PathKeeper's innovative navigation system provides surgeons with optimal control over the surgery. Its patented 3D real-time spine navigation technology yields sub-millimeter levels of surgical accuracy, enabling physicians to precisely place the surgical implants and significantly reduce the margin of error. Unlike most spinal surgical environments, it offers a radiation-free theater which benefits both the surgical staff and patient from. 


The system has been designed to be highly mobile for smooth transitioning between operating rooms and clinics and its competitive pricing makes it a viable alternative for any sized medical institution.  



Unsurpassed accuracy for optimal surgical screw placement


PathKeeper's spine surgery navigation system provides sub-millimeter accuracy. This resolution is possible since the technology is capable of continuously tracking each spinal vertebra in real-time, taking into account patient movement and surgeon manipulation. As a result, physicians can precisely track and place surgical tools with sub-millimeter levels of accuracy and safety.  

Current spinal navigation systems claim an accuracy level on the millimeter level by tracking the spine using preoperative spinal snapshots.  These systems use markers connected to a specific anatomical landmark and do not account for spinal movement throughout surgery leading to a wider margin of error.  


PathKeeper’s patented continuous anatomical tracking technology uses a preoperative CT scan to obtain the patient’s anatomy in 3D. It then integrates intra-operative images from the 3D camera and proprietary software to adjust the anatomical map in real-time. The anatomical map is updated continuously, and the surgeon can re-register as s/he chooses. The system also notifies the surgeon when anatomical movement of the patient is detected during surgery.  

Key benefits of the real-time tracking technology are that the navigation is not based on registration performed a while ago, and that surgeons do not need to pause the procedure in order to take snapshots to know what is going on in the body in real-time. Rather, the tracking system provides an accurate and continuous view of the procedure.


The PathKeeper system has been designed with a small form factor for easy mobility. As such, it can be easily integrated into any-sized operating room and does not get in the way of the surgical staff, surgical tools and operation room lighting.


The platform can be easily transferred between operating rooms and is an ideal solution for Ambulatory Service Centers (ASC) with multiple locations.


A key differentiator of the PathKeeper solution is that does not require a CT scan within the operating room, saving significant space within the operating theater. 


Ionizing radiation during spinal surgery is a primary concern that affects the health and safety of both the medical staff and the patient. The commonly used “free-hand” technique requires repeated fluoroscopy imaging to estimate the location and trajectory of the surgical screws. Similarly, almost all navigation systems require multiple C-Arm images and/or CT scans to guide the surgeon. 


Unlike these methods, PathKeeper’s solution uses only a preoperational CT scan and offers a completely safe and radiation-free operating environment.


PathKeeper’s breakthrough technology is competitively priced, making it an affordable option for hospitals and clinics of all sizes and budgets. The system is also highly cost-effective. Its quick setup and registration time reduces operative time, and its continuous tracking eliminates the need to pause the procedure. Since it does not require CT scanning during the procedure, the system eliminates the need for radiology equipment and support staff which saves costs as well. The system has a small footprint that does not take up a lot of space in the operating room and since it is highly mobile, it can be easily transferred between operating rooms.


Surgery planning has been proven to improve clinical outcomes in spine surgery, however, it has received limited adoption due to the complexity of current systems. Using proprietary clinical algorithms, PathKeeper has developed a surgery planning platform that is easy to learn and operate. 


The platform uses common resources such as pre-operative and intra-operative implant planning and cloud sharing between staff (including remote specialists) to ensure precise planning.


PathKeeper has successfully completed 10 cadaver labs ranging from the cervical vertebrae to the sacrum, having inserted an average of 6-8 screws in the process.
