A reduction support structure for femoral neck fracture

Abstract

The invention discloses a reduction support structure for femoral neck fractures. The reduction support structure comprises a locking steel plate, a sleeve and first screws; the inner surface of the locking steel plate is curved to be matched with the femoral large trochanter; the locking steel plate comprises a steel plate head, a steel plate trunk and a steel plate tail; three first screw holesarranged in an isosceles triangle shape are formed in the locking steel plate, and the bottom edge of the isosceles triangle extends in the side edge direction of the locking steel plate; the sleeve is arranged in the first screw holes; the tails of the first screws are arranged in the sleeve. The reduction support structure can achieve stable reduction support for the femoral neck fractures; theoperation is simple, the reduction effect is good, and the injuries to patient are small.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a reduction support structure for femoral neck fractures. 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 and internal fixation. Th...

Problems solved by technology

However, because the lateral plate is located on the lateral side of the femur, the defect of the medial cortex may cause accidents such as screw cutting of the femoral head, displacement of the internal fixation, or prolapse of the screws on the side of the plate.

Therefore, the failure rate of the traditional DHS fixation system is as high as 24% to 56%, and the operation time is longer and the bleeding volume is more
