During 10 years research the author focused on the physiological and anatomical problems stemming from surgical anomalies. He came to the conclusion that it is surely the lack of mathematical precision in ortho paedic surgery that causes orthopaedic handicaps. The author firmly believes that if mathematical deductions were applied to orthopaedic knowledge many immedi ate complications and sequelae could be avoided and people could regain new life in the true sense of the term.
