Summary
This systematic review found that current risk prediction models for new vertebral fractures after augmentation in elderly patients with osteoporotic vertebral compression fractures (OVCFs) have significant methodological limitations and high risk of bias, limiting their clinical use.
Area of Science:
- Orthopedics
- Geriatrics
- Medical Informatics
Background:
- Osteoporotic vertebral compression fractures (OVCFs) are common in the elderly.
- Vertebral augmentation is a common treatment for OVCFs.
- Predicting new vertebral fractures after augmentation is crucial for patient management.
Purpose of the Study:
- To systematically evaluate risk prediction models for new vertebral fractures post-vertebral augmentation in elderly OVCF patients.
- To summarize their modeling methods, predictors, performance, and quality.
Main Methods:
- Systematic review of studies reporting prediction models for new vertebral fractures after augmentation in elderly OVCF patients.
- Searched multiple databases from inception to January 2026.
- Assessed methodological quality and risk of bias using PROBAST.
Main Results:
- Included 24 studies with 29 models; all from China.
- Models showed AUCs from 0.648 to 0.990, but only 3 had external validation.
- All studies had high overall risk of bias, particularly in statistical analysis; limited external validation restricts clinical applicability.
Conclusions:
- Current risk prediction models for new vertebral fractures post-augmentation in elderly OVCF patients have significant methodological limitations and high risk of bias.
- These models are not reliable for routine clinical use and should be considered research tools.
- Standardized design, bias control, and external validation are needed for credible clinical models.
