A nomogram for predicting residual low back pain after percutaneous kyphoplasty in osteoporotic vertebral compression fractures
Authors' conclusion
The risk prediction model has good predictive performance and clinical practicability, which can provide a certain basis for clinical decision-making in patients with OVCFs.
Study context
- Population
- Patients with osteoporotic vertebral compression fractures (OVCFs) who underwent percutaneous kyphoplasty (PKP) at the authors' hospital, July 2019 to July 2020 (development); January 2021 to October 2021 (temporal validation)126 in temporal validation
- Participants
- 281 patients
- Outcome
- Residual low back pain after PKP (risk prediction model)

Main finding
As reported in the abstract
Independent risk factors for residual low back pain
- Independent risk factors: Preoperative bone mineral density (pre-BMD), smoking history, thoracolumbar fascia injury (TLFI), facet joint injury (FJI) and incomplete cementing of the fracture line (ICFL)
- P < 0.05
Observational data: associations, not effects.
