[0017] Such as figure 2 The shown protection steel plate for the lateral femur wall includes a protection steel plate for the lateral femur wall, including a main body 1 of the protection steel plate. The main body 1 of the protection steel plate is provided with a steel plate extension end 2 on the side close to the small nodules of the femur. One end of the extension end 2 of the steel plate is connected to the main body 1 of the protective steel plate, and the other end is bent to fit the small nodules of the femur and is provided with a small nodule fixing hole 3. The main body of the protective steel plate 1 is provided with a spiral blade passing hole 4 in the middle. 1 On both sides of the upper spiral blade passing hole 4 are opened large nodules fixing holes 5 and suture holes 6, and the lower part is opened with 2 femoral shaft fixing holes 7. The spiral blade of the protective steel plate body 1 passes through the upper and lower sides of the hole 4 Temporary fixing ...

Embodiment 3

[0020] Such as image 3 with Figure 4 The shown protection steel plate for the lateral femur wall includes a protection steel plate for the lateral femur wall, including a main body 1 of the protection steel plate. The main body 1 of the protection steel plate is provided with a steel plate extension end 2 on the side close to the small nodules of the femur. One end of the extension end 2 of the steel plate is connected to the main body 1 of the protective steel plate, and the other end is bent to fit the small nodules of the femur and is provided with a small nodule fixing hole 3. The main body of the protective steel plate 1 is provided with a spiral blade passing hole 4 in the middle. 1 On both sides of the upper spiral blade passing hole 4 are provided large nodules fixing holes 5 and suture holes 6, and 3 femoral shaft fixing holes 7 are opened in the lower part. The spiral blade of the protective steel plate body 1 passes through the upper and lower sides of the holes 4 ...

Abstract

The invention discloses a thighbone outer side wall protection steel plate. The thighbone outer side wall protection steel plate comprises a protection steel plate main body, a steel plate extending end is arranged on the side, close to the tubercula minus, of the protection steel plate main body, one end of the extending end of each steel plate is connected to the protection steel plate main body, the other end is bent to be attached to the tubercula minus and is provided with a nodule fixing hole, a screw blade through hole is formed in the middle of the protection steel plate main body, a greater tubercle fixing hole and a suture hole are formed in the protection steel plate main body along the two sides of the screw blade through hole, a femoral stem fixing hole is formed in the lowerportion of the protection steel plate main body, and temporary fixing holes are formed in the upper side and the lower side of the screw blade through hole of the protection steel plate main body. Thedevice can effectively reduce the distance of the femoral head and neck lag screw sliding out of the screw, and can reduce the occurrence rate of outer side wall rupture and the re-operation rate.

Description

Technical field [0001] The invention relates to the technical field of femoral treatment instruments, in particular to a protective steel plate for the lateral wall of the femur. Background technique [0002] Fractures of the proximal femur are often accompanied by comminuted, missing and incomplete lateral wall. After the intramedullary nail is fixed, there are still unstable factors in the lateral wall area. From the perspective of mechanical principles, the intramedullary nail only provides support for the inner wall and the bone axis, and the lateral wall still lacks effective support. Summary of the invention [0003] The purpose of the present invention is to provide a protective steel plate for the lateral wall of the femur to solve the problem that the intramedullary nail proposed in the background art only provides support for the inner wall and the bone axis, but the lateral wall still lacks effective support. In order to achieve the above object, the present invention ...
