Limb reduction defects are congenital conditions where a baby is born with missing or underdeveloped limbs, such as arms or legs. These defects can vary in severity, with some children having a complete absence of a limb, while others may have a limb that is shorter or malformed. The exact cause of these defects is often unknown, but they can be influenced by genetic factors or environmental exposures during pregnancy. Treatment for limb reduction defects often involves a combination of surgery, physical therapy, and the use of prosthetics. Early intervention can help children develop mobility and independence. Support from families and organizations, such as March of Dimes, can also play a crucial role in helping affected children thrive.
