A micro-architectural evaluation of osteoporotic human femoral heads to guide implant placement in proximal femoral fractures

Abstract

The center of the femoral head contained the strongest trabecular bone, with the thickest, most dense trabeculae. The apical region was weaker. From an anatomical and mechanical point of view, implants that achieve fixation in or below this central core may achieve the most stable fixation during fracture healing.
