PARIS & BOULDER, Colo.–(BUSINESS WIRE)–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 study in Japan quantifying DSG’s performance, the 19^th peer review publication worldwide on its technology.

Keri George, Director of Clinical Research & Education at SpineGuard, said: “It is exciting to see Japanese surgeons embracing the DSG innovative technology to achieve better surgical outcomes in such challenging spinal deformity cases.”

Study Summary

A retrospective collection by Dr. Takashi Yurube from the Department of Orthopaedic Surgery, Kobe University et al, that involved twenty-one patients with syndromic/neuromuscular scoliosis. Patients who underwent spinal fixation surgery were divided into two groups, one had fixation using the SpineGuard DSG technology; the other one without it.

The results between the two groups demonstrated a difference that was statistically significant in all three objectives: pedicle abandonment, screw placement accuracy, and perforation distance. In all three objectives the DSG group showed superior results.
