Leg bowing in rickets

The most frequent and typical presentation of rickets is bowing of the long bones, especially leg bowing. Bowing of the bone manifests from the age of 6 months. In those patients, pediatricians and/or orthopedic surgeons are often the first specialists that are consulted. As a certain degree of leg bowing in toddlers is considered physiological, the first consultation may not always lead to a diagnostic work-up and therefore diagnosis is delayed until symptoms worsen.  Diagnosis is generally based on blood tests finding low serum phosphorus, and a high or normal alkaline phosphatase together with X-rays.
