Embodiment 1

[0014] refer to figure 1 , the present embodiment provides a support structure inside the medullary canal for internal fixation of proximal femoral fractures, including a fixation plate 1, on which at least two screw holes are opened, designed for locking screw holes, and the fixation plate 1 is arranged on the femoral marrow The inner side of the cavity is set close to the inner side of the femur, and the fixing plate 1 is fixed on the femur through the screws 2 arranged in the screw holes. For bicortical fixation, the fixation plate 1 can be made of metal materials such as titanium alloys that can be implanted into the human body, or can be made of polymers or plastics such as PEEK materials that can be implanted into the human body, and can be selected according to the required fixation strength of the fracture site.

[0015] The fixation plate 1 is placed alone on the inner side of the femoral medullary cavity to support the inner side, share the inner side pressure, and r...

Embodiment 2

[0017] refer to figure 2 , the present embodiment provides a support structure inside the medullary canal for internal fixation of proximal femoral fractures, including a fixation plate 1, on which at least two screw holes are opened, designed for locking screw holes, and the fixation plate 1 is arranged on the femoral marrow The inner side of the cavity is set close to the inner side of the femur, and the fixing plate 1 is fixed on the femur through the screws 2 arranged in the screw holes. For bicortical fixation, the fixation plate 1 can be made of metal materials such as titanium alloys that can be implanted into the human body, or can be made of polymers or plastics such as PEEK materials that can be implanted into the human body, and can be selected according to the required fixation strength of the fracture site.

[0018] The fixation plate 1 is used together with a conventional internal fixator at the same time, and the fixation plate 1 and the conventional internal f...

Abstract

The invention provides an inside support structure for a medullary cavity suitable for strengthening internal fixation for a proximal femoral fracture. The inside support structure comprises a fixingplate, wherein at least two screw holes are formed in the fixing plate and are in a design of locking screw holes; the fixing plate is arranged inside a femoral medullary cavity and is attached to theinner side surface of a thigh bone; the fixing plate is fixed on the thigh bone through screws screwed in the screw holes; the inner side surface is one surface close to the inside of a human thigh;and unicortical or biocortical fixation can be carried out on medial cortex of the thigh bone. The problems that existing internal fixation for the proximal femoral fracture is insufficient in strength and poor in stability are solved. The inside support structure for the medullary cavity belongs to the technical field of intertrochanteric fracture repair.

Description

technical field [0001] The invention provides an inner medullary cavity support structure suitable for strengthening the internal fixation of proximal femur fractures, and belongs to the technical field of fracture repair. Background technique [0002] At present, fractures of the proximal femur (femoral neck and trochanter) are generally fixed with sleeve plates, intramedullary nails, or hollow screws. These fixation methods have eccentric fixation (such as sleeve plates or hip sliding compression screws), Insufficient stability of the proximal intramedullary nail (PFNA, etc.), the hollow nail is a separate structure, insufficient control of the rotation of the fracture end, and complications such as internal fixation failure often occur, especially for severe or unstable fractures with osteoporosis. need to be addressed. Contents of the invention [0003] The purpose of the present invention is to provide a support structure inside the medullary cavity suitable for inte...
