ACETABULAR COMPONENT FOR HIP PROSTHESIS OF RECONSTRUCTION OF HIP JOINT

摘要

An acetabular component (10) for a hip joint reconstruction prosthesis comprising: a semi-spherical cap member (11) having an external acetabulum anchor surface (12) and a surface internal coupling (13) with a corresponding articular surface of said hip prosthesis associated with the femur; anchoring means (14) for engaging said acetabular component (10) in the acetabular cavity of the hip; wherein said anchoring means (14) comprises a plurality of threaded members (14); wherein said semi-spherical cap member (11) is provided with a plurality of through holes (15) having an axis and configured to allow passage of the body (16) of said threaded members (14) and to block the head (17) of said threaded members (14); wherein said through holes (15) and said heads (17) of said threaded members (14) are configured to allow a first interlocking snap coupling at a plurality of inclinations of said threaded members (14) with respect to said axis (A) said through holes (15); wherein means are provided for locking (18) said threaded members (14) at a selected inclination with respect to said axes of said through holes.
