Congenital musculoskeletal malformations in neonates.

A total of 13321 consecutive live births were studied for the incidence of congenital musculoskeletal malformations (CMSM) in neonates in relation to mother's age, parity, social class, sex and birth weight of the child. In all, 64 CMSM were observed in 54 neonates (4.054 per thousand live births). Congenital talipes equinovarus was the commonest CMSM while polydactyly and arthrogryposis were the next common CMSM in order of frequency. CMSM were more commonly seen in lower socio-economic class and in low birth weight babies.
