Medial talo-calcaneal coalition is an uncommon developmental anomaly consisting of a bony projection arising from the postero-medial aspect of the sustentaculum tali, which may articulate with another bony projection from the medial aspect of the talus. Fibrous, cartilaginous or bony ankylosis may occur. It usually presents in adolescents, and causes pain following exercise. It may cause a lump, and can predispose to flat foot and early osteoarthrosis. This condition is easily overlooked on routine views of the ankle, and may require oblique views and tomography for its detection and clarification.
距下关节内侧联合是一种罕见的发育异常，表现为从跟骨载距突后内侧长出的骨性突起，该突起可能与距骨内侧的另一个骨性突起相连。可出现纤维性、软骨性或骨性融合。通常在青少年期出现，运动后引起疼痛。可能导致肿块，并易引发扁平足和早期骨关节炎。在踝关节常规X线片上这种情况很容易被忽视，可能需要拍摄斜位片和进行体层摄影来发现和明确诊断。
