C sign incidence, C sign figuration, distance of the medial facet of talocalcaneal joint, and the figuration of sustentaculum tali were studied. The relationship between C sign and talocalcaneal coalition was analysed.Results The incidence of C sign was 54.6%(422/773). The female incidence was 61.1%(127/208) ,which was more than that of male(52.2%,295/565)(P
