Cervical screw guidance

Regulatory News:

SpineGuard (Paris:ALSGD) (FR0011464452 – ALSGD), an innovative company that deploys its DSG® (Dynamic Surgical Guidance) sensing technology to secure and streamline the placement of bone implants, announced today the first clinical publication in Japan for its DSG technology.

This technical note published in Neurologia medico-chirurgica (the official peer-reviewed scientific journal of the Japan Neurosurgical Society) presents the clinical usefulness of PediGuard for an optimal positioning of bi-cortical screws in the lateral mass of the 1st cervical vertebra. These screws require an extremely precise positioning in order to avoid the vertebral artery as well as the internal carotid artery.

Stéphane Bette, CEO of SpineGuard, said: “It is the first scientific publication about our DSG technology in Japan, the 2nd largest market worldwide in our sector1. Furthermore, in a degenerative cervical spine application that requires extreme precision and sensitivity to screw placement, a specialty for Japanese surgeons due to the prevalence of such pathologies in this country. We are thus very happy about this 15th peer-reviewed journal publication documenting the clinical value of our DSG Technology in Spine. It strengthens the solid base of clinical evidence in support of our DSG technology that we are determined to deploy throughout new and promising clinical applications. We are actively working with the venture bank Healthios Capital Markets in order to find significant industry partnerships and generate growth and value for our shareholders.”

Dr. Hiroto Kageyama, Assistant Professor of neurosurgery at Hyogo College of Medicine, Nishinomyia, Hyogo, Japon adds: “We found the PediGuard device useful in our practice for the insertion of C1 lateral mass screws because it is easy to detect the anterior cortical wall of the Atlas on the basis of its auditory signal. After measuring the actual probe length, the screw length can be decided and the bicortical screwing can be performed safely and tightly.”
