Analysis of Risk Factors for New Vertebral Fracture After Percutaneous Vertebroplasty

Area of Science:

• Orthopedics
• Neurosurgery
• Radiology

Background:

• Low-energy vertebral compression fractures pose a significant socioeconomic challenge in the elderly population.
• Percutaneous vertebroplasty is a common treatment for painful vertebral fractures, but new fractures are a known complication.
• Reported rates of new vertebral compression fractures post-vertebroplasty range from 8% to 52%.

Purpose of the Study:

• To investigate epidemiological and technical factors associated with new vertebral compression fractures after percutaneous vertebroplasty.
• To compare patients who developed new fractures with those who did not, following the procedure.

Main Methods:

• Retrospective analysis of 90 patients (30 with new fractures, 60 controls).
• Comparison of epidemiological and technical variables between the study and control groups.
• Level of evidence: III.

Main Results:

• The study group (new fractures) showed a higher mean cement percentage (40.3%) compared to the control group (30.5%).
• Initial vertebral kyphosis was significantly greater in the study group (15°) versus the control group (9°).
• No significant differences in epidemiological factors were observed between the groups.

Conclusions:

• Increased cement volume injected during percutaneous vertebroplasty is associated with a higher risk of new vertebral compression fractures.
• Greater initial vertebral kyphosis is also a risk factor for developing new fractures after the procedure.
