a,b. Anteroposterior and lateral X-ray films before operation shows dislocation of left elbow joint, ulnar coronoid process fractures, and radial head fractures; c,d. Three-dimensional CT reconstruction before operation shows dislocation of left elbow joint, comminuted fractures of ulnar coronoid process, and comminuted fractures of radial head; e,f. Anteroposterior and lateral X-ray films were taken after fixation was conducted by applying medial and lateral elbow approaches; g. Three-dimensional CT reconstruction of vertical plane after operation indicates that elbow joint recovers with concentric reduction.
