Dual mobility total hip arthroplasty: should everyone get one?

[摘要] The challenges of hip arthroplasty have evolved over the decades. There was a time when arguments flared between supporters and opponents of different fixation methods or bearing materials. More recently, in the era of personalized medicine, we aim to reproduce the patient’s native anatomy and the physiological articular environment, aiming to improve prosthetic kinematics and restoring normal function. Our new quest is to offer a forgotten hip joint to our patients. Currently, two factors may compromise this achievement: hip range of motion (ROM) restrictions and hip instability. One option addressing these two problems is the dual mobility (DM) articulation. This very old French invention, used since 1974 by Gilles Bousquet in Saint-Etienne (France), takes the double principle of a small articulation to minimize the problems of wear, coupled with a large articulation to stabilize the hip and prevent instability.
