To use the roentgen sign method of recognizing abnormal radiographic findings effectively, an understanding of normal radiographic anatomy for the specific area of interest is necessary. The purpose of this chapter is to provide a limited reference for the radiographic anatomy of the appendicular skeleton. Refer to comprehensive textbooks on radiographic anatomy for more detailed information.1–3 The radiographic nomenclature used in this chapter was approved by the American College of Veterinary Radiology in 1983.4 Some equine images in this chapter (Figs. 13-30 through 13-49 and 13-54 through 13-57) have been taken from previous publications and are reproduced here with permission of the journals and author.5–7
