The diagnosis of Meyer dysplasia was confirmed by plain film of the pelvis, a negative bone scan, or normal bone marrow findings on magnetic resonance imaging. The limping resolved without treatment in all patients within 1 to 3 weeks.Conclusions  Meyer dysplasia is a benign condition that should be included in the differential diagnosis of hip disease in infants and children. Awareness of this condition may prevent unnecessary hospitalization and treatment.
