Document Type and Number:
Japanese Patent JP5885741
Kind Code:
B2
Abstract:
A method for producing a prosthetic acetabulum includes the following steps. First, one makes available a ceramic cup (1) that has a concave internal receiving face (3) and has an external annular receiving structure (6). Next, one makes available a placement and orientation insert (7) that has an annular peripheral fixing structure (10) designed to cooperate with the receiving face (9) of the external annular receiving structure (6) by engaging around the external annular receiving structure (6). Next, one heats the placement and orientation insert (7) in order to increase the dimensions of the insert. Next, one engages the annular peripheral fixing structure (10) around the receiving face (9) of the external annular receiving structure (6). Finally, one returns the placement and orientation insert (7) to ambient temperature in order to reduce the dimensions of the insert, in such a way as to obtain a radial clamping of the annular peripheral fixing structure (10) on the external annular receiving structure (6).
