Dr. Ramon Gustilo, a renowned orthopedic surgeon who revolutionized the treatment of open fractures and mentored doctors from around the world, died after a battle with kidney disease late last year at his home in Eden Prairie. He was 94 years old.
Known as the “father of orthopedics” in his native Philippines, Gustilo came to America in the 1950s to study. After completing a medical residency at the University of Minnesota in 1964, Gustilo became a leading surgeon in his adopted home.
“He was very grateful for what the state and the university had provided him — the opportunity for a poor kid from the Philippines to become one of the most recognized individuals in orthopedic surgery in the last 100 years,” said Marc Swiontkowski, a professor and former chair of the U’s Department of Orthopedic Surgery.
Gustilo is best known for developing a classification system that has helped generations of surgeons assess open fractures — serious wounds where broken bones protrude from the skin.
The Gustilo-Anderson classification, which he and fellow doctor John Anderson published in 1976, provided a standardized way of assessing open fractures and figuring out how to promote healing and prevent infection. The pair came up with the classification after studying hundreds of wounds and tracking what treatments worked and what didn’t.
“It is still the most widely used classification of the severity of open injuries,” Swiontkowski said. “The number of times that article has been cited is in the thousands. There have been efforts to refine it, but his was the pioneering effort.”

Born in 1930 in Manapla, a small city on one of the central Philippines islands, Gustilo survived the Japanese occupation during World War II, an experience that fueled his ambition. During the war, when he was unable to attend school, he tended water buffalo.
While his parents were not poor by Filipino standards — his father had a job as an overseer at a sugar plantation and their family had a house and servants — Gustilo spent his time with the water buffalo dreaming of bigger things.
