ABSTRACT
Objective: to evaluate the efficacy and safety of kyphoplasty combined with pulsed radiofrequency (PRF) applied to facet joints as a standard treatment for vertebral compression fractures.
Material and methods: multicenter, ambispective study with a retrospective phase (2014-2020) and a prospective phase (2021-2024), including 400 patients aged ≥ 50 years (67% women). Data collected included demographics, fractured levels, visual analog scale (VAS) for pain, Oswestry Disability Index (ODI), comorbidities, and complications. The procedure consisted of standardized percutaneous kyphoplasty followed by PRF. Variables were analyzed preoperatively, on postoperative day 1, and at 1, 3, and 6 months, then annually for up to 10 years.
Results: mean VAS pain scores decreased from 9.2 ± 0.7 preoperatively to 0.78 ± 0.68 on the first postoperative day, an absolute reduction of ~ 8.4 points (≈ 91% less pain, p < 0.001, paired t-test). The baseline ODI averaged 88.8% ± 6.5%; after the intervention, it dropped to 25% within 24 hours, with continued long-term improvement in functionality. Complication rates were low: adjacent fracture 8%, cement leakage 3%, and infection < 0%. No significant differences in outcomes were found based on diabetes, hypertension, obesity, or osteoporosis.
Conclusions: kyphoplasty combined with PRF provides immediate and sustained pain relief, significant functional improvement, and a favorable safety profile, establishing it as a standard therapeutic option for vertebral compression fractures.
