The aim of our study was to compare two groups of patients with pertrochanteric femoral fracture types 31 A1 A2 A3 according to the AO who were treated with two different types of implants. The first group of 54 consecutive patients with above mentioned types of femoral fractures were treated using Proximal reconstruction nail manufacturer Beznoska comp., which is a standard implant we have been using for two years. The second group of 33 patients were treated with a new implant PCCP (Percutaneous Compression Plate) manufacturer Orthofix. We evaluated the time of operation, total blood loss (hgb, htc, number of blood transfusions), peri- and postoperative complications and subjective feeling of pain using the VAS (Visual Analogous Scale). The patients were at the time of procedure and after one year follow-up. The operation time of the standard and new techniques were comparable. The miniinvasive technique of PCCP was accompanied with significantly lower blood loss and significantly lower intensity of pain after the procedure. There was no difference in number of complications. One-year follow-up assessment showed greater mortality in the patients treated by the standard Proximal reconstruction nail (Beznoska CR).
