Professor Maurizio A. Catagni (Italy)

In 1982, after a trip to Kurgan by Dr. Villa and Prof. Catagni from Lecco, the association for the study and application of the Ilizarov method (ASAMI), with president Cattaneo, was founded with the aim of spreading Ilizarov's method in Italy. Since then a spread has begun through congresses and courses attended by many Italian surgeons; since 1984 the method has begun to spread in France, Spain, Portugal, Switzerland, Mexico and Brazil. Meanwhile in Lecco, patients from all over Italy continued to suffer, from difficult-to-resolve diseases, which were treated with excellent results.

Since 1987, after a month-long trip to Canada and 1 month to the United States, visits by North American Orthopedic Surgeons began, and from 1989 began a two-month study program for 2 English-speaking Orthopedics (12 per year ); this program continues today in addition to a program for Orthopedics of the 3rd world that live in the Hospital for free, thanks to the availability of the current Administration. At least 1500 Italian and 2000 foreign doctors attended the Orthopedics Department.

Prof. Catagni takes part every year in numerous Congresses and Courses in various countries, from America to Europe, to the Middle East and the Far East. During these trips demonstrative surgical operations are performed.  Currently there are 27 national ASAMI organisations abroad with a number of members of a few thousand.

Since 1981, approximately 5,000 operations have been carried out using the Ilizarov method on both local patients and those from all over Italy and several from abroad.  For the renowned competence of the regional reference center of the Ilizarov methods of Lecco, the School of Specialization in Orthopedics of the University of Milan has appointed Prof. Catagni for the education of specialists.
