“…This kind of registration process can reduce error origin from surgeon-dependent registration which requires a learning curve in selecting and matching the anatomical landmarks for optimal registration. [8] But remaining problems are how to attach the DRF firmly to the patient and maintain its stable position during the operation without inhibiting the surgeon's motion. Because the accuracy of the navigation system highly depends on the integrity of DRF which maintains the synchronization between the virtual navigated positions and the actual anatomical positions, consequently stable fixation of the reference frame is a critical step in navigated surgery.…”

(2015) Novel method for setting up 3D navigation system with skin-fixed dynamic reference frame in anterior cervical surgery, Computer Aided Surgery, 20:1, 24-28, DOI: 10.3109/10929088.2015 Purpose: To introduce easy and useful methods using 3D navigation system with skin-fixed dynamic reference frame (DRF) in anterior cervical surgery and to validate its accuracy. Methods: From September 2012 to May 2013, 31 patients underwent anterior cervical surgery and a total of 48 caspar distraction pins were inserted into each cervical vertebra. Every operation was performed using O-arm Õ navigation system with skin-fixed DRF. To validate the accuracy of these methods, a custom-made metal sleeve was used. In surgical field, through the metal sleeve, the tip of a navigation probe promptly contacts to the tip of caspar pin. We measured the vertical and horizontal distances and the angular deviation in sagittal plane between the caspar pin and the navigation probe on the virtual images and evaluated accuracy of navigation system with skin fixed DRF. Results: Total 31 (males 20, females 11) patients and 48 caspar pins were included in this study. The mean horizontal distance between the caspar pin and the navigation probe displayed in navigation monitor was 0.49 ± 0.71 mm. The mean vertical distance between the caspar pin and the navigation probe displayed in navigation monitor was 0.88 ± 0.93 mm. And the mean angular deviation in sagittal plane between the caspar pin and the navigation probe displayed in navigation monitor was 0.59 ± 0.55 . Conclusions: 3D navigation system with skin-fixed DRF in anterior cervical surgery is a simple and reliable method and it can be a helpful supplement to a spine surgeon's judgement. ARTICLE HISTORY

“…Different registration algorithms have been developed; they differ in terms of the type of image data used by the navigation system (preoperatively acquired computed tomography [CT] images, intraoperatively acquired fluoroscopy images), and the way virtual and physical reality is matched. Generally, registration procedures based on active intraoperative registration and automated registration procedures can be differentiated [23][24][25][26]. For the automated registration procedure, either 2D or 3D fluoroscopic images are acquired intraoperatively.…”

Since the first use of instrument-tracking techniques in the early 1990s, image-guided technologies became a leading topic in all branches of spine surgery. Today, navigation is a widely available tool in spine surgery and has become a part of clinical routine in many centers for a large variety of indications. Spinal navigation may not only contribute to more precision during surgery, but it may also reduce radiation exposure and fluoroscopy time, with advantages not only for the patient but also for the operating room personnel. Different registration algorithms have been developed differing in terms of the type of image data used by the navigation system (preoperatively acquired computed tomography [CT] images, intraoperatively acquired fluoroscopy images) and the way virtual and physical reality is matched. There is a tendency toward a higher accuracy for 3D fluoroscopy-based registration algorithms. The O-arm(®) represents a new flat-panel technology with the source and detector moving in a 360° arc around the patient. In combination with the Stealth(®) station system, navigation may start immediately after automated registration with already referenced instruments. After instrumentation, an additional scan may confirm intraoperatively the correct positioning of the instrumentation. The first experiences with the system are described in this paper.

Image-guided surgery (IGS) has been evolving since the early 1990s and is now used on a daily basis in the operating theater for spine surgery at many institutions. In the last 5 years, spinal IGS has greatly benefitted from important enhancements including portable intraoperative CT (iCT) coupled with high-speed computerized stereotactic navigation systems and optical-based camera tracking technology. Historical PerspectiveCranial stereotaxy was developed by Kirschner in 1933, refined by Lars Leksell in 1949, and translated by Robert Brown and Theodore Roberts in 1979 into the Brown-Roberts-Wells stereotactic system. 21,24,28,35 Cranial stereotaxy employed frames that were attached to the skull for numerous surgical intracranial procedures including intraaxial and skull base tumor resection, vascular malformation resection, resection for epilepsy, and ablation and stimulation procedures for Parkinson's disease and other functional disorders. 3,4,11,12 Today, frame-based technology is used only for some cranial procedures in which the highest possible accuracy is needed. Frame-based cranial stereotaxy led to the development of frameless cranial stereotaxy. Frameless cranial stereotaxy, in turn, led to the development of spinal frameless stereotaxy, now referred to simply as IGS for both cranial and spinal procedures. 18,40 Frame-Based and Frameless Spinal Stereotaxy ProceduresFor a period of time, frame-based spinal technology was used for the limited applications of stereotactic radiosurgery to treat spinal neoplasms. 25,32 Since the advent of frameless stereotactic radiosurgery procedures, framebased procedures are rarely, if ever, used. The "frameless stereotaxy" that we currently use is now referred to as spinal IGS. This technology utilizes 3D imaging reconstruction produced by iCT scanning, digital optical imaging systems, and high-speed computer processing. Instead of the attached frame previously used, this technology uses only a tracking device attached to the spine to create the 3D computerized tracking environment.As clinical applications for frameless spinal stereotaxy evolved, they were reported in the literature. In 1991, Nelson and Duwelius reported their novel application of iCT to facilitate sacral fixation.26 In 1993, Brodwater et al. described utilization of the microscope to evaluate lumbar spinal anatomy, creating an interest in the use of IGS for hardware placement. 6 In 1995, Kalfas and colleagues published their experience with IGS-based placement of pedicle screws in the lumbar spine, in what appears to be the initial application of spinal IGS for hardware placement. 17 In 1996, Foley and Smith published a paper presenting a broader clinical application of IGS technology to spine surgery procedures.9 Following these initial publications, IGS for spinal procedures in various regions of the spinal column were reported by surgeons from across the country. 2,5,15,20,38
