Project description

Clubfoot is a congenital deformity of the foot also known caused by the abnormal development of a baby’s bones, ligaments and muscles whilst in the womb. The congenital clubfoot is easily remedied by applying 5-6 casts and handling provided for in the Ponseti method to children between the ages of seven days to one year.
The proposed device is a orthosis useful to keep the foot in the correct position. The muscles and ligaments of the infants are flexible, so applying a suitable force on the foot and ankle parts, for a sufficient time, it is possible to correct the malformation. The leg is shaped by imposing a 90 degrees angle between the thigh and the calf, in accordance with the specifications prescribed by the Ponseti method. The device consists of an upper and lower part, which are joined to the baby's leg through 4 Velcro bands, which are located at the bottom. Each part has a thickness of 2.5 mm and the material used is ABS. The orthosis is carved to allow the leg's perspiration. The device is applied to the infant by placing the leg in the lower part, matching the lower upper part, and sequentially closing the 4 Velcro bands to secure the orthosis. According to the Ponseti method, orthosis will be removed after 7 days by opening the Velcro bands and pulling out the leg.
