During the First World War, the interest in children's orthopedics disappeared. The pediatric surgeons at the front preferred conservative treatment for amputations. François Calot (1861-1944), surgeon at l'hopital Berck, invented the term 'orthopedic war operation'.
In 1918, the French Society for Orthopedic and Traumatological Surgery (SOFCOT) was established for the promotion and development of knowledge in this surgical specialty. She set out to improve the functional status of patients and to improve them after a trauma or a disorder of the musculoskeletal system.
SOFCOT collected more than 3000 specialized surgeons and was divided into three sectors:
The beautiful work 'Masseuse' by French artist Edgar Degas (1834-1917) that can be admired in the Musée d'Orsay in Paris.
In the article 'Angina pectoris: changes in electrocardiogram during paroxysm' that appeared in the Lancet, British physician George Bousfield (1894-1974) described the spontaneous ST depression in an electrocardiogram during angina.
