Scheuermann's kyphosis in adolescents is relatively uncommon, with studies showing a wide but still modest range in how many youths are affected. The range around 0.4% to 8.3% best captures the typical variability across populations and diagnostic methods (from strict radiographic criteria to broader screening). That breadth reflects how some studies identify only clear wedging deformities, while others include milder cases or different age groups. The other ranges are generally too high or too low compared with most epidemiologic data, which is why the 0.4% to 8.3% range is the best fit.
