Clavicle plate and clavicular plate group

The present invention is a clavicular plate group, especially a clavicle plate for fixing a clavicle and a plurality of bone nails.

When a human body is fractured, different treatments are given according to the location and severity of the fracture. In addition to bed rest, drug pain relief, calcium supplementation, vitamins or hormone supplementation, bone plates and bone nails are commonly used to treat fractures. Methods.

Clavicular fracture is one of the common fractures of the upper extremity. The most common cause is the external force directly hitting the clavicle to produce a fracture, or the palm of the hand when the child is falling. After the force is transmitted, the clavicle cannot support and fracture. The lateral part of the clavicle is due to the gravity of the upper limb. And traction of the pectoralis major muscle, and shifting forward and downward. Since the medial end of the clavicle is connected to the sternum, the lateral end is connected to the scapula, so the clavicle often moves when the human body moves. Because of this characteristic, the fixation of the clavicular bone plate used after the treatment of the clavicular fracture is the main reason for the recovery time and recovery.

In the prior art, the clavicular bone plate is directly locked on the diaphysis, and in order to firmly lock the screw on the clavicular bone plate, the design of the clavicle bone plate has to be gentle, but the curvature of the surface of the backbone is greatly changed. The patient is quite uncomfortable after implanting the clavicle plate. In addition, because the curvature of the clavicular bone plate is relatively flat due to the curvature of the backbone, the doctor usually does not have a relatively stable positioning point when implanting the clavicular bone plate, which causes the position of the clavicle to be warped, and is more likely to occur when the patient is active. A situation in which a dislocation phenomenon is caused by a dislocation of the fracture complex or a secondary fracture of the clavicle that has not yet fully recovered.

In view of the fact that the prior art clavicle plate design is relatively gentle, the patient is quite uncomfortable after implanting the clavicular bone plate, and the prior art clavicle plate has no stable fixing points, etc., the purpose of the present invention is to provide a clavicle plate and a clavicle.
