Short segment versus long segment pedicle screws fixation in management of thoracolumbar burst fractures

Abstract

Background: Selection of stabilization procedures for treating thoracolumbar burst fractures remains controversial. Both long-segment and short-segment pedicle screw fixation have been used widely with no consensus on the better method. Aim of study: To compare the outcome of long segment and short segment posterior fixation as amanagement of thoracolumbar burst fractures. Patients and Methods: 60 patients fulfilling the inclusion criteria who underwent posterior pedicle screw fixation for burst fracture of thoracolumbar spine in Neurosurgery Department of Al-Azhar University Hospitals and El-Ahrar General Hospital, Zagazig between August 2019 and Febrauray 2022. Patients were randomized into one of two groups. Short segment group (30 patients) was treated by short segment fixation, i.e., 1 level above and 1 level below the fractured vertebra. Long segment group (30 patients) was treated by long segment pedicle screw fixation, i.e., fixation of 2 levels above and below the fractured vertebra. Assessment of kyphosis correction by using the Cobb method and restoration of the anterior vertebral body height was performed radiologically postoperatively and at 3 and 6 months follow up. Results: Demographic data of both groups were quite comparable. thoracolumbar burst fracture
