Problems solved by technology

[0004] However, in actual operation, orthopedic surgeons operate with bare hands, and it is difficult to achieve the best fixed position
Secondly, due to the narrow space of the femoral neck, the insertion of the fourth screw is likely to conflict with the other three screws, resulting in extremely difficult insertion
Due to the inability to operate under direct vision, it is often necessary to insert the guide pin repeatedly, which not only causes bone loss and reduces stability, but also causes damage to the intraosseous vascular network and increases the risk

Embodiment approach

[0041] In a further embodiment of the present invention, the outer edge of the steel plate body 1 is protruding and forms a protruding edge 101 along the outer periphery of the steel plate body 1, and the protruding edge 101 is convex toward the side away from the femur 4 relative to the steel plate body 1 From the shape. Further, the protruding edge 101 adopts a low notch setting, which reduces blood supply damage and tissue irritation, and facilitates the insertion of the entire steel plate body 1 .

[0042] In a further embodiment of the present invention, the edge of the first side end 13 away from the middle body 12 is arc-shaped, the edge of the second side end 14 away from the middle body 12 is arc-shaped, and the upper end 11 is far away from the edge of the middle body 12. The edges are arranged in an arc shape, and the edge of the second lower end portion 16 away from the middle body 12 is arranged in an arc shape. Further, the width from the first side end portion ...

Abstract

The invention discloses a plum blossom guide steel plate for femoral neck fracture. The steel plate comprises a steel plate body, the steel plate body comprises an upper end part, a middle main body, a first side end part, a second side end part, a first lower end part and a second lower end part, and the upper end part, the middle main body, the first side end part, the second side end part, the first lower end part and the second lower end part are of an integrated structure; the upper end is arranged at the upper end of the middle body, the first lower end is arranged at the lower end of the middle body, the second lower end is arranged at the lower end of the first lower end, the first side end is arranged on one side of the middle body, and the second side end is arranged on the other side of the middle body. The upper end part, the middle main body, the first side end part, the second side end part, the first lower end part and the second lower end part are all clung to the femur; a first nail placing hole is formed in the end part of the first side; and a second nail placing hole is formed in the end part of the second side. Through the application of the device, the parallel hollow nails can be accurately nailed, the most stable fixing effect is achieved, repeated operation is avoided, the operation and fluoroscopy duration is shortened, and iatrogenic fractures are avoided.

Description

technical field [0001] The invention relates to the technical field of femoral steel plates, in particular to a quincunx guiding steel plate for femoral neck fractures. Background technique [0002] With the frequent occurrence of traffic accidents, femoral neck fractures in young and middle-aged people tend to increase year by year. Unlike the elderly, young patients are often treated with hip-preserving surgery, and are generally fixed with several hollow nails arranged in parallel. The biomechanical environment of the femoral neck is relatively complex. The femoral head bears the pressure of 237.7% of the body weight, and the blood vessels around the femoral neck are easily interrupted by fracture displacement. Therefore, the clinical prognosis of femoral neck fracture is not satisfactory, the femoral head necrosis rate is 14.3%, the nonunion rate is 9.3%, and the reoperation rate is 13.0%. If this type of fracture is not properly treated, it can leave lifelong disabili...
