The choice of the type of stabilization device in the osteosynthesis of dorso-lumbar spine fractures remains a subject of controversy. The present study aims to evaluate the efficiency of short segment in patients suffering post-traumatic thoracolumbar fractures. This study was conducted in the Department of Orthopedic Surgery and Traumatology of the Habib Bourguiba University Hospital, Sfax, Tunisia. All our patients had a spinal osteosynthesis via the posterior approach with a short segment pedicle screw fixation. We established a record of the pre and post-operative data, the functional results in the post-operative stage during the follow-up period and in retrospect according to the Denis Pain Scale, as well as the Oswestry score. The correction was evaluated by determining the relative gain and loss at the last period of retrospect: vertebral kyphosis, regional kyphosis, Gardner Segment Kyphotic Deformity (GSKD), and computed tomography (CT) scan in retrospect to check the quality of the arthrodesis. The average Oswestry score was 14%. Twenty-nine patients had an Oswestry score ≤40%. The relative gain obtained postoperatively was 57.3% for vertebral kyphosis, 67.2% for regional kyphosis and 71.3% for Gardner kyphosis deformity; while the loss of correction at the last follow-up was 0.6° for vertebral kyphosis, 1.5° for regional kyphosis and 0.9° for GSKD. No cases of non-union were reported. The short segment fixation makes it possible to limit operating time, the abundance of bleeding and the aggression of the soft tissues.
