Overview
Congenital deformities of limbs is a broad group of conditions where a baby is born with one or more arms or legs that did not develop normally during pregnancy. These differences can range from mild, such as a finger or toe being slightly shorter or curved, to more significant, such as a missing hand, foot, or entire limb. Some babies may have extra fingers or toes (polydactyly), fused fingers or toes (syndactyly), shortened limbs, or limbs that are bent or twisted in unusual ways. These conditions are present at birth and are sometimes detected on prenatal ultrasound. The causes of congenital limb deformities are varied. Some are linked to specific genetic changes, while others may result from disruptions during fetal development, such as amniotic band syndrome, exposure to certain medications, or unknown environmental factors. In many cases, no clear cause is found. Some limb deformities occur as isolated findings, while others are part of a broader genetic syndrome that affects multiple body systems. Treatment depends on the type and severity of the limb difference. Options may include physical therapy, occupational therapy, prosthetic devices, orthotic braces, and reconstructive surgery. Many children with congenital limb deformities adapt remarkably well and lead full, active lives. A team of specialists typically works together to create a personalized care plan that supports the child's growth, function, and quality of life.
