More particularly, the present invention relates to a bone plate for bone fusion of the fibular bone and a bone plate system including the bone plate, and more particularly, The present invention relates to a bone plate for bonding a bone of a peroneal bone and a bone plate system including the bone plate, which can securely fix the bone to a fracture site accurately and stably and firmly.

In general, the bone plate is a fixation plate used to stabilize the fractured or damaged bone and parts of the weakened bone.

These plates have a configuration in which holes having certain shapes are formed so as to accommodate fixing elements such as a screw for fixing the target portions of the bone.

In particular, the fibula is a long, long bone parallel to the outer side of the tibia (tibia). It is located between the knee and ankle and is one of the bones of the calf. It is called the calf bone and the ankle joint joints). It can cause fractures due to impacts during an accident or exercise, and it can be used to fix fractured bone by securing the plate to the surface of the fibula at the fracture site using a fixing element such as screw. And bone joining.

However, in using the conventional plate, there are inconveniences that the user can not use the fixed elements in various ways and forms by using specific holes of the plate in specific situations, and improvement is required .

In addition, the conventional plate has a certain shape. However, it has a problem that it is difficult to securely fix it on the fractured part of the fibula, and when the user uses the device forcibly, the product is damaged, There is a problem that the treatment and recovery of the patient are affected.
