The effectiveness of short-segment posterior instrumentation of thoracolumbar burst fractures
Abstract
Objectives: We evaluated the results of short-segment posterior instrumentation of thoracolumbar burst fractures and investigated correlations between radiographic and functional results as well as factors that affected correction losses.
Methods: We reviewed 48 patients (30 males, 18 females; mean age 40±14 years; range 18 to 67 years) who underwent short-segment posterior instrumentation with pedicle screws and fusion. The most common involvement was at L1 in 18 patients (37.5%), followed by T12 in 11 patients (22.9%). According to the Frankel grading system, six patients had complete, 14 patients had incomplete neurologic deficits. The Cobb angles were measured, and canal remodeling was assessed by computed tomography. Modified functional results were derived using the Denis pain and work scales. The mean follow-up was 21.7±9.1 months (range 12 to 48 months).
Results: The mean correction in the Cobb angle was 18.2±8.6° (p
