The health conditions of human beings were the main concern of medical science. Researchers tried their best and are still working on investigative studies to figure out ways by which they can treat or improve the human health conditions. Health conditions are affected by several ailments and environmental causes. The goal of improving human health conditions requires defining the primary causes of ailments. This investigation will require the invention of accurate diagnostic procedures and devices. Huge amounts of researches and experiments were made to create technical methods that would allow precise diagnoses, whereby abnormal health conditions become treatable. These diagnostic procedures were improved by the sum of scientific researches conducted during the past century. Diagnostic methods should be accurate and precise in such a way to provide us with accurate results by which ailments become definable. Thus, studies are in a continuous and endless search to improve human life conditions and extend life-rate expectancy.<br />Furthermore, the study of human body took two directions that of investigative diagnostic procedures to identify causes and treatments to redeem the human body and mange health issues to eliminate sickness and elevate human health conditions. The second direction is to analyze the autonomy of human physique and simulate its mechanisms in many engineering applications. For instance, from an engineering scientology standpoint, the human body can be viewed as a prefect machine. The design and performance of each part and as a whole unit are beyond our understanding. Every day, the researchers discover and learn from this perfection. For example, many engineering designs simulate human body parts; shoulder in the robot manipulator, neural control system, etc. <br />The engineering mechanics become most obvious within bones structural configuration. They are constructed from living tissue. These bones give the shape of the human body, but this is not the only function of the bones. Bones have several vital functions which are critical for human life. Bones function as the frame around which the human physique is molded, protecting the internal organs, regulating calcium levels which are stored inside the human body (90% of calcium are stored inside the bones), bone morrow produces the red cells, movements, and other vital functions. Such vital functions require quantitative maintenance and monitoring during the various life stages. This monitoring preserves and maintains the physiological health conditions of the bones. Diagnostic procedures will further identify the health conditions of the bone and distinguish between the normality and any abnormality. These procedures were developed throughout the last century and are in constant progress to improve the test results accuracy and data analysis. The results of tests will provide critical information about the bone’s mechanical, physical, and chemical properties. The evaluation of these information will become indicative and will outline the health conditions (diagnosis), treatment procedure, and prediction of future fracture risks.<br /><br />Dr. Ameen M.Al-juboori <br /><br /><br /><br /><br /><br /><br /><br />
