Abstract
Introduction
Although open procedures are the gold standard, the alternative approach of minimal invasive reduction using percutaneous screws for thoracic and lumbar spine fractures is under discussion. Aim of this study was to investigate the results of reduction and the accuracy of screw placement in minimally invasive percutaneous posterior instrumentation for these fractures.
Materials and methods
One hundred and twenty-seven patients with thoraco-lumbar and lumbar burst fractures and minimal invasive dorsal instrumentation were analyzed retrospectively in terms of the accuracy of pedicle screw placement and results of fracture reduction.
Results
In total, 542 screws were placed. Thirty-four (6.3%) screws of 22 patients (17.3%) were misplaced, but misplacement was minimal, replacement of any screw position due to instability was not necessary, and no new neurological deficit occurred. In thoraco-lumbar fractures (82/64.5%), reduction succeeded from 2.5 ± 6° kyphosis to 5.6 ± 5.7° lordosis (p < 0.001) and in lumbar spine fractures from 6.9° ± 10.3° lordosis to 14.5° ± 8.8° lordosis (p < 0.001).
Conclusion
Minimal invasive percutaneous dorsal instrumentation of burst fractures of the thoraco-lumbar and lumbar spine provides adequate reduction and reliable regular screw placement.
Level of evidence
Level IV (retrospective series).
