Technology Description
Researchers at Washington University in St. Louis have developed a system that uses lenticular arrays to better track pedicle screw placement during spinal fusion surgery. By enabling an accurate assessment of the screws’ locations, this system allows for computer-automated spinal rod bending.
Extenders using a step-locking hinge mechanism are placed on each pedicle screw, each containing a trackable marker. A more accurate system of screw tracking will ensure the spinal rod has the proper lordosis.
Stage of Research
The researchers have conceptualized and manufactured the screw tracking system, and in vivo accuracy testing has been performed.
