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.
