Current Navigation Modalities in Spine Surgery With a Focus on the Use of the O-arm in Deformity Surgery
نویسندگان
چکیده
2 Division of Orthopaedic Surgery, The Children’s Hospital of Philadelphia, Philadelphia, PA Image guidance in spine surgery has evolved from static modalities such as the plain radiograph to navigation systems such as the O-arm. Commonly used modalities include CT scan based navigation systems, 3D fluoroscopy, and most recently the O-arm. Each of these navigation systems improved on the capabilities of its predecessor with the O-arm being the most recent system. The O-arm obtains multiplanar images of the spine intra-operatively. These images can be used for navigation or for rapidly assessing the safety of implants within the spine. We currently use the O-arm for image guided instrumentation during deformity surgery.

There has been a large series in the literature reporting on results of osteotomy for the correction of kyphotic deformity secondary to post-traumatic thoracolumbar fracture. However, there are few reports on using intraoperative, full rotation, three dimensional image (O-arm)-based navigation, transpedicular wedge osteotomy for the correction of kyphotic deformity in old thoracolumbar fracture...
