A Pre-operation AP/Lateral X-Ray of the right elbow from the first patient showing displacement and comminution of the radial head. Fig. 1B Post-operation AP/Lateral X-Ray of the right elbow from the same patient. The injury was treated with radial head arthroplasty. Fig. 1C-F Active ROM evaluation of the same patient; elbow flexion of 110 ; elbow extension of 10 ; elbow supination of 85 ; elbow pronation of 75 .

The first patient is a 35 years old male, with surgery due to close fracture of right radial head after fall from 10 m height (Fig. 1A). Later on, the patient's right elbow and left knee was operated in February 2018 (Fig. 1B).
A Pre-operation AP/Lateral X-ray of the left elbow from the second patient before closed reduction was performed. The elbow was dislocated and the radial head was fractured. Thus, it is Mason type IV injury. Fig. 2B AP/Lateral X-ray of the left elbow from the same patient after closed reduction and application of posterior slab. Fig. 2C Post-operation AP/Lateral X-ray of the left elbow from the same patient. This patient was managed with prosthetic replacement of the radial head. Fig. 2D-G Active ROM evaluation of the same patient; elbow flexion of 140 ; elbow extension of 5 ; elbow supination of 80 ; elbow pronation of 70 .

The second patient is a 53 years old female with close fracture dislocation of left elbow after fall on an outstretched hand in a volleyball game (Fig. 2A and B). Her left elbow was operated in December 2018 (Fig. 2C). From the second patient, active ROM of elbow flexion was 140  (Fig. 2D), extension was 5  (Fig. 2E), supination was 80 , pronation was 70 , while passive ROM of elbow flexion was 140 , extension was 0 , supination was 85  pronation was 75 .
A Pre-operation AP/Lateral X-Ray of the left elbow from the third patient. The radial head was displaced >2 mm and conservative treatment would likely to fail, so the patient undergo surgery. Fig. 3B Post-operation AP/Lateral X-Ray of the left elbow from the same patient. The patient was also treated with radial head arthroplasty. Fig. 3C-F Active ROM evaluation of the same patient; elbow flexion of 80 ; elbow extension of 10 ; elbow supination of 80 ; elbow pronation of 20 .
