Bones are living tissue. It consists of minerals like calcium, and phosphorus. They grow rapidly during one's early years, and renew themselves. The bone is considered as a linear-elastic, isotropic, and homogeneous material. Bones are the essential part of the human skeleton. It helps to support the softer parts of the body. Trauma is a major cause of death and disability in both developed and developing countries. The World Health Organization (WHO) predicts that by the year 2020, trauma will be the leading cause of years of life lost for both developed and developing nations. The project mainly concentrates on humerus bone fracture for the case of accident due to bike riding which is most prevalent among the youngsters. The project mainly deals with the injury to the shaft of humerus broken bone must be carefully fixed in position and supported until it is strong enough to bear weight. The aim of this paper was to compare the orthopaedic alloy plates [Stainless Steel, Titanium, Cobalt chrome and Zirconium] and natural fiber [Agave sisalana fiber, Musa sapientum fiber and Hibiscus sabdariffal fiber] reinforced polymer composite bone plates used in humerus fractures. So this project mainly deals with the stress analysis of bone particularly on the humerus bone during the fixation of plate. The deflection of the bone is calculated manually and the value is compared with the ANSYS solution and the aid of rehabilitation of patients having acute pain on upper limp and vertebrae is affected by calculating the load on the spine due to plate fixation. Also this paper focuses a new method of using data obtained from CT images combined with digital CAD and rapid prototyping model for surgical planning and this new application enables the surgeon to choose the proper configuration and location of internal fixation of plate on humerus bone during orthopaedic surgery.
