During World War I, Bayumi, who was studying in England, worked as a civilian contract surgeon in the Welsh Metropolitan War Hospital in Cardiff. In his memoirs, the American orthopaedic surgeon H. Winnett Orr described Bayumi as a "fine worker". Bayumi and a fellow civilian Portuguese surgeon were assigned as assistants to two British surgeons and each had charge of two wards of about fifty beds each.
Back to Egypt, he was assigned professor of surgery in the Egyptian University. In 1938 he established Kasr El Aini Orthopaedic Surgery Department, the oldest department dedicated for orthopaedic surgery in Egypt and the Middle East, with Professor Mohamed Kamel Hussein.
