Internal architecture of the talus: Implication for talar fracture

The internal architecture of the talus has not previously been well describ ed even though the morphological anatomy and the blood supply have been stu died extensively. This study describes the internal architecture of the tal us regarding its trabecular orientation, using high-resolution x-ray images of 13 dry tall and thick sections in the coronal, sagittal, and axial plan es. The trabecular arrays and their relationship to talar fractures are des cribed. The trabecular content of the neck of the talus is less than that o f the head or the body. The direction of the trabecula in the neck is diffe rent from the orientation of the talar body trabeculae.
