The invention relates to a prosthesis that can be implanted in the centre of wall wound scarring. The inventive prosthesis, which is intended for use in abdominal surgery, is provided with a geometric shape in the form of sheets that converge in dihedral angles. The sheets or planes are made from a synthetic biotolerated material in porous form with large pores. One of said planes is inserted into the centre of the scarring between the two aponeurotic surfaces to be joined. The other plane(s) of the prosthesis, which is perpendicular to the aforementioned plane, is arranged so as to overlap the aponeurotic edges of the edge of the section. The proliferation obtained around the prosthesis, in the scarring centre and close thereto, provides stress resistance greater than that obtained in standard closures, thereby greatly reducing the risk of hernias caused by a badly healed wound.
