Device to assist the implantation, and allow the removel of, a hip prosthesis shaft

Abstract

Abstract The invention relates to a device intended to assist in the implantation of a hip prosthesis shaft (1) in a medullary cavity of the femur, and to allow the removal of the said prosthesis shaft. This device comprises in the first instance a hip prosthesis (1) consisting of a femoral stem (3) and an upper pivot (5, 6) and equipped with a recess formed on the said upper pivot. It additionally comprises an impactor/extractor element (2) comprising a body (9) having two jaws (15, 19) which are of shapes complementing the upper pivot (5, 6) of the prosthesis shaft (1) and are designed to grip the said pivot, and the said jaws comprising an inner stud (23) projecting in such a way as to engage in the recess of the prosthesis shaft (1), and means (21) for relative displacement of the two jaws (15, 19). <IMAGE>
