Dual mobility total hip arthroplasty: should everyone get one?
Hip instability following total hip arthroplasty (THA) remains a major challenge and is one of the main causes of revision surgery. Dual mobility (DM) implants have been introduced to try to overcome this problem. The DM design consists of a small femoral head captive and mobile within a polyethylen...

description | Hip instability following total hip arthroplasty (THA) remains a major challenge and is one of the main causes of revision surgery. Dual mobility (DM) implants have been introduced to try to overcome this problem. The DM design consists of a small femoral head captive and mobile within a polyethylene liner. Numerous studies have shown that DM implants reduce the rate of dislocation compared to fixed-bearing inserts. Early designs for DM implants had problems with wear and intra-prosthetic dislocations, so their use was restricted to limited indications. The results of the latest generation of DM prostheses demonstrate that these problems have been overcome. Given the results of these studies presented in this review, surgeons may now consider DM THA for a wider patient selection. Cite this article: EFORT Open Rev 2019;4:541-547.
