[APPLICATION OF HIGH VISCOSITY BONE CEMENT IN UNILATERAL PUNCTURE PERCUTANEOUS VERTEBROPLASTY FOR TREATMENT OF FRESH...

Area of Science:

• Orthopedics
• Neurosurgery
• Radiology

Background:

• Osteoporotic vertebral fractures are a significant cause of morbidity in the elderly.
• Percutaneous vertebroplasty (PVP) is a minimally invasive treatment option.
• High viscosity bone cement offers potential advantages in PVP procedures.

Purpose of the Study:

• To evaluate the effectiveness of high viscosity bone cement in unilateral puncture PVP for osteoporotic vertebral fractures.
• To assess the technique's impact on pain, spinal alignment, and complication rates.
• To discuss surgical skills for preventing bone cement leakage.

Main Methods:

• A cohort of 82 elderly patients with fresh thoracolumbar vertebral fractures underwent unilateral pedicle puncture PVP using high viscosity bone cement.
• Pre- and post-operative assessments included pain visual analogue scale (VAS), Cobb angle, and vertebral body height compression ratio.
• Data on operation time, fluoroscopy time, blood loss, hospitalization, and bone cement leakage were recorded.

Main Results:

• The procedure demonstrated a low bone cement leakage rate (7.3%) with no nerve damage.
• Significant improvements were observed in VAS scores (reduced from 8.8 to 1.3), Cobb angle (reduced by 9.73°), and vertebral body height (increased to 67.8%).
• Average operation time was 16 minutes, fluoroscopy time 48 seconds, and hospitalization 3 days.

Conclusions:

• Unilateral puncture PVP with high viscosity bone cement is an effective treatment for osteoporotic vertebral fractures.
• The technique leads to significant pain relief, improved spinal alignment, and a low complication rate.
• This approach offers a safe and efficient option for managing these fractures.
