Geoffrey John Sadow was born on 22 January 1930 in Cricklewood, London. His father, Alexander Sadow, was an accountant and his mother was Anne née Wildman. Their only child, he suffered a freak accident when playing football at the age of seven. Without suitable medication, he suffered septicaemia and bone infections for which the only treatment was surgical drainage and complete bed rest. He attended Colet Court Preparatory School and, in spite of missing five years of his education due to numerous operations, managed to gain a place at St Paul’s in 1944. Having been left with a severe limp, he cycled to get speedily to distant class venues. Sadly his father died of cancer when he was 13. He studied medicine at University College London and graduated MB, BS in 1954. Before passing the college fellowship in 1962, he spent some time with the Canadian Red Cross. He worked as an orthopaedic registrar with the Royal Free Hospital in 1962 and moved to the Windsor group of hospitals the following year. From 1969 to 1972 he was senior orthopaedic registrar at St George’s and the Rowley Bristow Hospital in Pyrford. During these years he acknowledged the help and advice of various orthopaedic surgeons, including George Philip Arden, George Charles Lloyd-Roberts, Peter Reginald French, Alan Graham Apley and Gordon Hadfield. In 1973 he was appointed consultant orthopaedic surgeon to the Royal Victoria Hospital, Kingston and also worked in private practice in Harley Street. Having suffered throughout his life with pain from his own orthopaedic trauma, he was especially empathetic to his patients and considerate of their needs. He was a fellow of the Royal Society of Medicine and a member of the British Orthopaedic Association. In 1963 he married Janet née Foreman and they had a daughter. The marriage was dissolved and, in 1970, he married Daphne née Wenzerul. A lover of classical music (especially chamber music), fine wine and antique clocks, he indulged a passion for horse racing by acting as a consultant in cases of jockey injury. With his second wife he travelled extensively and they shared a devotion to the Jewish way of life and their local Synagogue. He died in May 2019 aged 89 and was survived by his daughter, stepdaughter and grandchildren.
