Bilateral congenital trigger thumb: role of heredity

Bilateral congenital trigger thumb is a relatively uncommon condition, with few well documented cases in literature. Lack of awareness and mode of presentation creates diagnostic confusion to a majority of physicians who are not familiar with this condition. There is also controversy surrounding its aetiology, natural course, ideal treatment and the age for intervention. We report the case of bilateral congenital trigger thumb in a mother and child, review the literature and discuss the possible hereditary influence which is still less known and reported.
