Luigi Zagra, Eleonora Caboni

Research output: Contribution to journalReview article


Dual mobility cups are getting increasing interest for the prevention, but also in the treatment of THA instability. Nevertheless when a dislocation occurs the main issue remains the knowledge and the correction of the causes of dislocation, including reorientation of the components and soft tissues treatment. There are several options of alternative implants to DMCs including upsizing of the head, and constrained liners. The Authors present how to evaluate patients with THA instability, the advantages and the disadvantages of each procedure and their experience in the treatment of cases without DMCs during a five years’ time period.
