Bone fracture plate with arc-shaped plate

Abstract

The invention relates to a bone fracture plate with an arc-shaped plate, and belongs to the technical field of human body internal implantation materials. The bone fracture plate is formed by a main plate and the arc-shaped plate, the arc-shaped plate is manufactured on one side of the main plate, the main plate and the arc-shaped plate are in circular arc transition to form a whole, locking holes are formed in the main plate and the arc-shaped plate, a hollowed structure is formed in the middle of the arc-shaped plate, and the main plate and the arc-shaped plate are in circular arc transition to form the whole and fixedly attached to the thighbone through locking nails. According to the bone fracture plate, the arc-shaped plate is additionally arranged on one side of the original main plate, the thighbone can be supported and fixed in a semi-wrapped and attached mode, and the bone fracture reduction effect and the supporting intensity on the inner side of an intertrochanteric fracture and the firmness of the main plate are improved. The bone fracture plate is wide in application range and can be used for all the stable and unstable intertrochanteric and below-trochanter fractures and splintered fractures of inner-side thighbone calcars and lesser trochanters, the risks of coxa vara, nail breaking and plate breaking are effectively reduced, complications are reduced to the greatest extent, the treatment effect improved, and the bone fracture plate is easy and convenient to install and safe and stable in use.

Description

technical field [0001] The invention relates to a bone plate with a curved plate, which belongs to the technical field of implants in human body. Background technique [0002] Intertrochanteric fracture is a common clinical orthopedic disease, often due to improper treatment resulting in coxa varus and hip external rotation deformity and disability or fatal complications. At present, surgical internal fixation is mostly used for the treatment of intertrochanteric fractures at home and abroad. The internal fixation materials include intramedullary fixation system and extramedullary fixation nail-plate system. Among them, the intramedullary fixation system requires high surgical operation accuracy and will damage and It hinders the blood supply in the femoral medullary cavity, leading to a high incidence of complications such as fat embolism, high risk, and difficult removal in the later stage, which limits its clinical promotion to a certain extent. Because the extramedullar...

AI Technical Summary

Problems solved by technology

It solves the problem that the existing technology cannot be half-wrapped and fit to the femoral support for fixation, the compressive stress on the implant is large, the stability is poor, and there are often complications such as screw loosening, plate distortion and fracture, screw cutting of the femoral head, and coxa varus deformity. bone plate
