Aim. The research of the prevalence, nosological structure, clinical presentations, and pathogenetic features of different forms of coxal epiphyseal pathology including Meyer dysplasia in small children based on the results of clinical and instrumental observation on outpatient orthopedic admission. Material and methods. In 12,000 children from 0 to 5 years, an orthopedic examination was conducted with an assessment of external dysmorphogenetic signs of connective tissue dysplasia, an ultrasonic examination of hip joints, an in-depth X-ray examination. The step-by-step examination algorithm was structured and detailed according to the presence and severity of the coxal region pathology, children’s age. Conclusion. The combination of dysplastic phenotype with joints formation inhibition in children aged 1 year is a predictor of Mayer’s dysplasia and must be the reason for a detailed examination of the hip joints with use of visual diagnostic methods.
