Problems solved by technology

However, closed reduction and bone grafting are difficult, and the fracture defect cannot be effectively compensated, which increases the bed rest time of the patient; therefore, the healing time of the fracture is long, and the incidence of avascular necrosis of the femoral head is also high.

Abstract

The invention discloses a locking steel plate for femoral neck fracture reduction. The inner surface of the locking steel plate is bent to be matched with the greater trochanter of the femur; the locking steel plate comprises a steel plate head part, a steel plate body part and a steel plate tail part; a bone grafting hole is formed in the steel plate head part; three first screw holes which are formed in an isosceles triangle shape are formed in the locking steel plate, and the bottom edge of the isosceles triangle extends in the direction of the side edge of the locking steel plate. The locking steel plate can be used for making up the fracture defect part in the operation process of femoral neck fracture closing and reduction, the fracture healing rate is increased, and the risk of ischemic necrosis of the femoral head is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a locking steel plate for femoral neck fracture reduction. Background technique [0002] Femoral neck fracture refers to the fracture between the femoral head and the base of the femoral neck. Femoral neck fractures often occur in the elderly. As people live longer, especially with the aging population structure, the incidence of femoral neck fractures is increasing day by day. [0003] There are two main problems in the clinical treatment of femoral neck fractures: nonunion and avascular necrosis of the femoral head. There are many surgical methods for the treatment of femoral neck fractures clinically, and reduction and internal fixation are commonly used. If the patient is younger, hip replacement surgery is not required, and the femoral head is preserved, and reduction and internal fixation are often used. [0004] There are two methods of reduction an...
