SpineGuard SA Reports Advancement in Ultrasound‑Based Spine Surgery Guidance
SpineGuard SA, a French medical‑device company listed on the NYSE Euronext Paris, announced that a doctoral thesis presented on 11 December in Paris confirmed the feasibility of its newly patented ultrasound robot‑assisted technology. The study, conducted by PhD student engineer Andrés Pérez Velásquez in collaboration with the LIB and ISIR laboratories of Sorbonne University, demonstrated that the system can determine the entry point and pedicle trajectory from the posterior surface of the spine without the use of X‑ray imaging. The technology is positioned as a complement to SpineGuard’s existing DSG (Dynamic Surgical Guidance) local conductivity sensing platform, which already provides real‑time, X‑ray‑free guidance for bone‑implant placement.
Deputy CEO and co‑founder Stéphane Bette commented that the thesis represents the second scientific validation of SpineGuard’s ultrasound approach, following the company’s presentation at the CFA Congress in April. He emphasized that the new method allows the determination of drilling parameters before the DSG sensor drill bit contacts bone, thereby enabling automatic breach detection validated in previous studies.
The announcement follows a recent capital increase. On 16 December, SpineGuard completed a €1.2 million gross capital raise by issuing 10,705,794 new shares, thereby maintaining a priority period for the existing shareholders. Prior to the issuance, the company’s share capital comprised 78,509,157 shares; after the increase it stands at 89,214,951 shares. The capital raise is expected to support ongoing research and development, as well as potential regulatory filings for the ultrasound technology.
Financially, SpineGuard’s share price closed at €0.1088 on 15 December 2025, with a 52‑week high of €0.3195 and a low of €0.0755. The market capitalization is approximately €10.7 million. The company’s price‑earnings ratio remains negative at –2.365, reflecting its current investment‑heavy phase.
SpineGuard’s product portfolio includes the PediGuard family of drilling instruments (straight, curved, cannulated, psifguard, and threaded variants) and the DSG smart screw, which facilitates single‑step screw placement. In addition, the DSG Connect app collects and visualizes sensor data during pedicle drilling, and the company offers DSG solutions for orthopedic robots and dental implantology.
The ultrasound‑driven trajectory determination is expected to enhance the safety and precision of spinal surgeries while reducing radiation exposure, aligning with industry trends toward minimally invasive, image‑free procedures.
