ABSTRACT
This chapter provides a detailed description of pathoanatomy and principles of correction. The subtalar joint is a complex joint having a great role in the pathology of clubfoot. In severe clubfoot deformities, there is disorganization of the arched function of the foot and there is a definite functional handicap, even for normal functions with diminished earning capacity involving physical labor, in addition to the appearance along with the consequent psychological handicap. The abnormality of the deltoid and spring ligaments and the posterior capsule of the ankle joint all play a complementary role in causing and maintaining the deformity. The calcaneo-cuboid joint is an important joint in clubfoot deformity and gets deformed increasingly with increasing age. Idiopathic congenital clubfoot is one of the most common conditions seen in orthopedics, but it remains an unsolved problem. Equinus is the most important component of the clubfoot deformity.
