O-ARM2® Equipment

In Spain, Barcelona Spine Center was the first institution to use the cutting-edge intraoperative imaging integration with an O-arm® System scanner and StealthStation S7 surgical navigation system. This Medtronic brand system makes it possible to perform surgical navigation with high-precision data, two-dimensional and three-dimensional images during operations in real time, increasing patient safety and the performance and efficiency of our surgical teams.

During each operation, surgeons can see multi-dimensional images and fluoroscopic images that allow them to see the patient’s anatomy in the operating position, monitor the status of surgery and verify intraoperative changes by means of a volumetric 3D image before the patient leaves the operating room. Thanks to this system, patients benefit from less invasive surgery, shorter operation time, faster recovery time and a better end result.


How does it work?

Image guided surgery is possible with real time images provided by surgical navigation systems that use radiological images. The software converts preoperative images from each individual patient and displays different views (axial, sagittal, coronal, view history, view probe). Image-guided surgery can upload CT and/or MRI images in DICOM format, and automatically or manually merge these images with images obtained by other means (CT, MRI, functional, angiography, DTI-post processing, PET images, etc.). Before surgery, the surgeon can create, store and simulate surgery using one or more surgical approaches. As an aid to visualization, the surgeon can also create and manipulate one or more 3D models of the patient’s anatomy (skin, cortex, tumors, vessels, ventricles, skull, etc.) and display the corresponding 2D views (axial, sagittal , coronal, approaches, probes). 3D models can be created automatically, manually or by contour plots.

During the operation, the system follows the position of special surgical probes located in or on the patient’s anatomy and continuously updates the position of the probe in these images (dynamic real-time recording).


Benefits for the patient

  • O-ARM® maximizes the surgical team’s possibility of performing minimally invasive surgery, which reduces patient trauma compared with open surgery techniques associated with increased muscle trauma and co-morbidity.
  • It also allows surgeons to apply minimally invasive techniques for surgery of spinal conditions: degenerative diseases, trauma, spinal tumors and deformities, such as scoliosis, which so far were not been able to benefit from these techniques.
  • It also provides enhanced real-time images of patients’ anatomy, allowing greater precision in the placement of prostheses, improving patient safety and ensuring more precise navigation during surgery to obtain the best results for the patient.
  • It facilitates the capture of intraoperative 3D images before closing the surgical incision, allowing the confirmation of correct placement of all elements and minimizing surgical complications and revisions.
  • In contrast to traditional intraoperative systems, all movements are robotic and managed by means of a simple control panel.
  • Its motorized system makes it possible to easily move the system from one operating room to another.
  • Its motorized repositioning reduces the need for manual movements and acquisition of additional images.
