In current issue of "Progress in Medicine” we included a commemoration of professor Adam Gruca, one of the 20th century's most famous orthopaedic surgeons.

His student and author of the commemoration, professor Stefan Malawski, is an established authority among orthopaedic surgeons in Poland and abroad.

The majority of topics in the current issue of "Progress in Medicine”, was also the subject of clinical and scientific activity of professor Jan Orłowski, the first and many years' Head of the Department of Orthopaedics and Traumatology the Medical Centre of Postgraduate Education, Warsaw, Otwock. Professor retired at the end of September 2006, unfortunately two years later, 09.19.2008, our, as we called him, Professor passed away. His experience, kindness and modesty had a great influence on the development of the Department. Professor had an exquisite trauma intuition, he devoted his professional life to improvement of ostheosynthesis and treatment of the knee joint trauma. His idea was to treat the fractures in a way which would be least invasive and at the same time stable enough to allow early mobilization after the surgery. These conditions are fulfilled by intramedullary nailing, the method first used to treat femur fractures by professor Küntscher. The German surgeon also blocked the nail for the first time. The idea of intramedullary nailing blocking was later popularized by German orthopaedic surgeons, professor Gross and Kempf. At the moment it is the most popular method of ostheosynthesis of the long bones, especially femur, tibia and humerus. It is used for fracture treatment, as well as for treatment of delayed union and non-union. It is well recognized method of multilevel and multilocal fracture treatment.
