He has co-written (with professor Arthur F. Dalley II) Clinically Oriented Anatomy, which is the most popular English-language anatomy textbook in the world, used by scientists, doctors, physiotherapists and students worldwide. The book is especially popular because of its 'blue boxes' - passages of text on blue background that relate the classical anatomy to real-world concepts in the diagnosis and treatment of human patients. The book has been translated into multiple languages. He also co-wrote (with professor Anne M. R. Agur) Essential Clinical Anatomy.
