Description
Technical Field
The invention belongs to the field of medical instruments, and particularly relates to a bone fracture plate for proximal femur fracture.
Background
Femur, also called femur, is the biggest bone of the whole body, and proximal femur fractures such as femoral neck fractures, intertrochanteric fractures and subgreater trochanter fractures of the femur are all common serious injuries of the femur. Because of the anatomical specificity of the femoral neck, once fracture occurs, the reduction and fixation of the femoral neck are very difficult, and fracture nonunion and ischemic necrosis of the femoral head often occur, so that the disability rate is high. Fracture of the femoral trochanter can be caused by direct impact of violence, falling from a high place, vehicle impact, rolling and the like. When the femur fracture occurs, the lower limb can not move, the fracture is severely swollen and painful, deformities such as torsion or angulation can also occur, and sometimes the length of the lower limb can be shortened. If there is an open wound, the condition is more serious, and the patient is often shocked. If not treated in time after fracture, severe complications such as hemorrhage and nerve injury of patients can be caused. There are many current methods of treatment and internal fixation devices for proximal femur fractures.
