Description
Technical Field
The invention relates to the technical field of femoral steel plates, in particular to a plum blossom-shaped guide steel plate for femoral neck fracture.
Background
With the frequent occurrence of traffic accidents, the fracture of neck of femur of young and middle-aged people tends to increase year by year. Different from the old, young patients are treated by hip protection surgery mostly, and are generally fixed by a plurality of hollow nails arranged in parallel. The biomechanical environment of the femoral neck is complex, the femoral head bears 237.7 percent of weight pressure, and the peripheral blood vessels of the femoral neck are easily interrupted by the influence of fracture displacement. Therefore, the clinical prognosis of femoral neck fracture is not ideal, the femoral head necrosis rate reaches 14.3%, the bone nonunion rate reaches 9.3%, and the reoperation rate reaches 13.0%. If not treated correctly, such fractures can remain disabled for life, and serious individuals can die.
Such surgical treatment of bone fractures places strict requirements on the position of the screws. The principle of fixing three hollow nails is as follows: welting, parallel and dispersed arrangement. The welt means that the screw is close to the cortex as much as possible in the femoral neck, so as to obtain the cortex support; the parallelism is to enable the three screws to form a whole body and provide better sliding and pressurizing effects on the fracture surface; the dispersion is to avoid three spikes from forming a point pressure and thus not being better able to resist torsion and shear forces. In addition, for unstable femoral neck fractures, a fourth off-axis screw would need to be driven vertically to provide better shear resistance.
In practice, however, the orthopedist is free-handed and it is difficult to achieve an optimal fixation position. Secondly, due to the narrow femoral neck space, the fourth screw is easily inserted into the femoral neck to collide with the other three screws, thereby causing the insertion and difficulty. The operation under direct vision is not realized, and the guide needle is frequently required to be repeatedly driven, so that not only is the bone lost and the stability is reduced, but also the damage of the blood vessel network in the bone is caused and the risk of femoral head necrosis is increased. This further increases the procedure time and X-ray exposure time due to the need for repeated fluoroscopy procedures, causing potential X-ray injury to the physician and patient. In addition, for osteoporotic patients, it is difficult for the hollow nail to obtain sufficient pressure, and even iatrogenic lateral wall and infratrochanteric fractures can occur. At present, an implanted guide steel plate is still lacked, and the functions of accurately positioning screws, increasing the stress of the screws and preventing iatrogenic fractures are realized.
