To establish a preventive method against injuries caused by sports, it is necessary to clarify material properties of bone tissues. The object of this study was to examine the effect of formalin preservation on bending characteristic of bovine cortical bone. Samples were taken from plexiform bone in the vicinity of the portion of one-third of the shaft of the femur center. Specimens of the formalin preservation group were prepared in same way as the normal group specimen and preserved in 250 ml of a 10 vol% formaldehyde aqueous solution. The period of formalin preservation was 7 or 30 days. An Instron material testing machine, Model 1000, was used for the bending test and the loading rate was set at 20 mm/min. Formalin preservation did not significantly affect the bending strength. There was an increasing tendency with formalin preservation in bending stiffness.
