Constriction Band Syndrome (CBS) is a rare condition that occurs during fetal development, where a band of tissue wraps around a limb or digit, restricting its growth. This can lead to deformities, such as missing fingers or toes, and in severe cases, can affect the entire limb. The exact cause of CBS is not well understood, but it is believed to be related to factors like amniotic band syndrome. The severity of CBS varies widely among individuals. Some may experience only minor cosmetic issues, while others may face significant functional challenges. Treatment options often include surgery to release the constricting band and improve limb function. Early intervention is crucial for optimal outcomes.
