Selective rickets from localized advanced maturation—a case report

Abstract

An unusual cause of rickets is illustrated by a patient with infantile multisystem inflammatory disease who, by age 2 years and 4 months, developed striking radiographic and clinical rickets restricted to those joints involved by the inflammatory process. The locally increased vascularity from his inflammation led to increased maturation at those sites so rapid as to override the usual enchondral calcification, thus causing a rickets pattern. Other sites, such as the proximal humeri, lacking any inflammation, showed no increased maturation rate and did not manifest local rickets. Rapid local bone maturation may cause localized rickets.
