摘要： Provided is an orthopedic implanted screw. The orthopedic implanted screw may include a fixed seat and a screw body. The fixed seat may include a seat body, a deformation limiting portion and a taper portion. Herein, the seat body is provided with a limiting cavity, a top avoiding opening and a bottom avoiding opening, the deformation limiting portion is provided on an inner wall surface of the seat body, and the taper portion is provided on an outer wall surface of the seat body. The screw body is detachably mounted on the fixed seat, the screw body being configured to drill into a bone in a rotating mode, a part of the screw body is limited in the limiting cavity, another part of the screw body drills into the bone after passing through the bottom avoiding opening, and the screw body positioned in the limiting cavity abuts against the inner wall surface of the seat body so that the taper portion may drills into the bone, to accordingly prevent the screw body from dropping out of the bone. The disclosure solves the problem that a bone screw in the conventional art may easily get loose or screw out from the bone after working in presence of a complicated stress for a long time, accordingly it is not only unfavorable to quick and stable growth and healing of the bone but may cause secondary damage of an affected area, and consequently living quality of a patient may be influenced seriously.
