Stereo information of skeletal data based on CT sequence medical images

Abstract

In order to study the three-dimensional information of skeletal data from CT (Computed Tomography) serial medical images, 100 cases of distal posterior tibial fracture were selected, X-ray films of ankle joint were taken, and plain CT scan and three-dimensional reconstruction were performed to evaluate the fracture situation. According to the CT images, the cases were divided into posterior Pilon fracture and posterior ankle fracture. The results showed that Pilon fracture accounted for 62% and there were 39 males and 23 females, 32 left and 30 right. There were 38 cases of posterior ankle fracture, 28 males and 10 females, 20 left and 18 right. There were many types and forms of posterior Pilon fracture and posterior ankle fracture. It showed that the main cause of distal posterior tibial fracture is violence. Axial violence of tibia or torsional violence of lower limbs often causes Pilon fracture. Avulsion fracture caused by torsional violence mostly belongs to posterior ankle fracture. To sum up, stereoscopic information of bone data was obtained through CT images of tibia.
