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.
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. If necessary they accomplish the tensionless closure of the wound by means of individual incision planning and the preservation (rotation and sliding) of the intact skin of the breast, which is the precondition of the reconstruction that might be performed subsequently. In the course of the follow-up of 295 operations carried out in this manner excellent or good results were obtained in 83% as far as aesthetics and functionality were concerned. Lymphedema did not develop in a single case on account of operation technique.
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. Its particular advantages are the chance to perform the operation closed, a short operating time and period in hospital, early weight bearing and a simple surgical technique without the need for special instrumentation, requiring little radiographic exposure during surgery. The ideal and relative indications for the application of the technique are discussed. Biomechanical tests have confirmed that the finned medullary nail is the most stable method of fixation of the fractures when compared with other alternative devices.
