Using the method of laser Doppler flowmetry (LDF), 10 healthy boys aged 7 to 9 years and 10 boys of the same age with unilateral hip joint lesion at stage III–IV of Legg — Calve — Perthes disease were examined. In all the examined patients, compared with the healthy subjects, a significant decrease in microcirculation in the hip joint, knee joint and joint of the first toe was found. Prolonged epidural analgesia led to a significant increase in microcirculation in all the examined joints, which indicates the high effectiveness of this method of treating the disease. The LDF method can also be useful for early diagnosis of Legg-Calve-Perthes disease in children.

Key words: Legg — Calve — Perthes disease, treatment, microcirculation, prolonged epidural analgesia.
