Objective: To evaluate the prevalence of congenital malformations in the upper limb and their associations with other birth defects and syndromes in Brazil and Latin America.

Methods: The analyzed material provided by Latin American Collaborative Study of Congenital Malformations (ECLAMC) was collected from 1982 to 2006. Variables were used in two databases: the first has monthly information of all live births and deaths and the second contains information of all malformed infants. The prevalence defined was: total, isolated, associated with congenital syndromes and the polymalformed.

Results: The sample of 4,564,560 births that were analyzed, is relative to 62,260 deaths and 4,502,300 alive during the period from 1982 to 2006. With reference to congenital malformation of the upper limb and associated malformations, we found a total of 11,645 (1:392) cases. 7,729 (1:588) were isolated. When associated with other malformations and polymalformed there were 3916 (1: 1162), according to the ICD 10.

Conclusion: The epidemiology of congenital anomalies of the upper limb are important for planning, monitoring, prevention and research.
