Intertrochanteric arc-shaped bone fracture plate

Abstract

The invention relates to an intertrochanteric arc-shaped bone fracture plate, and belongs to the technical field of human in-vivo implantation materials. The intertrochanteric arc-shaped bone fracture plate is composed of a main plate and an 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 connected as a whole through a connecting arc face, locking holes are formed in the main plate and the arc-shaped plate, and the bone fracture plate and the thighbone are attached and fixed through screws. A hollowed-out structure is formed in the middle of the arc-shaped plate. The arc-shaped plate is added to one side of the main plate, semi-wrapping attachment supporting and fixing can be carried out on the thighbone, the fracture reduction effect and supporting force of the inner rear side of an intertrochanteric fracture and the firmness of the main plate are improved, and more than eight locking holes fixed to the whirlbone through the femur neck are provided to be selected. The application range is wide, the intertrochanteric arc-shaped bone fracture plate can be used for all stable and unstable intertrochanteric and subtrochanteric fractures, inside calcar femorale and lesser trochanter splintered fractures and femur neck fractures, the risks of coxa vara, nail breakage and plate breakage are effectively reduced, the treatment effect is improved, mounting is easy and convenient, and use is safe and stable.

Description

technical field [0001] The invention relates to an intertrochanteric arc-shaped bone 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 ext...

Problems solved by technology

Solve the intertrochanteric femoral problems that cannot be half-wrapped and fitted to the femoral support in the existing technology, and the compressive stress on the implant is large, the stability is poor, and there are often complications such as screw loosening, plate twisting and fracture, screw cutting of the femoral head, and coxa varus deformity. curved bone plate
