“…However, Rousseau et al performed a dosimetric comparison in experimental conditions. 21 The authors found an effective dose related to 3D of 2.41 and 0.35 mSv with the O-arm and Surgivisio device, respectively, and an effective dose related to 2D of 1.54 and 0.30 mSv, respectively. They also reported that organ doses were 5 to 7 times higher with the O-arm in comparison with the Surgivisio device, which followed a trend that aligned with our results.…”

Navigated Cementoplasty With O-Arm and Surgivisio: An Ambispective Comparison With Radiation Exposure

Background: Vertebral compression fractures (VCF) are usually treated by cementoplasty. Computerized navigation allows more accurate surgery without additional imaging acquisition for guidance and related radiation exposure. New technologies trend to optimize the irradiation for patients and surgeons. The objective was to investigate the radiological results and radiation exposure of O-arm navigation compared with the all-in-one 2-dimensional/3dimensional (2D/3D) Surgivisio device in navigated cementoplasty procedures.Methods: Patients in the O-arm group comprised an O-arm prospective cohort as well as previous patients. Operations for VCF by navigated cementoplasty took place over 18 months. Patients in the Surgivisio group were the first patients operated on using Surgivisio and were prospectively recruited. Demographic, operative, and irradiation data were collected, as well as the image quality subjectively evaluated by the surgeon. The vertebal filling was evaluated using the Garnier classification and quoted as satisfactory, acceptable, or poor. The effective dose in millisievert (mSv) was calculated for radiation exposure estimation, and the absolute risk of cancer (AR) in percent equivalent to a wholebody irradiation was also calculated.Results: A total of 123 patients were included: 62 in the O-arm group and 61 in the Surgivisio group. A total of 166 vertebrae were analyzed. Compared with the Surgivisio group, the effective dose was significantly higher in the O-arm group, with a mean of 11.47 vs 1.14 mSv, respectively (P < 0.001). The 2D part of the effective dose received by the surgeon was significantly higher in the O-arm group, with an average of 2.25 vs 0.47 mSv, respectively (P < 0.001). Overall AR followed the same trend, with a mean of 4.9 × 10 -4 % in the O-arm group and 5.7 × 10 -5 % in the Surgivisio group (P < 0.001). Operative time was significantly higher in the O-arm group (34.52 vs 30.12 minutes respectively, P = 0.03). Image quality was similarly sufficient in 3D, but in 2D, image quality was significantly better in the O-arm group (P = 0.01). Vertebral filling was significantly better in the O-arm group, with 100% of results reported as satisfactory and acceptable versus 85% in the Surgivisio group (P < 0.001).Conclusions: The O-arm delivered a 10-times higher effective dose during navigated cementoplasty in comparison with the Surgivisio device. The O-arm also had a longer operative time, but it had better image quality and radiological results.

“…Voltage is higher in standard O-arm settings in comparison with the Surgivisio device, leading to higher level of irradiation. 21 Higher effective dose and better image quality in 2D mode for the O-arm can be explained by its settings, with a standard 30 pulses per second. Surgivisio produces 8 pulses per second in 2D mode.…”

The aim of this paper is to describe a protocol that simulates the spinal surgery undergone by adolescents with idiopathic scoliosis (AIS) by using a 3D-printed spine model. Patients with AIS underwent pre- and postoperative bi-planar low-dose X-rays from which a numerical 3D model of their spine was generated. The preoperative numerical spine model was subsequently 3D printed to virtually reproduce the spine surgery. Special consideration was given to the printing materials for the 3D-printed elements in order to reflect the radiopaque and mechanical properties of typical bones most accurately. Two patients with AIS were recruited and operated. During the virtual surgery, both pre- and postoperative images of the 3D-printed spine model were acquired. The proposed 3D-printing workflow used to create a realistic 3D-printed spine suitable for virtual surgery appears to be feasible and reliable. This method could be used for virtual-reality scoliosis surgery training incorporating 3D-printed models, and to test surgical instruments and implants.

Image-Guided Interventional Robotics: Lost in Translation?

2022

View full text Add to dashboard Cite

Interventional robotic systems have been deployed with all existing imaging modalities, in an expansive portfolio of therapies and surgeries. Over the years, literature reviews have painted a comprehensive portrait of the translation of the underlying technology from research to practice. While many of these robots performed promisingly in pre-clinical settings, only a handful of them managed to evolve further, and break through the commercialization boundary, and even fewer reached a wide-scale adoption. Despite the undeniable success of service robotics in general, and particularly in some sophisticated medical applications, image-guided robotics' impact remained modest compared to other surgical areas, especially laparoscopic minimally invasive surgery. This article aims to embrace the stateof-the-art on one hand, and to provide a comprehensive narrative to the situation described, to support future system developers and facilitating the translation from scientific research to applied clinical technology development.
