A retrospective study on 52 Legg-Calvé-Perthes disease patients was performed, with the objective of identifying the initial characteristics of the patients according to registration files data, such as: clinical status, radiographic classification and physical examination. The outcomes noted were as follows: 22 patients (42%) reported the presence of pain and limping, 21 patients (40%) reported only pain, 2 patients (4%) reported only limping, and 7 patients (14%) reported no pain or limping. During evaluation for range of motion, we found the numerical description for 16 (31%) patients, 28 (54%) patients the decrease in the range of motion was just described, but no numerical value assigned, and in 8 patients (15%) such decrease - either with or without numerical value - was not reported. Regarding the radiological picture, we found that Catterall classification was used most of the times (64%), followed by Salter-Thompson (27%) and Herring (9%). We concluded that the baseline clinical status of these patients is similar to what is found in literature, with pain, limping, and decreased range of motion of the hip involved. Catterall's is the radiographic classification mostly used.
