[0005] Further, the steel plate is made of stainless steel or titanium alloy.

[0006] Further, the steel plate is provided with fixing hole I, fixing hole II and fixing hole III, the screw I is implanted into the non-fracture area of the bone through the fixing hole I, and the screw II and the screw III are implanted into the fracture area of the bone through the fixing hole II and the fixing hole III respectively.

[0007] Further, the diameter of the screw III is greater than that of the screw II.

[0008] Further, the combination screw is implanted according to the range of the fracture area, and the combination screw is arranged up and down, arranged front and back or arranged crosswise.

[0009] Compared with the prior art, the utility model has the advantages of:

[0010] The fixed structure is ingenious in design, the combined screw is implanted to reduce the occurrence rate of steel plate bending and breaking in the case that the bone defect on the opposite side of the steel plate has no enough support, and the fixed structure is convenient and safe to operate, is widely applicable to orthopedic surgery, and realizes strong internal fixation of orthopedic surgery.
