Astragalectomy, sometimes called a talectomy, is a surgical operation for removal of the talus bone (astragalus) for stabilization of the ankle. Historically, an astragalectomy was used in cases of severe ankle trauma and congenial talipes equinovarus (clubfoot). It is no longer a common operation, but is still used in cases of a deformed calcaneus, foot paralysis following poliomyelitis, and rigid clubfoot deformities that are secondary to spina bifida or arthrogryposis (AMC). The surgery is also performed in severe cases of pulverized or infected open fractures.
