Quantifying Surgical Plan Compliance
in Spinal Deformity Surgery

SpineYOYO is a prospective, multi-center clinical research project developing an AI-driven framework to objectively measure the deviation between pre-operative surgical plans and actual intraoperative execution in spinal deformity correction.

The Problem

Despite meticulous pre-operative planning, there is currently no standardized method to quantify how accurately a spinal deformity surgery follows the original plan. Surgeons rely on subjective post-operative assessment, and the literature shows significant discrepancy between planned and achieved correction.

Surgeons predict post-operative alignment accurately only 42% of the timeAkazawa et al., Spine Deformity (2023)
Research Aims
Aim 01

Stick2Plan Compliance Metric

Develop and validate a novel quantitative metric that expresses surgical plan adherence as a single percentage score through automated DICOM comparison.

Aim 02

AI-Powered Radiographic Analysis

Build an ensemble AI system for automated vertebral segmentation, Cobb angle measurement, and pedicle screw trajectory assessment from pre-op and post-op imaging.

Aim 03

Intraoperative Sensing

Integrate low-cost IMU/BLE inertial sensors for real-time angular guidance during instrumentation, enabling objective intraoperative deviation tracking.

Aim 04

Multi-Center Validation

Conduct a prospective clinical study across 3-5 centers to validate the Stick2Plan metric's reliability, reproducibility, and clinical significance.
