A Novel Jig to Assist Accurate Insertion of S2AI Screw

The University of Hong Kong Background
S2-Alar-Iliac (S2AI) screws provide strong iliolumbar fixation for spinal and pelvic fixation surgeries. S2AI screws is gaining in popularity with long spinal fusion constructs extending into the pelvis. The modern insertion method involves large amount of radiation exposure. There is a need to develop a tool to reduce fluoroscopy time and radiation dosage. 
Technology Overview
The simple orthopedic surgical tool can be used in different operation room conditions with or without robotic navigation. With simple training to handle the jig, insertion using this jig can reach a comparable result as using robotic navigation for insertion.
Stage of Development
Completed validation study using cadaver. 

Benefits

Simple targeting device for S2AI screw insertion 
Reduce radiation exposure to patients and surgeons 
Improved procedural time 

Applications
 Spinal and Pelvic Fixation Surgeries
