Problems solved by technology

However, it also exposed many problems in clinical practice. Firstly, it needs to open the knee joint during implantation, which has a certain impact on the function of the knee joint after surgery. Secondly, because the medullary cavity of the distal femur is deconstructed like a bell mouth The implantation of the intramedullary nail cannot achieve good stability. Although the distal locking nail can achieve partial stability, it cannot be fixed because it is fixed on the cancellous bone and is not firmly fixed to the main part. Provide adequate stabilization of the distal femur

Embodiment Construction

[0018] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0019] Such as figure 1 with figure 2 As shown, the bone plate device for distal femur fractures of the present invention includes a bone plate main board 1 and a bone plate sub-plate 2, the overall shape of the bottom side of the bone plate main board 1 is opposite to the anatomical shape of the outer surface of the distal femur. A number of screw holes are provided at both ends of the bottom side and the top side of the bone plate main board 1 .

[0020] The bone plate main board 1 is provided with an arc-shaped protrusion 3 on the bottom surface near the distal end of the femur (i.e., at the bottom side), and a set of temporary screw holes 5 are respectively provided at the front and rear ends of the arc-shaped protrusion 3, two o...

Abstract

The invention discloses a bone fracture plate device for the distal femur fracture. The bone fracture plate device comprises a main bone fracture plate body and an auxiliary bone fracture plate body. An arc-shaped protrusion is arranged at the position, close to the distal femur, of the bottom face of the main bone fracture plate body, multiple temporary screw holes are formed in the front end and the rear end of the arc-shaped protrusion respectively, and grooves are formed in the positions, around the arc-shaped protrusion, of the main bone fracture plate body. The auxiliary bone fracture plate body and the grooves are matched in size, an open groove corresponding to the arc-shaped protrusion is formed in the middle of the auxiliary bone fracture plate body, and screw holes corresponding to the temporary screw holes are formed in the front end and the rear end of the open groove. When the arc-shaped protrusion of the main bone fracture plate body is inserted into a positioning groove of the auxiliary bone fracture plate body, the auxiliary bone fracture plate body is embedded into the grooves of the main bone fracture plate body, and meanwhile the temporary screw holes correspond to the screw holes. Stable and firm fixation can be achieved, and eccentric fixation and bone nonunion are effectively avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, and is an implant device for treating distal femur fractures, in particular to a bone plate device for distal femur fractures. Background technique [0002] Minimally invasive plate osteosynthesis (MIPO) is a modern fracture fixation technique, which uses a simple fracture reduction technique and uses non-compressive plate fixation to maintain fracture alignment, minimizing surgical exposure and soft tissue stripping , improve fracture healing rate. At present, there are generally several methods for the treatment of distal femoral fractures: the first is the anatomical bone plate of the distal femur, which is an earlier internal fixation implant, and its characteristic is that the The anatomical shape of the first type is very convenient for clinical use, but there is no "locking" design between the screw and the plate; the second type is the distal femoral anatomical locking plate, which is th...
