(a-1) X-ray films one month after removing the device show that the elbow joint alignment is normal, and there are no abnormalities such as dislocation. (a-2) Elbow extension function, elbow flexion function, forearm supination function, forearm pronation function, and good elbow stability one month after removal. (b-1) X-ray films four months after removal show that the elbow joint alignment is normal, and the radial head prosthesis is not loose or falling off. (b-2) Elbow extension function, elbow flexion function, forearm supination function, forearm pronation function, and good elbow stability four months after removal.
