Double Medical Proximal Femoral Bionic Nail PFBN

Double Medical Proximal Femoral Bionic Nail was jointly developed on the basis of the original patent of “triangle stable structure” by Academican Zhang Yingze and the theory of “leverage-fulcrum reconstruction” proposed by Professor Zhang Dianying. For details please check link: https://www.doublemedicalgp.com/proxi... Indications Low and extended subtrochanteric fractures Ipsilateral trochanteric fractures Multilateral fractures (proximal femur) Pathological fractures "Leverage-fulcrum reconstruction" theory 1.The anatomy of the normal human hip joint is similar to a lever system. The fulcrum is located near the center of the femoral head, the lever arm of the medial compressive group is shorter, and the lever arm of the lateral tensile group is longer. Therefore, the hip joint can bear a greater weight and perform various actions. 2.The purpose of the operation is to establish a new lever system through the internal fixation system to replace the original lever system until the fracture is healed. 3.The postoperative stability of fracture depends on the type of fixation, and has no relationship with the types of the fracture. 4.The fulcrum reconstruction position of new internal fixation system is more closer to the anatomical and physiological fulcrum, the more stable the postoperative fracture will be.
