Clinical Report: Developing a Nomogram to Predict Incomplete Recovery After UBE

Overview

This study developed a nomogram to predict incomplete clinical recovery following unilateral biportal endoscopy (UBE) for lumbar disc herniation. Key predictors include increased body mass index (BMI), higher preoperative visual analogue scale (VAS-B) scores, elevated Oswestry disability index (ODI) scores, and the presence of facet joint osteoarthritis (FJOA).

Background

Lumbar disc herniation (LDH) is a common cause of low back pain and disability, often requiring surgical intervention when conservative treatments fail. Unilateral biportal endoscopy (UBE) offers a minimally invasive option for treating LDH, yet some patients experience incomplete symptom relief postoperatively. Understanding the predictors of such outcomes is crucial for optimizing surgical decision-making and improving patient recovery.

Data Highlights

Key Findings

• The nomogram identified four key predictors of incomplete recovery: increased BMI, higher preoperative VAS-B, elevated ODI, and presence of FJOA.
• The C-index for the training set was 0.86, indicating good predictive ability.
• The validation set demonstrated an even higher C-index of 0.92, confirming the model's reliability.
• Statistical analysis was performed using multiple logistic regression to identify independent risk factors.
• This model can assist clinicians in making informed preoperative decisions to optimize patient outcomes.

Clinical Implications

Clinicians can utilize this nomogram to identify patients at higher risk for incomplete recovery after UBE, allowing for tailored preoperative planning and enhanced postoperative care. Early identification of these risk factors may facilitate timely interventions to improve overall surgical outcomes.

Conclusion

The developed nomogram serves as a valuable tool for predicting incomplete clinical recovery after UBE for lumbar disc herniation, aiding in clinical decision-making and potentially improving patient outcomes.
