摘要: The relationships between bone mineral content (BMC), calcium, and strength were studied in fractionally demineralized feline femurs. In 44 pairs of cat femurs, the right bones decalcified ethylene diaminetetra acetic acid (EDTA) to 20%, 40%, 60%, 80%, 100% intact left (= control). then loaded failure, maximum values recorded. data used calculate percentage relative A correlation coefficient (r) 0.970 was found decalcification bending strength. direct relationship (r = 0.876) also observed total calcium extracted loss BMC. EDTA solutions spot checked for protein determine if organic matrices had been altered by demineralization. Protein never detected. Nor did tissues display histologic evidence gross microscopic damage. This study has shown that 20% led about 35% strength, 60% caused 75% These are significant as they highlight importance osteopenic bone.
