Abstract

Study design: Prospective clinical.
Objective: Evaluate efficacy of monosegmental transpedicular fixation for treatment of
some thoracolumbar burst fractures.
Summary: Short segment posterior fixation become a popular technique to treat
thoracolumbar burst fracture. It is saving more motion segments throughout reducing
fusion segment numbers, Previous investigations which used monosegmental pedicle
instrumentation with placement pedicle screws into fractured vertebral body for
treating thoracolumbar fracture yielded good clinical results.
Method: 20 thoracolumbar burst fractures cases treated with monosegmental
transpedicular fixation. All patients were followed-up radiologically and clinically. The
preoperative, initial postoperative and the latest follow-up radiographs were evaluated
for sagittal index, percentage of anterior body height compression and load sharing
score. Clinically the latest follow-up functional outcomes were evaluated using
Oswestery Disability Index and Low Back Outcome Score.
Results: 20 patients were followed-up successfully with the mean follow up period was
17 months. Sagittal index value of, anterior body height compression fractured
vertebra% are 19.1+/-5.4 degrees and 37.03+/-10.87, respectively, improved
(statistically significant) to 10.4+/- 4.16 degrees, and 19.3+/-9.6.
Conclusion: In conclusion, this study demonstrated that MSPI is effective and reliable
operative technique for selected thoracolumbar burst fractures (type A3.1/A3.2).
