Foot Ankle Surg. 2012 Sep;18(3):e34-6. doi: 10.1016/j.fas.2012.01.002. Epub 2012 Mar 7.


Talonavicular coalition is a rare autosomal recessive congenital anomaly that is usually asymptomatic and detected incidentally on radiographs. It is associated with symphalangism, clinodactyly, a great toe that is shorter than the second toe, clubfoot, calcaneonavicular coalition, talocalcaneal coalition and a ball-and-socket ankle joint. The authors present a review of the literature and case report of a patient with complete osseous talonavicular coalition, talocalcaneal coalition and lateral ankle instability which was successfully treated with subtalar fusion and lateral ligament reconstruction.
