A limb reduction defect is a congenital condition where a baby is born with missing or underdeveloped limbs, such as arms or legs. This condition can vary in severity, with some individuals having partial limbs while others may have complete absence of a limb. The exact cause is often unknown, but it can be linked to genetic factors or environmental influences during pregnancy. Diagnosis typically occurs through prenatal imaging or at birth. Treatment options may include physical therapy, prosthetics, or surgical interventions to improve function and mobility. Early intervention is crucial for helping individuals adapt and lead active lives despite the challenges posed by limb reduction defects.
