Materials and methods: 53 clubfeet in 34 infants with a mean age of 2.43 ± 1.97 months were examined clinically using Pirani score. Sonographic examination was done in medial, lateral and posterior projection in affected feet. The sonographic parameters measured were: Medial Malleolar Navicular distance (MMN), Calcaneo-cuboid angle (CC angle) and Tibio-calcaneal distance (TC). Treatment was done with Ponseti method of serial manipulation and casting. Weekly assessment was done clinically by Pirani scoring and various Ultrasonographic parameters. Pirani score were correlated with Ultrasonographic parameters.
