Tree of Andry freed of its tether as a metaphor for increased diversity in Orthopaedics.

​

The Tree of Andry has been the traditional symbol of orthopaedics for hundreds of years.  

​

French doctor, Nicolas Andry, first coined the word orthopaedie in his 1741 book “Orthopaedie” which discussed the prevention and correction of deformities of the spine and bones of children. The word "orthopedie" is derived from the Greek words for straight (“orthos”) and child (“-paideia”). The cover of Andry's book was engraved with the image of the crooked sapling tied to the stake which has become known as the “Tree of Andry.”
