A grouting method for rigidly connecting two elements using a binder, and in particular for anchoring one element, e.g. a prosthesis, in another, e.g. a bone cavity. According to the method, a through channel (10) is formed in advance in the element (1) to be anchored along an axis which is substantially parallel to that along which said element (1) is to be inserted into a socket (20) formed in the receiving element (2), and a binder (3) is injected into said channel (10) until the gap (21) between the element (1) and the wall of the socket (20) is full. Centering elements (23) may be placed around the element (1) in the space between said element (1) and the wall of the socket (20), and a sealing element (4) may be fitted around the element (1) to be anchored at the opening (22) of the socket (20). The injection channel (10) in the element (1) to be anchored may be threaded, to receive a screw rod allowing removal of the element (1).

Ce procédé consiste à pratiquer préalablement dans la pièce (1) à sceller un canal (10) traversant ladite pièce (1) selon un axe sensiblement parallèle à celui de l'introduction de ladite pièce (1) à sceller dans le logement (20) pratiqué dans la pièce (2) destinée à recevoir, et à injecter le liant (3) dans ledit canal (10) jusqu'à ce que ledit liant (3) remplisse l'espace (21) compris entre la pièce (1) et la paroi du logement (20). Des éléments de centrage (23) peuvent être placés autour de la pièce (1), dans l'espace (21) compris entre ladite pièce (1), et la paroi du logement (20), et une pièce d'étanchéité (4) peut être positionnée autour de la pièce (1) à sceller, sur l'ouverture (22) du logement (20). Le canal d'injection (10) pratiqué dans la pièce (1) à sceller peut êre muni d'un filetage permettant d'y introduire une tige filetée en vue de l'extraction de la pièce (1).
