[WorldKings – World Almanac Event 2023] 11th anniversary of the establishment of World Pediatric Bone and Joint Day (October 19, 2012 – October 12, 2023)


(worldkings.org) The Pediatric Specialty Group established the first World Pediatric Bone and Joint Day on October 19th, 2012. The day is held in conjunction with Bone and Joint Action Week.

While the first Pediatric Bone and Joint Day — or PB&J Day — wasn’t celebrated until 2012, orthopedic medicine has far longer roots. Originally, the term “orthopedic” referred specifically to the correction of musculoskeletal deformities in children. Nicolas Andry, who was a professor of medicine at the University of Paris, coined the term in his textbook published in 1741. This book, which was directed towards parents, advocated for exercise, manipulation, and splinting to treat child bone deformities. 40 years later, In 1780, Jean-Andre Venel opened the first orthopedic institute, which was dedicated to treating children’s skeletal deformities.



The modern hip replacement was introduced in the 1960s by English tribologist Sir John Charnley, who made the connection that implants can be used to replace joint surfaces. He designed a one piece stainless steel femoral stem & head and an acetabular component, both of which were used to fix the bone along with bone cement. The Charnley Low Friction Arthroplasty and designs that evolved from it were used for over two decades for hip replacement procedures. In the 1970s knee replacements, using similar technology, commenced for patients with rheumatoid arthritis.



USSR doctor, Gavril Abramovich Ilizarov, made a major contribution to orthopedic procedures without much training in the specialized field. Sent to look after Russian soldiers in 1950s Siberia, he came face to face with crippling conditions, infections, and bone malalignments. Employing the assistance of a nearby bicycle shop, he invented external ring fixators, similar to the spokes on a bike. With this, he was able to heal, realign, and lengthen to an unprecedented degree. The Ilizarov appartus is still used by surgeons to this day.
