Background

Fracture refers to a disease of partial or complete fracture of bone due to trauma or pathology, and its main clinical manifestations are: the fracture has localized pain and tenderness, local swelling and ecchymosis, partial or complete loss of limb function, and complete fracture with limb deformity and abnormal activity. After the fracture occurs, proper fixation is important, otherwise, the injury can be more seriously injured and even threaten the life of the injury. The fixing splint is a product used for compression, fixation or support when a bone part of a human body is completely fractured or simply fractured (sprain, contusion, ligament injury).

The fracture of children is also rare due to the fact that the bones of children are in a rapid development stage and are fragile. When the limb of the child is fractured, the subsequent treatment of fracture reduction is carried out by the fixing splint for pediatric orthopedics, so that the fractured end is quickly healed under the relatively static condition. However, although the existing fixing splint for pediatric orthopedics can fix the fractured end, the following defects generally exist:
