Augmedics declared the first successful application of its revolutionary xvision Spine System in Spinal surgery in the U.S.

John Hopkins University surgeons applied the system in a critical spinal surgery operation.

Xvision is the original Augmented Reality Guidance System, designed for surgery. It enables surgeons to experience the visual representation of the spinal analysis of the patient, in 3D.

This happens during the operation and gives the experience of “x-ray optics” and further aids in the accurate navigation of tools and implants. This is all done while viewing straight at the patient, instead of a digital screen.

The vision Spine System uses the best techniques of operational navigation systems and further advances them to reach the necessities of surgeons. Hence, it provides surgeons with technical assurance and precision during surgery.

How did surgeons use the xvision Spine System in surgery?

Specifically, the surgery was posterior lumbar decompression, with the correction of slipped vertebrae (spondylolisthesis), and fusion. Surgeons at The John Hopkins Hospital performed the surgery on the 8th of June.

The surgeons involved in the surgery were-

  • Director of Neurosurgery Spinal Fusion Laboratory, Dr. Timothy Witham
  • Director of Spine Tumor and Spine Deformity Surgery, Dr. Daniel Scuibba
  • Resident at Neurological Surgery, Dr. Camilo Molina

Founder and CEO of Augmedics, Nissan Elimelech, explained the revolution made in spinal surgery. Elimelech continued that this is the start of a new way of performing surgery.

This will provide surgeons with added precision, control, adequate and relevant information, with the addition of technological confidence. This will consequently give surgeons, maximum safety, and efficiency.

An important clinical need

Every year, almost 1.62 million spinal surgeries are performed in the U.S. Moreover, most of these are conducted using a conventional method which can cause sub-optimal outcomes.

  • 31% of all freehand surgeries, end with incorrect screw positioning.
  • 2.3% of all freehand surgeries, end with neurological difficulties owing to screw malposition.
  • 3% need reoperation within a period of 1 month to return the position of the screws. This potentially results in further complications related to the operation.

Surgical navigation systems notably enhance the results. The improved accuracy results in an over 95% success rate. These systems showed a 50% reduction in screw insertion time, providing a 92% reduction in X-ray radiation.

Although, 9% of surgeons (spinal surgery) use these systems regularly while 66% never use them. Several factors contribute to this.

  • Surgeons consider them inconvenient and uncomfortable to use
  • The systems do not match the demands of surgeons which includes time efficiency, easy use, etc.
  • They mislead specialists from their patients as it requires them to focus on a digital screen usually located at the patient’s feet.

How it works

In an attempt to acknowledge the demands, the xvision Spine System has a transparent headset which also consists of all the constituents of a conventional navigation system.

This has the utmost precision in real-time when concluding the location of the surgical tools. Moreover, it has a virtual trajectory that is superimposed on the CT data of the patient.

In the least invasive methods, the data of 3D navigation is propelled upon the retina of the surgeon via the headset. This enables the surgeon to focus on the patient and the data of navigation simultaneously, with no interruptions of a digital screen during the surgery.

They intend the system to change the traditional method of surgery. This will provide faster, safer, and easier surgeries with improved precision, visualization, and control. A cadaver study showed 98.9% precision in screw placement, with the help of the xvision Spine System.

At the end of last year, Augmedics declared the clearance from the U.S. Food and Drug Administration (FDA) and the launch of the xvision Spine System (XVS) in the U.S. The xvision is currently on sale in the U.S., with future sales of the headset.
