What to do if i am double jointed in my fingers, is it considered a birth defect?

Not specificly: In simplistic terms a bd might be considered any abnormality found in a baby at birth. A better, more specific idea is a failure of a tissue or structure to form properly in fetal development.(cleft palate). A "disruption" can create a bd -loss of fingers to amnionic bands. Chromosome defects lead to several bd's like heart defects.Being double jointed might be considered a variation, not a defect.
