BACKGROUND CONTEXT: Quick-segment posterior spinal instrumentation for thoracolumbar burst fracture offers superior correction of kyphosis by an oblique discount approach, but it surely has a excessive failure price.
PURPOSE: The aim of the research we report right here was to match outcomes for short-term short-segment pedicle screw fixation with vertebroplasty and for such fixation with out vertebroplasty.
STUDY DESIGN: This can be a potential multicenter comparative research.
PATIENT SAMPLE: We studied 62 consecutive sufferers with thoracolumbar burst fracture who underwent short-segment posterior instrumentation utilizing ligamentotaxis with Schanz screws with or with out vertebroplasty.
OUTCOME MEASURES: Radiological parameters (Cobb angle on standing lateral radiographs) had been used.
METHODS: Implants had been eliminated roughly 1 12 months after surgical procedure. Neurologic perform, kyphotic deformity, canal compromise, and fracture severity had been evaluated prospectively.
RESULTS: After surgical procedure, all sufferers with neurologic deficit had enchancment equal to at the very least one grade on the American Spinal Harm Affiliation impairment scale and had fracture union. Kyphotic deformity was diminished considerably, and discount of the vertebrae was maintained with and with out vertebroplasty, no matter load-sharing classification. Though no affected person required further anterior reconstruction, kyphotic change was noticed at disc stage primarily after implant elimination with or with out vertebroplasty.
CONCLUSIONS: Momentary short-segment fixation yielded passable leads to the discount and upkeep of fractured vertebrae with or with out vertebroplasty. Kyphosis recurrence could also be inevitable as a result of adjoining discs might be injured through the authentic trauma.
