AB Pertrochanteric fractures are a rising major health-care problem in the elderly and their operativestabilisation techniques are still under discussion. Furthermore, complications like cut-out are reportedto be high and implant failure often is associated with poor bone quality. The PFNA1 with perforatedblade offers a possibility for standardised cement augmentation using a polymethylmethacrylate(PMMA) cement which is injected through the perforated blade to enlarge the load-bearing surface andto diminish the stresses on the trabecular bone. The current prospective multicentre study wasundertaken to evaluate the technical performance and the early clinical results of this new device.In nine European clinics, 59 patients (45 female, mean age 84.5 years) suffering from an osteoporoticpertrochanteric fracture (Arbeitsgemeinschaft fu¨ r Osteosynthesefragen, AO-31) were treated with theaugmented PFNA1. Primary objectives were assessment of operative and postoperative complications,whereas activities of daily living, pain, mobility and radiologic parameters, such as cement distributionaround the blade and the cortical thickness index, were secondary objectives.The mean follow-up time was 4 months where we observed callus healing in all cases. The surgicalcomplication rate was 3.4% with no complication related to the cement augmentation. More than onehalfof the patients reached their prefracture mobility level within the study period. A mean volume of4.2 ml of cement was injected. We did not find any cut-out, cut through, unexpected blade migration,implant loosening or implant breakage within the study period.Our findings lead us to conclude that the standardised cement augmentation using the perforatedblade for pertrochanteric fracture fixation enhances the implant anchorage within the head–neckfragment and leads to good functional results.
