Nutritional rickets: report of four cases diagnosed at orthopaedic evaluation.
Nutritional rickets, the classic form of vitamin D-deficiency rickets, is rarely seen in the setting of modern medicine. We report four cases of nutritional rickets diagnosed at the time of orthopedic evaluation at our institutions during a 3-year period. All patients were referred by their pediatricians for evaluation of bowlegs. All children lived in a northern climate. Three were black and one was white. Prolonged breast-feeding and an unusual diet were identified as the underlying cause in our cases. Genu varum, seen in the setting of relative short stature and low weight, with a consistent social history, should raise the suspicion for nutritional rickets. The continued prevalence of this disease entity must be recognized in both the primary care and the orthopedic surgery setting. Vitamin D supplementation and enhanced sunlight exposure serve as effective prophylaxis and treatment of this disease.
