Donald
DeFeo

Dr. Don R. DeFeo advanced the healing arts in Orange County for over 40 years.

Dr. Donald R. DeFeo was one of the early adopters of a cutting-edge technique, called microsurgical discectomy, for operating on ruptured spinal discs, which was pioneered in the 1970s. A graduate of the University of California, Irvine, Donald DeFeo became one of the most prominent neurosurgeons in the Orange County area. He performed nearly 200 microsurgical discectomies each year, making Chapman Medical Center one of the leading hospitals in the state of California for back surgery as evidence by the results of a California state study regarding complications of surgery.

An earlier surgical method for treating ruptured discs is called open discectomy. In this procedure the muscle tissue overlaying the spine must be cut back in order to expose the herniated disc, which is then dissected to relieve pressure on nerves that branch out from the spine. The method used by Dr. Donald R. DeFeo required a much smaller incision that went through the muscles down to the site of the injury. Working in much tighter quarters, Dr. Donald DeFeo removed the protruding disk herniation or, in some cases, bone. With the pressure removed, patients experienced an immediate reduction or elimination of pain. This minimally invasive technique allowed patients get up and move around and get back to their normal lives much sooner.

Dr. Donald R. DeFeo served as an Assistant Professor at the University of California, Irvine School of Medicine and an Attending Neurosurgeon at UC Irvine beginning in 1975. In addition to his practice, he found time to publish papers on aspects of Neurology and Neurosurgery, as well as attended numerous conferences and seminars where he kept up to date on the latest developments in his field.

  • Marco Island, Florida, Dr. Donald R. DeFeo
    December, 2010

    Dr. Donald R. DeFeo resides in Marco Island, Florida, which is located in Collier County, not far from the city of Naples. Boasting more than 100 miles of waterways and 6 miles of beaches, Marco Island spans only 24 square miles nestled in the attractive Gulf of Mexico. As the largest Barrier Island in Southwest Florida’s Ten Thousand Islands, Marco Island has a permanent population of 15,000 and reaches a peak of 35,000 during winter months. The Calusa Indians were the first known inhabitants of Marco Island. Most likely descendants of the Mayans, these settlers may have reached the area as early as 2,000 BC. Later, when Spanish conquistadors began to arrive in the region, relations between the conquistadors and the natives were consistently hostile. Many Spanish explorers were ambushed as they attempted to bring their boats ashore, and the famous conquistador Juan Ponce de Leon y Figueroa was killed by a Calusa spear in 1521. However, diseases spread by Spanish explorers and others from Europe ultimately decimated the Calusa people, and their civilization vanished by the middle of the 18th century. Seminole Indians later took the place of the Calusa Indians, and American pioneers subsequently followed. Braving mosquito-infested swamps, these fisherman, hunters, and farmers began settling what would ultimately become Florida’s Marco Island. Though well-cultivated plantations were developed as early as 1824, the settler William Thomas Collier officially established Marco Island when he arrived in 1870. Marco Island was originally incorporated as Collier City in 1927. The first Spanish explorers named the island “Caxymbas.” Indian for “fresh water,” this place name remains one of the oldest in North America. The island later changed its name to La Isla de San Marco, which later became San Marco Island, and finally Marco Island.

  • The Congress of Neurological Surgeons, Dr. Donald R. DeFeo
    February, 2011
    Possessing approximately 40 years of professional experience, Dr. Donald R. DeFeo, a highly regarded neurosurgeon and was an Assistant Clinical Professor of Neurosurgery at the University of California, Irvine, networks and collaborates with physicians and surgeons around the world as a member of several Medical Academic Institutions.

    Dr. DeFeo actively participates in the American Association of Neurological Surgeons, the American College of Surgeons, the Western Neurosurgical Society, and the Congress of Neurological Surgeons, the latter of which advances neurosurgical research and standards of care on a global scale. Counting more than 7,000 neurosurgeons around the world among its members, the Congress of Neurological Surgeons seeks to develop pioneering educational programs, promote clinical- and scientific-based practices, and publicly advocate for improved safety and quality of neurosurgical practices. The congress maintains strong ties with similarly committed groups, like the American Board of Neurological Surgery, the Foundation for International Education in Neurological Surgery, and Women in Neurosurgery.

    Established in St. Louis, Missouri, in 1951, the Congress of Neurological Surgeons grew out of a need to provide advanced training to the many neurosurgeons returning home from World War II. Holding its first meeting in Memphis, Tennessee, the trade group started out with 121 member physicians. Today, the Congress of Neurological Surgeons remains true to its ultimate mission of improving the field of health worldwide by creating new opportunities in medical education, scientific exchange, and research. For its current members, the Congress of Neurological Surgeons offers a variety of benefits, including subscriptions to respected journals in the field of neuroscience like NEUROSURGERY and Operative Neurosurgery, a quarterly supplement.

    The Congress of Neurological Surgeons University of Neurosurgery maintains a comprehensive offering of continuing education courses available as webinars, online videos, podcasts, and other forms. The congress also provides neurosurgeons with a voice in legislation through its public policy and advocacy groups, which include the Council of State Neurological Societies and the American Association of Neurological Surgeons/Congress of Neurological Surgeons Washington Committee.
