Abstract Objective To investigate the application of CT and three-dimensional reconstruction technology in the measurement of pedicle outer width (POW) of osteoporotic vertebral compression fractures in patients and middleaged and young people with thoracolumbar fractures(T₁₁~L₅).Methods Data of all patients with thoracolumbar fracture treated in our hospital from October 2016 to June 2018 were collected for retrospective analysis.Among them，105 patients with OVCF were group A，with an average age of (73.26±6.28)years old.The 72 cases of traumatic thoracolumbar fracture treated at the same time were group B，with an average of (38.90±8.58)years old.The POW values of both sides of vertebral pedicle corresponding to T₁₁~L₅ and the differences between different gendersbetween the two groupswere compared.And we calculated the patientpercentages of POW less than 5mm and 7mm.Results There was no statistical difference in POW of the left and right sides of the spine between the two groups (P＞0.01).The POW corresponding of T₁₁~L₃ in groups A was smaller than that in group B (P＜0.01)，and no difference in L₄ and L₅.There were 118 patients in group A withPOWless than 5 mm，accounting for 8.03% of the total number of the group，mainly distributed in the spine of T₁₁~L₃，and 15 patients in group B whose POW less than5mm，accounting for 1.49%.The proportion of patients with POW less than7mm in group A was 46.87%.distributedin T₁₁~L₄，and the proportion of patients with POW less than 7mm in group B was 13.10%，distributed in T₁₁~L₃.Conclusion Three-dimensional CT reconstruction examination before surgery can effectively measure the width of pedicle，evaluate the feasibility of surgical treatment，and help reduce the incidence of surgical complications.
