 Fibular oplasia, tibial campimilia, and oligosindactyly-FATCO syndrome is a rare genetic condition characterized by unilateral or bilateral fibular oplasia, tibial campimilia, and lower limb oligosindactyly involving the lateral rays. It is often accompanied by other congenital anomalies such as cleft palate, cardiac defects, and renal abnormalities. The condition is typically diagnosed shortly after birth, but can also present during childhood or adulthood. Symptoms include limb deformities, joint contractures, and muscle weakness. Treatment for FATCO syndrome involves surgical intervention to correct the deformities, physical therapy to improve mobility, and orthotic devices to support the affected limbs.
