An Unusual Association of the Windblown Hand with upper Limb Hypertrophy

Abstract

An eight-year-old boy presented with a congenital windblown hand deformity associated with partial hypertrophy of that arm. Many of the classical features of the windblown hand syndrome described in previous papers were absent. In this case, the primary cause of the ulnar-drift deformity was an anomalous epiphysis at the base of the second metacarpal. Surgical correction was readily obtained by osteotomy at the base of the metacarpal combined with soft tissue re-alignment.
