Abstract
Contrast medium was used to fill the sesamoidian canal through the coffin joint as well as the arterial blood supply to the navicular bone in 90 navicular bone‐coffin bone specimens. The radiological examinations of the arterial blood supply was done with a new technique (fine‐focus) which allows enlargements of up to 200 fold. The material was divided into the following 4 groups on radiological and pathomorphological grounds: 1. normal navicular bones (46), 2. navicular bones with changed sesamoidian canals (33), 3. navicular bones with central collapse (9) and 4. navicular bones after a penetrating injury (2). The characteristic radiological picture of the arterial blood vessel distribution is described for each group. By comparing and differentiating the radiological arterial blood supply of the different groups, it can be concluded that the blood supply to the navicular bone changes with radiological and patho‐morphological changes.
