The fracture aspects of impact twisted human femurs and tibias have been studied in their wet condition. The main tool used to correlate fracture behaviour with bone structure was the scanning electron microscope. Supplementary data were obtained from macroscopic fracture pattern analyses and stress coat experiments on slowly tested dried bone. The interest of the data reported concerns two major points. Firstly the analysis of the fractographic results leads to the conclusion that the fracture has presumably been initiated by shearing parallel with the torsion axis. The fracture propagates along so called spiral and oblique fracture lines. Secondly, the correlation of the macroscopic fracture pattern with microscopic fracture aspects indicates that the fracture is initiated along the cement lines, which can be considered as the weak matrix in an osteon-cement lining composite. The fracture propagates along the cement lines as well as through osteons and lamellae. Throughout the impact fracture surfaces ductile and brittle fracture aspects were observed, although the brittle fracture mode was predominant during propagation.
