In elderly patients, the incidence of a second fracture in the contralateral hip within 2 years of a femoral neck fracture (FNF), ranges from 7 to 12%. We want to evaluate the safety and efficacy of the Prevention Nail System (PNS), a titanium screw with a hydroxyapatite-coated thread, developed to prevent contralateral FNFs in severe osteoporotic patients.Introduction
Hypothesis
Metal-on-metal hip resurfacing (MOMHR) is a good surgical indication for young active patients. However, it cannot be used in patients with an excessively short femoral head/neck. To address these cases, a new surgical technique has been developed comprising femoral head augmentation using impacted morcellized bone grafts. 32 osteoarthritis patients who had severe congenital insufficiency of the femoral head/neck were treated with MOMHR combined with femoral head augmentation. Mean patient age was 49 ± 9 years (18–66). The required amount of augmentation was calculated on preoperative X-rays and confirmed during surgery. Using specially designed instrumentation, bone chips produced while reaming the socket and trimming the head were impacted onto the head to achieve the desired reconstruction and lengthening. Finally, the femoral component was cemented.Introduction
