An osseous anchoring implant with facilitated extraction, comprising: An expandable sleeve extending between a proximal portion having a first internal diameter, and a distal portion having a second internal diameter smaller than said first internal diameter, these two portions defining a longitudinal axis (L) and said first and second internal diameters defining an internal profile of said expandable sleeve , and comprising, on the one hand, at least a first threading inside the expandable sleeve and, on the other hand, at least a second threading outside the expandable sleeve , A screw extending between a proximal portion and a distal portion on an axis collinear with the axis (L) and having, on the one hand, along said longitudinal axis (L), an external profile complementary to said internal profile of said expandable sleeve and, on the other hand, at least one external threading whose screw pitch is reversed relative to said second external threading of the expandable sleeve , The implant being able to switch from a folded rest position to a deployed position by the actuation of said reversed threadings by causing the penetration of the screw into the expandable sleeve and generating the expansion of said expandable sleeve by deformation, thanks to the fact that the external diameter of the screw is greater, at least on a distal portion, than said second internal diameter of the expandable sleeve , In the deployed position of the implant, the second internal diameter of the expandable sleeve being greater than or equal to the first internal diameter, Characterized in that The distal portion includes a head comprising at least one rear flute with a cutting edge to mill the bone during the extraction of the osseous implant and facilitate the removal of the implant.
