| Popis: | Fracture healing is a well-organized process between several molecules and mediators. As known from other diseases, genetic polymorphisms may exhibit different expression patterns in these mediators. Concerning fracture healing, this may lead to an extended healing process or non-union. We investigated the incidence of polymorphisms in patients with aseptic non-unions after femoral and tibial shaft fractures as compared to patients with uneventful healing. Exclusion criteria were smoking, diabetes, bilateral fractures, systemic corticoid therapy, and septic non-unions. Analysis of allele frequencies and genotype distribution of various mediators were carried out following PCR. Clinical parameters such as injury severity and in-hospital were analyzed. Fifty patients following non-union (group NU) were enrolled, the control group consisted of 44 patients (group H). A significant association of a PDGF haplotype and non-unions following fracture could be observed. There was a significantly increased in-hospital time and amount of surgical procedures in group NU. Polymorphisms within the PDGF gene seem to be a genetic risk factor for the development of non-unions of the lower extremity following fracture. The early identification of high risk patients could result in an adapted therapeutical strategy and might contribute to a significant decrease of posttraumatic non-unions. © 2011 Orthopaedic Research Society Published by Wiley Periodicals, Inc.
