“…Based on intraoperative assisting method, computer-assisted surgery could be subclassified into three types including volumetric image-based navigation, fluoroscopic navigation and imageless navigation [57]. The first one uses preoperative images such as CT and MRI, while the second one utilizes intraoperative twodimensional or three-dimensional fluoroscopic images.…”

“…The first one uses preoperative images such as CT and MRI, while the second one utilizes intraoperative twodimensional or three-dimensional fluoroscopic images. Imageless navigation makes use only of intraoperative anatomical information and is mainly employed to assist total hip/knee arthroplasty [57]. In our review, we found three major navigation systems that had been used to assist pedicle screw insertion including computer tomographybased navigation system (CT Nav), two-dimension fluoroscopy-based navigation system (2D FluoroNav) and three-dimension fluoroscopy-based navigation system (3D FluoroNav).…”

“…With the development of the 3-D C-arm, 3D FluoroNav gradually gained popularity in spinal surgeries. Though its image quality is lower than that of CT, 3D FluoroNav provides real-time three-dimensional images, which serves as both C-arm and CT-based navigation, and does not need registration [57,58].…”

“…On comparing the navigated and conventional methods, most studies indicated that CTNav increased the time for spinal surgeries [15,23,26,37,41,44]. This might be attributed to extra protocols such as preoperative images, modeling and simulation, and registration [12,40,57,58]. One of the drawbacks of the CTNav is the considerable learning curve in the registration process.…”

Studies revealed that navigation systems that provided intraoperative assistance might improve pedicle screw insertion accuracy, and also implied that different systems provided different pedicle screw insertion accuracy. A systematic review and meta-analysis was conducted to focus on the pedicle screw insertion accuracy with or without the assistance of image-guided system, and the variance among the different navigation systems. Comparative studies were searched on pedicle screw insertion accuracy between conventional and navigated method, and among different navigation systems. A total of 43 papers, including 28 clinical, 14 cadaveric and 1 model studies, were included in the current study. For clinical articles, there were 3 randomized clinical trials, 4 prospective comparative studies and 21 retrospective comparative studies. The incidence of pedicle violation among computer tomography-based navigation method group was statistically significantly less than that observed among the conventional group (OR 95% CI, in vivo: 0.32-0.60; in vitro: 0.24-0.75 P \ 0.01). Two-dimensional fluoroscopybased navigation system (OR 95% CI, in vivo: 0.27-0.48; in vitro: 0.43-0.88 P \ 0.01) and three-dimension fluoroscopy-based navigation system (OR 95% CI, in vivo: 0.09-0.38; in vitro: 0.09-0.36 P \ 0.01) also obtained significant reduced screw deviation rate over traditional methods. Between navigated approaches, statistically insignificant individual and pooled RR values were observed for all in vivo subgroups. Pooled estimate of in vitro studies show that computer tomography-based and three-dimension fluoroscopy-based navigation system provided more accurate pedicle screw insertion over two-dimension fluoroscopy-based navigation system. Our review showed that navigation provided a higher accuracy in the placement of pedicle screws compared with conventional methods. The superiority of navigation systems was obvious when they were applied to abnormal spinal structure. Although no strong in vivo evidence has detected significantly different pedicle screw placement accuracy among the three major navigation systems, meta-analysis revealed the variance in pedicle screw insertion accuracy with different navigation methods.

Abstract. Bone drilling manipulation often occurs in the orthopaedic surgery. By statistics, nowadays, about one million people only in Europe need such an operation every year, where bone implants are inserted. Almost always, the drilling is performed handily, which cannot avoid the * Corresponding author e-mail: george@imbm.bas.bg. Unauthenticated Download Date | 5/9/18 11:41 PM 52 G. Boiadjiev, R.

The question of subjective factor reduction has its answer -automatic bone drilling.The specific features and problems of orthopaedic drilling manipulation are considered in this work. The automatic drilling is presented according the possibilities of robotized system Orthopaedic Drilling Robot (ODRO) for assuring the manipulation accuracy, precision, reliability and safety.

Automatic bone drilling could entirely solve the problems that usually arise during manual drilling. An experimental setup was designed to identify bone drilling parameters such as the resistance force arising from variable bone density, appropriate mechanical drilling torque, linear speed of the drill, and electromechanical characteristics of the motors, drives, and corresponding controllers. Automatic drilling guarantees greater safety for the patient. Moreover, the robot presented is user-friendly because it is simple to set robot tasks, and process data are collected in real time.
