After his discharge, he returned to Jefferson, joining their Department of Orthopedic Surgery and later being promoted to department chair and third James Edwards Professor of Orthopedic Surgery in 1950, succeeding James R. Martin in the role.[3][4] During his time there, he established a Ph.D in anatomy,[1] worked in an off-campus private practice,[4] established an orthopedic research department,[1] and wrote over 70 manuscripts and five acclaimed medical textbooks – Surgery of the Shoulder (1950, three editions), Diseases of the Knee (1954), Degenerative Changes in the Sternoclavicular and Acromioclavicular Joints in Various Decades (1957), The Management of Fractures and Dislocations (1959, two editions), and The Intervertebral Disc (1970, co-authored with Richard H. Rothman)[4] – which have been translated into several other languages.[1][3] He established the orthopedic journal Clinical Orthopaedics and Related Research, for which he was the editor-in-chief from 1953 to 1966,[2][1] and taught overseas in the Dominican Republic in 1957, Japan in 1961, and in South Vietnam in 1962 during the Vietnam War.[3] He retired from Jefferson the first time in 1970 and moved to Pompano Beach, Florida, but was invited by the University of Medicine and Dentistry of New Jersey to head their new Orthopedic Department in January 1971. He stayed there for five years and trained thirty residents in that time.[2][1] After, he retired again and moved back to Pompano Beach in 1976.[3]
DePalma received numerous honors from Jefferson, including an Alumni Achievement Award and an honorary degree of Doctor of Letters in 1975, and the Dean's Medal of Honor in 1988. Jefferson's class of 1962 commissioned a portrait which hangs in the school, and he is the namesake of an auditorium. Another portrait was commissioned by the Orthopedic Alumni Society of New Jersey in 1988.[1][3]
DePalma came out of retirement ten years later, taking the Florida state medical exam and opening a solo orthopedic practice in Fort Lauderdale in 1977, which he ran until 1983.[2][1][3] The next year, he was rehired by Jefferson to teach orthopedic-radiological sessions for radiology residents, commuting to Philadelphia twice a month and teaching for eight day courses. He retired for the second and final time in January 1989.[1][3]
Personal life and death
DePalma was married twice. His first wife, Vivienne Muti, to whom he was married for 36 years, died in 1997.[3] He was married to his second wife, Gertrude "Trudy" McGowan DePalma, for 34 years, having met her as an operating room nurse in 1953.[1][3] She survived him along with his two sons, Barton and the filmmaker Brian De Palma, and four grandchildren.[3]
He spent his retirement writing several novels, including some medical mysteries, which went unpublished at the time of his death. He did not show his novels to Brian, saying he would "steal my ideas and make them into movies."[1][3]
