In order to solve the technical problems, the technical scheme of the invention is as follows: a hip joint prosthesis with prefabricated holes for treating the fracture around the prosthesis comprises a prosthesis handle arranged in the medullary cavity at the proximal end of femur, a through hole which forms a certain included angle with the axial lead of the prosthesis handle is arranged on the prosthesis handle, and a connecting screw for fastening the inner and outer cortex layers around the fracture is arranged on the through hole in a penetrating manner.
Preferably, there are at least two through holes, wherein at least two through holes are staggered and crossed to form an X-like shape.
Preferably, the tail cap of the connecting screw is provided with a through hole for binding a titanium cable or a steel wire in a cerclage way to further stabilize the fracture block if necessary.
Preferably, the angle between the through-going bore and the axis of the stem of the prosthesis is between 30 ° and 60 °.
The use method of the hip joint prosthesis with the prefabricated holes for conveniently treating the fracture around the prosthesis comprises the following steps: when the fracture is around the proximal end of the femoral prosthesis after operation, a through hole is drilled on the prosthesis handle at the corresponding part of the fracture, threaded holes coaxial with the through hole are drilled on the inner and outer cortex layers around the fracture, and connecting screws are screwed to fasten the inner and outer cortex layers around the fracture.
Preferably, the tail cap of the connecting screw is provided with a through hole, and a fracture block is further stabilized by cerclage binding of a titanium cable or a steel wire when necessary, and the titanium cable or the steel wire passes through the through hole when the cerclage binding is carried out.
Compared with the prior art, the invention has the following beneficial effects: this hip joint prosthesis who contains prefabricated hole convenient to fracture around treatment prosthesis for fracture around the proximal end of prosthesis handle runs through the through-hole direction and can wear to establish according to actual conditions, and the direct utilization is worn to establish connecting screw on running through the through-hole and is fastened the two-layer cortex of inside and outside around the fracture, and the fastening is firm, and easy operation is convenient high-efficient, uses reasonable convenience more to the prosthesis proximal end that is difficult to place the steel sheet, stable in structure.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
