Formation of the skeletal elements of the foot involves different stages of development. Failure in segmentation of the cartilaginous plate is supposed to be the underlying mechanism leading to tarsal coalition. Variants or disorders in ossification might result in harmless osseous anomalies or symptomatic disease. When the ossification is almost completed, several secondary ossification centers start to ossify. They are usually incidental findings. In symptomatic patients they have to be differentiated from fractures or can be the source of complaints by themselves.
足部骨骼元素的形成涉及不同的发育阶段。软骨板分割失败被认为是导致跗骨联合的潜在机制。骨化过程中的变异或紊乱可能导致无害的骨异常或症状性疾病。当骨化几乎完成时，几个 secondary ossification centers 开始骨化。它们通常是偶然发现。在有症状的患者中，它们必须与骨折相鉴别，或者本身就是主诉的来源。 （注：原文中“secondary ossification centers”直译为“次级骨化中心”，这里为了符合中文表达习惯，也可意译为“继发骨化中心” ）
