Spinal trauma chapter brings together information on state-of-the-art clinical imaging, including multidetector CT and high-field MRI techniques and the pathophysiology, neurologic evaluation, medical management, surgical treatment, and postoperative assessment of spine trauma and spinal cord injury. Techniques for spinal procedures include the most common types of instrumented procedures such as anterior cervical discectomy and fusion, cervical arthroplasty, occiput C1, and C2 instrumentation, lumbar microdiscectomy, lumbar arthroplasty, posterior, transforaminal and anterior lumbar interbody fusion, and indications and techniques of revision spine surgery.
