Fitting-type bone fracture plate for inner side of femoral neck

Abstract

The invention discloses a fitting-type bone fracture plate for the inner side of the femoral neck, and belongs to the technical field of medical instruments for orthopedics departments. The fitting-type bone fracture plate comprises a head, a neck-shaft portion and a shaft which are integrated. Pressurizing holes and locking screw holes are distributed in the bone fracture plate along the length direction. Included angles between axles of the position holes and a plate body are different. The bone fracture plate is bent in the length direction, and the bending shape is matched with the radianof the inner side of the femoral neck. The bone fracture is bent in the width direction, and the bent plate surface is matched with the surface shape of the inner side of the femoral neck. The fitting-type bone fracture plate has the advantages that a conventional method of fastening the tension side of the outer side of the femoral neck is broken through, fracture pressure sides are fastened, andthe defects of conventional femur surgery is avoided effectively; the bone fracture plate fits the surface of the femur tightly due to the arc design, pressurized fixation and traction are combined,and good fixation effect is achieved, so that surgery time and recovery time are shortened greatly, and pain of patients is relieved effectively.

Description

technical field [0001] The invention relates to the technical field of orthopedic implants, in particular to a fitting type femoral neck medial bone plate. Background technique [0002] Femoral neck fracture is one of the common types of clinical fractures. With the acceleration of population aging, the incidence rate has increased significantly. Patients with proximal lateral femoral fractures have difficulty moving, which brings a lot of pressure to the patient's family. [0003] At present, in the operation of medial femoral neck fracture, in order to ensure the positioning accuracy of the fracture after surgical reduction and accelerate bone healing, internal fixation is often used. [0004] The principle of internal fixation treatment is to make an incision at the fracture end, place a bone plate so that the bone plate spans the fracture site, and use screws to fix the bone plate at the distal and proximal ends of the fracture so that the bone at the fracture end can b...

AI Technical Summary

Problems solved by technology

[0005] However, in the existing femoral neck fracture osteosynthesis surgery, the commonly used bone plate is the lateral femoral bone plate. Due to the limitation of bone plate structure, small incision surgery cannot be realized, which may easily lead to nonunion, and is not conducive to the treatment of multi-fragment fractures or comminuted fractures
