Clinical case of Blount's disease and its differential diagnosis

Abstract

Lower extremities deformation is observed quite often in infants. One of the Blount's disease diagnosis features is the difficulty of its differential diagnosis of when excluded from other conditions such as rickets, rickets-like diseases and physiological curvature of the lower extremities in infants. Article represents the main diagnostic criteria for the abovementioned diseases. A clinical case of a patient with Blount's disease who had deviations in calcium-phosphorus metabolism that in their turn are uncommon for this pathology is described. The entire set of clinical and laboratory signs analysis was carried out in details, which then made it possible to carry out a differential diagnosis and exclude hereditary forms of rickets, primarily hypophosphatemic rickets as the reason for pronounced varus deformity of the legs in a 2.5 y/o pediatric patient. The tactics for further treatment by a specialized practitioner had been determined as well.
