Abstract: The calcaneonavicular coalition is a malformed condition between calcaneus and navicular. There are three forms of coalition: bone, cartilage and fibrous.At present, the mainstream view is that the calcaneonavicular coalition is the result of the differentiation failure of mesenchymal cells during the embryo. The 45° oblique radiographic view of hind foot is conducive to the diagnosis of calcaneonavicular coalition.Computed tomography（CT） scan and magnetic resonance imaging（MRI） are of great value in the identification of coalition.Conservative treatment, such as non-steroidal anti-inflammatory drugs（NSAIDs） and short leg cast, can effectively relieve the symptoms of calcaneonavicular coalition, and patients who failed in conservative treatment can be treated by traditional open operation and minimally invasive surgery. By consulting the relevant literature, we reviewed the etiology, diagnosis and treatment of the calcaneonavicular coalition, so as to enhance the clinicians' understanding and improve the diagnostic rate.
