Design and Application of Elbow Brace for Children Cubitus Varus

Objective To design a kind of elbow brace whose rolling center was made from nylon 66 material for children cubitus varus. The elbow brace which can be be penetrated by X-ray was suitable for the prophylactic treatment of children humerus fracture complicated with cubitus varus. Methods According to the occurrence mechanism of cubitus varus and children's pathogenesis, key points including the camber angle, the fracture end pressure method and relative scope between the upper arm and cubitus of the elbow brace were designed innovatively. Then 3D drawing and engineering drawing of the elbow brace were made through solidworks 3D software. Results The broken ends of fractured bones can be observed clearly through the nylon mainboard of the elbow brace which can be closely combined with patients' arms without discomfort. Thus the cubitus varus can be prevented with the elbow brace. Conclusion The elbow brace with significant treatment effi cacy is worth to be promoted.
