Problems solved by technology

[0002] At present, the commonly used femoral neck fractures are mostly fixed with hollow screws. Due to various reasons, especially the large shear stress of type 3, the screws may break, and common complications such as avascular necrosis and nonunion may result, resulting in major medical accidents.
At present, femoral neck fractures are usually placed in the supine position, and the anterior approach is used for reduction. The failure rate is about 20%. The main reasons for failure are unsatisfactory reduction, poor bone union, and screw breakage. Problems with high difficulty and complicated operation

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] Such as Figure 1-5 As shown, a bone screw-type medial support plate for femoral neck fractures includes an arc-shaped steel plate 1 and several bone screws 2. The arc-shaped steel plate 1 is butterfly-shaped and its surface is provided with several bone screw holes arranged in a line , the bone screw 2 is adapted to the hole of the bone screw.

[0024] To facilitate long-term implantation in the human body, the material of the curved steel plate 1 is medical stainless steel, superelastic material, biodegradable material or material capable of producing martensitic deformation between -10°C and 45°C.

[0025] Similarly, the material of the bone screw 2 is medical stainless steel, superelastic material, biodegradable material or material capable of producin...

Abstract

The invention discloses a bone screw type femoral neck fracture inner side supporting steel plate which comprises an arc-shaped steel plate and a plurality of bone screws; the arc-shaped steel plate is in a butterfly wing shape, the surface of the arc-shaped steel plate is provided with a plurality of bone screw holes arranged in a straight line, and the bone screws are matched with the bone screw holes; and the arc-shaped steel plate is made of medical stainless steel material, hyperelastic material, biodegradable material or material capable of generating martensite deformation at the temperature ranging from -10 DEG C to 45 DEG C. The bone screw type femoral neck fracture inner side supporting steel plate is simple in structure, firm and durable, the arc-shaped steel plate is tightly attached to the femoral neck, supporting is provided on the inner side of the femoral neck, the longitudinal shearing force of the femoral neck is reduced, and secondary fracture of the femoral neck after an operation is prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone screw-type medial support plate for femoral neck fracture. Background technique [0002] At present, the commonly used femoral neck fractures are mostly fixed with hollow screws. Due to various reasons, especially the large shear stress of type 3, the screws may break, and common complications such as avascular necrosis and nonunion may result, resulting in major medical accidents. . At present, femoral neck fractures are usually placed in the supine position, and the anterior approach is used for reduction. The failure rate is about 20%. The main reasons for failure are unsatisfactory reduction, poor bone union, and screw breakage. Medium difficulty, complex operation and other problems. Contents of the invention [0003] The present invention aims to provide a medial support plate for femoral neck fractures, which can support the medial side of the femoral ne...
