    摘要: A surgical instrument (10) is described for the implanting of acetabular components of hip prostheses. The instrument comprises a main stem (12) which acts as a dynamometric impactor for obtaining the implantation of the acetabular component and which comprises at least one torsional dynamometer (14), coaxial to the main stem (12), for the application and measuring of a torsional moment on the acetabular component implanted. The instrument also comprises a side mechanism (16), which includes a secondary stem (18), parallel to the main stem (12), a handle (20) and at least one axial dynamometer (22), orthogonal to the stem (18), which connects the secondary stem (18) to the handle (20) for the application and measuring of a destabilizing force on the acetabular component implanted.
