Objective　To study anatomical characteristics of longitudinally-severed fingers via digitized virtual technology.　Methods　Multiple dissections of hand were performed by software of Mimics, and the finger was cut into a palm-half and a dorsum-half from tip to metacarpophalangieal striation along the midline of finger via the tools of Mimics. Many forms of digitized virtual longitudinally-severed fingers were obtained. All parts were observed, measured and analyzed.　Results　Anatomic structures were exactly showed on the virtual hand, through the multiform solitude or combined ways. Digital bone, extensor and flexor tendons, innate arteries, and nerves can be cut longitudinally into multiple parts, involving oblique, transverse or longitudinal rupture or loss on some segments. The morphologic features of digitized virtual injured hand looked like that of actual traumatic hands.　Conclusions　The visible hand model can provide 3D morphological data for clinical practice and research of longitudinally-severed fingers, as well provide digitized model for virtual reality.
