Introduction: The aim of this study was to examine whether the use of an internal electrostimulator could improve the results obtained with core decompression alone in the treatment of osteonecrosis of the femoral head.
Methods: We performed a retrospective study of 41 patients (55 hips) treated for osteonecrosis of the femoral head between 2005 and 2014. Mean follow-up time was 56 (12-108) months.
