An acetabular implant is a device used in total hip replacement surgery to replace the acetabulum, the socket portion of the hip joint endoprosthesis. Endoprosthesis helps to recreate the anatomy of a hip joint and to restore its functions. Hip joint endoprosthesis consists of the following main components: a femoral stem, a liner and an acetabular component. These components may be standard or patient-specific. In cases of severe conditions (for instance, large bone defects, severe deformation, pelvic discontinuity or complications related to the existing implants), a patient-specific implant is recommended to be used. Patient-specific acetabular implants and patient-specific surgical guides are designed on a patient’s pelvic-femoral anatomical model recreated from computed tomography (CT) images.
