A Novel Intravertebral Fixation Technique of Lumbar Osteoporotic Vertebral Bipedicular Dissociation Fractures.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveA significant portion of traumatic spinal fractures involves the thoracolumbar spine. Fracture stabilization using pedicle screws initially demanded fixation of two levels above and below the fractured vertebra to achieve a stable construct. Over the years, a short-segment pedicle screw fixation was found to be adequate. Balloon kyphoplasty (BKP) is commonly used as a minimally invasive treatment for vertebral compression fractures. At times, lumbar burst fractures can extend to the posterior elements. These recently acknowledged subtypes of fracture do not cause posterior column instability other than coronal bipedicular dissociation. BKP alone is inadequate in these cases; a combination of BKP addressing anterior column reduction and support with a middle column stabilization by transpedicular fixation has the potential to treat all fracture elements without losing motion segments through a minimally invasive technique. This study aims to describe this novel concept and technique.
methodsFive patients were treated with the intravertebral fixation (IVF) technique for coronal bipedicular dissociation fractures. We describe the surgical technique and review the pertinent literature.
resultsThe IVF technique is clinically safe in stabilizing the specified fractures, with good clinical and functional outcomes.
conclusionIVF is a promising surgical technique and an exciting treatment concept for unique fracture types involving bipedicular coronal dissociation with or without burst fracture. Further studies are required to assess long-term results and possible complications. STUDY
