Abstract
The invention relates to guiding instruments (1) for guiding an acetabular cup implant as well as to impactors (13) for press-fitting an acetabular cup implant, both of which are of use during reconstructive joint surgery, more specifically during reconstructive hip joint surgery. The guiding instruments are characterized in that they fit onto an acetabular cup implant (8) and are designed to fit onto specific areas of the pelvic bone ensuring a unique fit on the bone. The impactors are characterized in that a fixation element (15) is connected to the stem (14) of the impactor by a ball joint. The invention also relates to combined guiding and fitting elements for an acetabular cup implant, comprising a guiding instrument and an impactor.
