The internal architecture of the talus has not previously been well described even though the morphological anatomy and the blood supply have been studied extensively. This study describes the internal architecture of the talus regarding its trabecular orientation, using high-resolution x-ray images of 13 dry tali and thick sections in the coronal, sagittal, and axial planes. The trabecular arrays and their relationship to talar fractures are described. The trabecular content of the neck of the talus is less than that of the head or the body. The direction of the trabecula in the neck is different from the orientation of the talar body trabeculae.
