DUAL MOBILITY CUP IN THE TREATMENT OF UPPER FEMORAL FRACTURES: PROSPECTIVE STUDY AT ONE YEAR OF FOLLOW-UP

IntroductionUpper femoral fractures include intra and extra-capsular fracture (ECF). For intra-capsular fracture (ICF), hemi-arthroplasty (HA) is the most commonly used treatment. Interest in total hip arthroplasty (THA) is growing because THA yields less revision (4% versus 7%) associated to better functional results despite higher dislocation rate (9% versus 3%). Regarding ECF, internal fixation is the reference treatment. THA could represent a relevant alternative. This study evaluates the efficiency of THA using dual mobility cup (THA-DMC) as treatment of these fractures specially in elderly patients.Material and method70 patients were operated on for upper femoral fractures with Quattro THA-DMC between May 2012 and October 2013. Minimum follow-up is one year. Seven surgeons in 4 institutions were involved. Data collected were: age, gender, type of fracture, surgical approach, mortality, revision rate and dislocation rate.ResultsSeventy patients were included. 83.3 % were women. Mean age was 82.8 (51–...
