An anteromedial bone plate implanted in the distal femur

Abstract

The invention provides a bone plate implanted from the front inner side of the distal femur, belonging to the technical field of medical apparatus and instruments for the department of orthopaedics, and used for treating the condylar fracture and bone shaft fracture of the distal femur. The technical scheme is as follows: the bone plate is composed of a bone plate condylar part, a transitional face and a bone plate shaft part which are connected together, wherein the bone plate condylar part is opposite to the front inner side surface of the condyle of the distal femur, the lower surface of the bone plate condylar part is adaptive to the front inner side surface of the condyle of the distal femur in shape, the bone plate shaft part is opposite to the inner side surface of the distal femur, the lower surface of the bone plate shaft part is adaptive to the inner side surface of the distal femur in shape, and a plurality of fixing holes are uniformly distributed on the bone plate condylar part and the bone plate shaft part. The bone plate provided by the invention belongs to an innovation for the bone plate for the distal femur, therefore, the problem that when the existing bone plate is implanted from the outer side of the distal femur, the fixation for the condyle fracture on the inner side of part of the distal femur is not firm is solved, and the fracture blocks on the inner side of the distal femur can be effectively and firmly fixed, so that the heal of the fracture blocks on the inner side is promoted, and therefore, the bone plate has extremely good promotion and utilization values in the industry.

Description

technical field [0001] The invention relates to an implanted bone plate for treating distal femoral condyle fractures and shaft fractures in orthopedic surgery, and belongs to the technical field of orthopedic medical devices. Background technique [0002] In orthopedic clinical treatment, distal femoral condyle fractures and shaft fractures are common, mainly caused by violent impacts such as car accidents, falls, and bruises. At present, the treatment of distal femoral fractures is mostly carried out from the outer side of the distal femur, and a bone plate is implanted on the outer side of the femur for fixation. After a lot of clinical practice, it has been found that this surgical plan for bone plate fixation on the outer side of the distal femur has the following disadvantages: [0003] First of all, due to the influence of the shape of the femoral condyle, the distribution of screws is limited, and it is impossible to effectively and firmly fix the fracture fragment ...

AI Technical Summary

Problems solved by technology

[0003] First of all, due to the influence of the shape of the femoral condyle, the distribution of screws is limited, and it is impossible to effectively and firmly fix the fracture fragment in the medial part of the distal femur, which will affect the fracture healing or lead to the failure of the operation;

[0004] Secondly, due to the shape of the femur itself, it has an anterior arch in the coronal plane, and at the same time, it has an outward tension in the sagittal plane due to the pulling force of the lateral muscles. Fixed to resist the shear force caused by the force generated by the anterior bow shape of the femur itself when the fracture block is torsion;

[0005] Furthermore, the lateral side of the femur is the tension side, and the medial side is the pressure side. When a fracture occurs, the medial side is more crushed than the lateral side, and it is difficult to effectively fix the crushed bone fragments on the medial side. Even with locking plates, the medial pressure side remains For indirect fixation, prone to varus deformity and cannot be healed

[0006] To sum up, the technique of fixing the distal femoral lateral bone plate widely used in clinical practice has obvious shortcomings, which directly affects the fixation effect after distal femoral fracture, is unfavorable to the healing after fracture, and even causes The possibility of surgical failure, so it is necessary to improve the current fixation devices and methods for distal femoral fractures
