Syndactyly is a congenital condition where two or more fingers or toes are fused together. This fusion can involve soft tissue, bones, or both, and can vary in severity. It is often identified at birth and can affect one or both hands or feet. The exact cause of syndactyly is not always known, but it can occur as an isolated condition or as part of a genetic syndrome. Treatment typically involves surgery to separate the fused digits, improving function and appearance. Early intervention can lead to better outcomes for those affected by this condition.
