Ergebnisse der Versorgung pertrochantärer Frakturen mit dem PFNA
Common factors such as the ageing population and the high incidence of osteoporosis in elderly people result in a high prevalence of per- and subtrochanteric femur fractures nowadays. The correct treatment strategy of these fractures is important because they represent a major health risk for elderly patients and high costs for the health system. The current study was undertaken to evaluate the use and outcome of the PFNA of Synthes® over a period of 5 years in our hospital. We analysed the hospital database and completed the follow up by telephone interviews using a standardised questionnaire. In total we included 437 patients who were operated with the PFNA between December 2004 and December 2009. A total number of 293 (67 %) patients were available for the outcome analysis. 55 (21,6 %) of the patients died within the first postoperative year. Intraoperative complications were found in 7 cases. During the follow-up period in total 29 % of the patients suffered from postoperative complications. The most frequent mechanical failure of the PFNA consisted in lateral dislocation of the blade which occured in 17 cases and which was revised in 16 cases, whereas the intensively discussed cutting out of the blade was only observed in 6 cases. The PFNA is a useful implant in the treatment of per- and subtrochanteric femur fractures.
