Patients with a femoral fracture due to osteoporosis are at high risk of sustaining a secondary fracture on the contralateral side. A prophylactic mechanical reinforcement of the contralateral side during operation of the initial fracture could be of interest for such patients. This biomechanical in vitro study investigates the potential of a limited V-shaped bone cement augmentation to prevent secondary hip fractures by targeting the areas of the proximal femur with the highest stresses during a fall. ⋯ No significant differences were found between the two groups for fracture load (p = 0.5), yield load (p = 0.35) and stiffness (p = 0.5). Biomechanically, a limited V-shaped prophylactic cement augmentation carries potential to prevent secondary hip fractures indicated by increased energy absorption until fracture. Further investigations are necessary to minimize interference with the biology and to maximize the mechanical benefit of prophylactic augmentation.
