Dual Mobility Cup in Total Hip Arthroplasty Preventing Dislocation in Patients at Risk

Retrospectively study reviewing 34 patients operated with dual mobility cups in total hip arthroplasty between January 2009 and June 2012 at Sundsvall Hospital.

Hypothesis: The dual mobility socket reduce the rate of dislocation in patient at high risk but increase the incidence of postoperative infection.
