Study and development of an external aid for treating congenital talipes equinovarus (CTEV)

摘要

Clubfoot referred as congenital talipes equinovarus (CTEV) is a congenital deformity thattwists the foot, ankle, and toes. Left untreated in the early stage, it may lead to lifetime disability. With noproper treatment, the child born with clubfoot cannot walk, run or play. Clubfoot, the most commoncongenital physical disabilities worldwide, known to occur between 1 and 3 in every 1,000 live birthsworldwide with evidence of higher rates in developing nations. In a year, over 220,000 children are bornwith clubfoot in developing countries. In India, more than 50,000 children are born with Clubfoot everyyear. The most preferred type of clubfoot treatment is the use of braces or orthosis. This study deals withthe design and development of an external aid for treating children with clubfoot. The virtual model of anorthosis and the clubfoot is made using computer aided design. Then the assembly is then analyzed forpredicting the growth pattern in the foot.
