A Decision Tree Algorithm to Predict Postoperative Kyphosis After Cervical Laminoplasty for Cervical Spondylotic Myelopathy

Key Points

To identify the risk of postoperative kyphosis (PLK) after cervical laminoplasty using a decision tree algorithm.
Utilized a decision tree algorithm
Analyzed radiographical predictors
Examined O-C2 angle and C2-C7 angle as predictive indicators.
Identified key radiographic indicators for PLK
O-C2 angle and C2-C7 angle are pivotal in risk evaluation
Achieved high metric performance in identifying PLK risk.

Abstract

Radiographical predictors identified the risk of PLK with high metric performance. The O-C2 angle, and C2-C7 angle may be pivotal radiographic indicators to evaluate the preoperative risk of PLK.
