The longest follow-up dual mobility series from inventor Gilles Bousquet focussing on implant survival and the incidence of dislocation.
This was a retrospective study from 1985 to 1990, on 240 hips using a PF modular femoral stem and a dual mobility Novae tripodal socket (SERF).
The dual mobility socket global survival rate is comparable to similar series. The 0% dislocation rate demonstrates the success of dual mobility with regard to implant stability. The main issues were cup fixation, which might be improved by the use of macrostructures and HA coating, and osteolytic lesions, caused by polyethylene wear. Traditionally suitable for patients older than 60 years, dual mobility might be extended for use in patients over 50.
