Abstract: Objective　 To build a visual digital model of the scaphoid involving intra-arterial based on Micro-CT and analyze its clinical significance.　Methods　12 cases of human forearm specimens were performed vessel perfusion. Micro-CT scan was performed and Mimics 20.0 software was used to reconstruct the blood vessels in three dimensions. The reconstructed data were collected and analyzed.　Results　(1) A clear digital model of the intra-arterial of scaphoid was reconstructed, which can freely measure the anatomical data of the scaphoid and blood vessels. (2)The branch number of nourishing vessels in the right-hand group and the left-hand group were (4.67±1.366) and (3.83±0.753), respectively. The branch number of palmar nourishing vessels were (1.67±0.516) and (1.33±0.516), respectively. The branch number of dorsal nourishing vessels were (3.00±1.095) and (2.50±0.548), respectively. 　Conclusions　The three-dimensional reconstruction of intraosseous  vessels can clearly show the source and spatial distribution of the nutrient arteries in the scaphoid bone, which providing a morphological basis for the clinical study of scaphoid fracture.
