion, and • an anchoring position, in which the respective ends of the first branches (11, 12) define a first anchoring distance (D10.2) larger than the first introduction distance (D10.1), such that the first branches (11, 12) are adapted to anchor the first anchoring part inside the first bone portion, - a second anchoring part configured to be anchored in the second bone portion, - an intermediate part linking the first anchoring part to the second anchoring part; - the intermediate part includes at least: • a recess, • a first bonding portion disposed between the first anchoring part and the second anchoring part, and • a second bonding portion disposed between the first anchoring part and the second anchoring part, the first bonding portion and the second bonding portion being arranged on either side of said at least one recess such that the first bonding portion is spaced apart from the second bonding portion, and • a recess, • a first bonding portion disposed between the first anchoring part and the second anchoring part, and • a second bonding portion disposed between the first anchoring part and the second anchoring part, the first bonding portion and the second bonding portion being arranged on either side of said at least one recess such that the first bonding portion is spaced apart from the second bonding portion, and - the intermediate part is shaped such that bringing the first bonding portion and the second bonding portion closer to each other, displaces the first branches (11, 12) from their introduction position to their anchoring position.
