In 1830, after years of research and development, Heine presented a medical tool to his colleagues. It was a "bone saw", which he called the "osteotome", and which revolutionized surgical treatment. His invention was a great success among medical experts all over Europe. Heine travelled to other parts of Germany, and to France and Russia to present it to other surgeons. In 1836 a doctoral thesis on the "Osteotome and its application" was published in
Munich. Heine declined an offer of the Russian Tsar
Nicholas I to take over the position of an orthopaedic senior consultant at the imperial school in
Kronstadt and returned to Würzburg. The University of Würzburg awarded him an honorary doctorate in 1836 and an honorary professorship in 1838, although he had never acquired any degree. == Research work on bone formation ==
