We review our radiographic experience with hypertrophic osteoarthropathy. Soft tissue abnormalities such as finger clubbing, "elephant feet" and cutis verticis gyrata are well appreciated by plain radiography. ⋯ Radiographic signs of inflammatory arthropathy are conspicuously absent. Periosteal proliferation is an orderly evolving process in 3 dimensions: in the number of affected bones, in the area of involvement of a given bone and in the shape of periostitis.
