The tensile deformation characteristics of compact bone from deer antler were measured in both the "dry" and "wet" states and compared with published values for bovine compact bone. The tensile strength in the wet state (108 +/- 5.1 MN/m2) was comparable to the value for bovine compact bone tested at the same strain rate. The modulus values was very low: 7.5 +/- 0.9 GN/m2. The work to fracture was comparatively high, about 3 times that for bovine compact bone. Fractographic examination revealed fibrillar and osteonal shear for samples fractured in the dry state. In the samples tested in the wet state, some regions exhibited pullout of lamellar segments from within a Haversian system. The results are explained in terms of the higher collagen content and lesser degree of mineralization in the antler.
在“干燥”和“湿润”状态下测量了鹿茸密质骨的拉伸变形特性，并与已发表的牛密质骨数值进行了比较。湿润状态下的拉伸强度（108±5.1 MN/m²）与在相同应变率下测试的牛密质骨的值相当。模量值非常低：7.5±0.9 GN/m²。断裂功相对较高，约为牛密质骨的3倍。断口分析显示，干燥状态下断裂的样品存在纤维状和骨单位剪切。在湿润状态下测试的样品中，一些区域呈现出哈弗斯系统内板层段的拔出。根据鹿茸中较高的胶原蛋白含量和较低的矿化程度对结果进行了解释。
