Figure 3

(a) X-ray films of the left elbow show dislocation of the left elbow, comminuted fracture of the radial head, and fracture of the coronoid process. (b-1) X-ray films five days after placement of the device show that the left dislocated elbow has been reduced, the radial head has been replaced, and the device has been placed. (b-2) Active flexion and extension five days after placement. (c-1) X-ray films two months after placement show that the elbow joint alignment is normal, and the device has not become loose, fallen off, or broken. (c-2) Elbow extension function, flexion function, forearm supination function, and forearm pronation function two months after placement.
