A Novel Intravertebral Fixation Technique of Lumbar Osteoporotic Vertebral Bipedicular Dissociation Fractures.
Case Report
A 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./r/nFive patients were treated with the intravertebral fixation (IVF) technique for coronal bipedicular dissociation fractures. We describe the surgical technique and review the pertinent literature./r/nThe IVF technique is clinically safe in stabilizing the specified fractures, with good clinical and functional outcomes./r/nIVF 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./r/nCase series for a new surgical technique.
