Osteoporosis is an insidious illness that sneaks up on you. The early bone density machines in the 1970's and early 1980's all used different kinds of units, so results were reported in Z-scores to allow comparisons to normal people. The reference ranges are also problematic. Cattle have two hooves leading to the distinctive double cotton reel at the distal end whilst the horses only display a single cotton reel because of the single hoof. Mayo Clinic; 2017. These minerals, primarily calcium and phosphorous, make up 65% of bone tissue and are what give bone its hardness and rigidity. If teeth are available then identification is much easier, with teeth of the two species (particularly molars) being very different. The lower bone density test results, the lower your total bone density, indicating osteopenia or osteoporosis. Table of Densities of Common Substances - ThoughtCo Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging. . For bone density, the Z-score will tell you if the bone density is close to the average value for the person's characteristics such as age, race and gender, but that still does not tell you if the bone is strong. An athlete has greater bone density than a couch potato. Summary Plant foods are rich in many important micronutrients that are beneficial for bone health. As one can see horse teeth are much squarer in profile and plan compared to cattle teeth with a radically different enamel fold pattern. Old Ephraim. For example, DEXA of the hip has a relative risk of about 2.5 for each standard deviation for predicting hip fracture; therefore, a person with a z-score of -1 has 2.5 times the chance of a hip fracture compared to a woman with Z-score of zero (average). The "ash fraction" value is the key here. Specific Weight and Specific Gravity - An introduction to density, specific weight and specific gravity. The NIH Osteoporosis and Related Bone Diseases ~ National Resource Center provides patients, health professionals, and the public with an important link to resources and information on metabolic bone diseases. In other words, a normal Z-score only indicates that the bone density is comparable to that of others of the same age, sex, and body size.
