Adjacent Single-level Combined Fixation Using Kyphoplasty and Percutaneous Pedicle Screws in Type A3 Unstable Vertebral Fractures in Elderly Patients.

Abstract We present a series of cases of type A3.1.2 unstable fractures of the thoracolumbar hinge treated percutaneously with third-generation kyphoplasty and only one next level percutaneous screws. Four women aged 75 to 85 years with thoracolumbar vertebral fractures, classified as type A.3.1.2, were treated with Precept® monosegmental percutaneous fixation and the third-generation SpineJack® augmentation system. The traditional treatment of type A3 unstable vertebral wedging fractures is performed with transpedicular fixation of two or more levels adjacent to the fracture causing great rigidity. Recently, the concept of bridge fixation combining one segment intrapedicular fixation with kyphoplasty has emerged as a more stable and less invasive system that allows greater mobility in this type of fractures. The combination of third-generation kyphoplasty and monosegmental bridge fixation may improve results to other fixation systems in type A3 vertebral fractures
