[Nicolas Andry and orthopedics]

The publication of "Orthopédie" by Andry in 1741 promoted a comprehensive approach to children's deformities, introducing both a new word and a twisted tree emblem, which now delineate a modern speciality. A brief appreciation of Andry's book and stormy career focusses on the limitations of his work, which was written for parents. The etymological constraints of orthopaedy are noted, its suggested rivals discussed and the unsatisfactory adaptations of the word in English high-lighted. "Orthopaedics", a deformed adjective used as a noun, and "pediatric orthopaedics" are defective absurdities which could be remedied by a new, accurate and all-embracing noun "orthosurgery".
