Background: The management of dorsolumbar fractures has been the subject of much controversy. There are different criteria for the choice of management based on the severity of the kyphotic deformity, canal compromise, vertebral height loss, and neurologic status. Objective:To evaluate the results of surgical management of high energy dorsolumbar fractures in the Trauma Unit at Assiut, and at Al-Azhar University Hospitals. Patients and Methods: From October 2017 to October 2019, 40 patients with thoracolumbar spine (TLS) fractures, all of them were treated by posterior instrumentation with pedicle screws and rod system. 23 petients (57.5%) underwent long-segment fixation and 17 patients (42.5%) underwent short-segment fixation. They were operated upon at the Trauma Unit of Assiut University Hospital and Al-Azhar University Hospital. Results:The clinical outcome according to modified Macnab criteria; in long segment group it was excellent in 8 patients (34.7%), good in 11 patients (47.8%), fair in 3 patients (13% ) and poor in 1 patient (4.3%), while in short segment group; it was excellent in 3 (17.6%), good in 10 (58.8%), fair in 3 (17.6%)andpoor in 1 (5.9%). The kyphosis correction (%), in long segment group was ≥70 in 16 patients (70%), <70 in 7 patients (30%), while in short segment group, it was ≥70 in 10 patients (59%) and <70 in 7 patients (41%). Conclusion: Short segment fixation using pedicle screw at the level of fracture, inhigh energy thoracolumbar fractures; provides comparable correction to long segment fixation and the amount of correction loss can be minimized by proper selection of cases suitable for short segment fixation.
