Four-sided butterfly-shaped steel plate for locking osteoepiphysis of child

The invention provides a four-sided butterfly-shaped steel plate for locking osteoepiphysis of a child. The four-sided butterfly-shaped steel plate comprises a steel plate body shaped like a four-sided butterfly, wherein an included angle is formed between the upper part and the lower part of the steel plate body; 4-6 threaded holes for fixedly connecting screws are uniformly formed in the steel plate body; angles between the screws and the steel plate body are adjustable; a positioning hole and a groove are formed at a symmetrical center of the steel plate body. The included angles are formedbetween the upper part and the lower part of the steel plate body and between the steel plate body and the screws, and by virtue of a rebounding principle of the steel plate body and the screws, theincidence of postoperative complications is reduced and developmental limb malformation is corrected; through design of the steel plate and the screws, a vertical stress generated on the screws duringgrowth of the osteoepiphys
