Radiographic images of adults with achondroplasia. A The pelvis shows the same squared shape observed in the early ages, and now the femoral neck is more evident. B In the knees, we can observe the epiphyseal region as broad as metaphysis. Tibiae and fibulae are shorter, however, this last one is longer than the tibiae. C The narrowing of the interpedicular space in the lumbar region is evident in the anteroposterior incidence of the spine X-ray. D In the lateral view of the spine, it can see the concave aspect of the posterior margin of the vertebral bodies. E The hands are short and broad and the ulnar styloid process is prominent
