At just eight years old, a Vietnamese boy with bone cancer has received a 3D-printed femur — a medical first that has preserved not only his limb but his childhood.
In what is now considered a global first, the child underwent a total femur replacement using a fully customized 3D-printed titanium implant. According to the U.S. National Library of Medicine, all previously documented total femur replacements have relied on traditional implant techniques, with no reported cases involving pediatric patients or 3D-printed, growth-adaptive prostheses.
