In orthopedic patients, with the increase of the number of hip joint replacements, the incidence rate of postoperative fracture around femoral prosthesis also increases significantly, the most common fracture around prosthesis in clinic occurs in fracture at the far end of femoral stem, and the fracture is also a difficult point in clinical treatment. Because patients are mostly old people and are generally combined with osteoporosis, steel plate and steel cable cerclage fixing operation treatment is mostly adopted clinically, but because the prosthesis handle occupies the space in the medullary cavity at the proximal end of the femur, only a single cortical screw can be placed when the steel plate is fixed, the stability of the steel plate fixation is influenced, and the steel cable cerclage fixing is adopted, because the steel cable ring is poor in flexibility and cannot be well attached to the bone wall, the postoperative patient has obvious foreign body sensation, and the body discomfort is caused; and the steel cable ring needs to adopt the euphroe to fix, and the terminal surface of steel cable ring forms the burr, easily hooks the tissue, causes strong uncomfortable sense. In addition, after the operation is successful for a certain time, according to the prior art, the patient still needs to go to the hospital and be injured again to perform nail, plate and cable detaching operations, tissues corresponding to the positions of the steel cable rings need to be cut in sequence, the steel cable rings need to be detached in sequence, and the secondary wound of the patient is large. For patients with poor bone quality, the implanted nails, plates and cables cannot be detached, and the implanted nails, plates and cables need to be left in the body all the time to assist in fixing the thighbone of the human body, so that the strength safety is ensured; the removal and non-removal of the nails, plates and cables all bring great physical, life and mental pressure to the patient on different levels.
