Radio-ulnar synostosis in Williams syndrome. A frequently associated anomaly

Pediatr Radiol. 1991;21(7):508-10. doi: 10.1007/BF02011725.

Abstract

Limitation of supination and pronation of the forearm has been occasionally described in individuals with Williams syndrome. It was found in 26% of 23 subjects examined, and was associated with a spectrum of severity of radio-ulnar synostosis on radiography. The occurrence of this functional motor impairment in a substantial subset of persons with Williams syndrome is relevant, because its evaluation is important in habilitation planning.
