The importance of incision-planning and operation technique during organ-preserving and radical operations in the case of patients with mammary cancer.

The authors place a great deal of emphasis on the application of plastic surgery principles in the course of all their operations, especially mammary operations: the incision planning respecting the lines of strength, the atraumatic operation technique (sharp preparation, high-frequency electrocoagulation, tensionless wound closure, and suction drainage from a separate opening). In their organ-preserving operations the radial incision recommended by Veronese is avoided, and the axilla is exposed separately. They do not perform their radical mammary operations according to the customary method (Auchincloss, Patey) either.

The principle and practice of the minimal invasivity in the course of our traumatological work.

The authors examine which experiences can be deduced, in the course of their daily accident surgical work, from the minimal invasive chirurgical treatment of fracture contradicting many times the principles of the chirurgical treatment of fracture standardized by AO International.

A new type of intramedullary nail for the internal fixation of subtrochanteric fractures of the femur.

The Author has developed a modified intramedullary nail for the stabilisation of fractures in the subtrochanteric and proximal one-third of the femur. Due to its three tapered fins the rod fits well into the funnel-like medullary cavity of the proximal femur preventing varus or rotational displacement of the proximal fragment. This method has been applied in 16 cases.
