The aim of this study was to investigate whether growth factors essential for fracture healing are released in the immediate aftermath following fracture and whether reaming of IM cavity causes increased liberation of these autocoids. Consecutive adult patients with femoral shaft fractures forming two groups (a group who received unreamed nail (n=10) and a second group who received reamed nail (n=10) were recruited for this study. Peripheral blood samples and samples from the femoral canal before and after reaming and before and after the solid nail insertion were collected. Serum was extracted and using Elisa colorimetric assays the concentration of Platelet Derived Growth Factor (PDGF), Vascular Endothelial Growth Factor (VEGF), Insulin-like Growth Factor I (IGF-I) Transforming Growth Factor beta 1 (TGF-21) and BMP-2 levels was measured.Purpose
