Description

Technical Field

[0001] The utility model relates to the technical field of prostheses, in particular to a prosthesis for children with congenital dysplasia of the foot. Background Art

[0002] Children with congenital dysplasia of the foot are prone to inversion of the affected foot, and cannot walk like normal people.

This is a rare abnormality caused by physical defects. For children with congenital dysplasia of the foot, traditional prostheses cannot be adapted, and they can only be fitted with lower leg prostheses after amputation in adulthood, causing children to limp for many years during their growth and development, bringing great inconvenience to their lives.
