CT scan of a 75-year-old patient in the pre-operative (a), immediate post-operative (b), and 6 months post-operative (c) stages, who underwent cemented percutaneous long posterior instrumentation for a T11–T12 fracture. Despite the absence of an anterior procedure, there is a progressive correction of the anterior diastasis at 6 months: preoperative lordotic angulation was 9.5°, immediate postoperative angulation was 15.5° and angulation at the late postoperative stage was 6°.
