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.

L'invention concerne une prothèse implantable dans le foyer de cicatrisation d'une blessure de paroi, destinée à être utilisée en chirurgie abdominale, présentant une forme géométrique de confluence de plaques en angles dièdres. Les plaques ou plans sont faits d'un matériau synthétique biotoléré de forme poreuse avec des pores de grande dimension. Un des plans est introduit dans le foyer de cicatrisation entre les deux surfaces aponévrotiques à unir. L'autre ou les autres plans de la prothèse, perpendiculaires à l'antérieur, sont disposés par chevauchement sur les bords aponévrotiques du bord de la section. La prolifération obtenue autour de la prothèse, dans le foyer de cicatrisation lui-même et à proximité, permet d'obtenir une résistance à la tension supérieure à celle obtenue dans les fermetures habituelles, rendant extrêmement difficile l'apparition d'hernies dues à une mauvaise cicatrisation.
