Abstract:
The number of hip revision surgeries is expected to increase in recent years, and reconstruction of acetabular defects is a challenge for joint surgeons. The principle of reconstruction of acetabular defects is to achieve initial and long-term stability between the prosthesis and the host bone. With the development of surgical techniques, prosthetic materials, and revision concepts, there is an urgent need for new acetabular bone defect evaluation systems to meet clinical needs. The uncemented porous hemispherical cup has become the main prosthesis in clinical application, and metal augments are gradually replacing the structural allograft. Modular reconstruction combined cups and augments has shown favorable clinical results, which can be used for large acetabular defects with acetabular distraction technique, such as pelvic discontinuity. The advantages and disadvantages of impaction bone grafting, jumbo cups, metal augments, acetabular reinforcement rings, custom components (including custom triflanged acetabular components), and acetabular distraction technique still need to be observed in long-term follow-up.
