A s a result of the developments in the field of medicine, human life has been prolonged. For this reason, the ratio of elderly individuals to other individuals in the society is increasing day by day. According to the United Nations' World Population Ageing 2019 report, the world population is estimated to increase by 2 billion people and reach 9.7 billion by 2050(United Nations, 2019). According to the expectations of the World Health Organization (WHO), the number of individuals over 60 is estimated to exceed 2 billion in 2050 and the rate of deaths due to falls is estimated to increase from 28% to 42% (WHO, 2007;Chelli and Patzold, 2019). While falls of elderly people sometimes result in severe damage such as bone fracture, some falls do not cause any significant injury. The elderly person's health condition worsens as a result of the inability to get up without support after a long stay on the floor. For this reason, it is vital that the falls of elderly individuals must be detected while Article History:
The use of prosthesis plays an important role in rehabilitation in the case of
congenital absence or loss of an extremity. Apart from lower and upper extremity
prostheses, there is a wide variety of prostheses used in different parts of the body.
Unlike limb prostheses, these are permanently placed in the body by surgical
intervention and are also called implants. New studies emerge every day in the
development of innovative prostheses and implants. These innovations include material
selection, new material development, control strategies, feedback system development,
sensor and actuator development, power supply methods, and power equipment
development work. Besides, many studies aim to increase user comfort as well as
acceptance rate and the useful life of prostheses. Some researchers are working to
develop prostheses exclusively for the use of children. Innovative developments in
prostheses and implants are examined in this section. Developments are presented from
various aspects, and information is given about the research that has made significant
contributions to the field. As an example of technological development in prosthetics,
an autonomic tumor prosthesis developed for children with bone cancer is introduced at
the end of the section as a case study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
