3D Robotic Spine 'Twin' Offers Way to Preview Surgical Procedures

Surgeons consult a tablet computer during spinal surgery.

Results of the study showed that the soft magnetic sensor array system is capable of classifying the five different postures of the spine with 100% accuracy.

Researchers at Florida Atlantic University (FAU) and the University of Virginia have designed a robotic "twin" of a human spine so surgeons can predict how interventions play out before surgery.

The three-dimensionally-printed cervical spine replica was modeled from a computed tomography scan, and features an artificial disc implant and a soft magnetic sensor array.

A robotic arm flexes and extends the replica while the sensor array tracks intervertebral loads to classify spine posture with four machine learning algorithms.

The algorithms were able to classify five distinct postures with 100% accuracy.

FAU's Chi-Tay Tsai said use of the replica could "potentially reduce the rates of complication and failure of artificial disc implantation."
