Background: Osteoporotic vertebral compression fractures (OVCF) seriously threaten the health of the elderly. Balloon dilatation percutaneous kyphoplasty (PKP) is currently one of the most commonly used methods for the treatment of OVCF in the elderly. Objective: This study aimed to explore the clinical effectiveness of PKP with unilateral balloon infusion of different doses of bone cement for treatment of OVCF in the elderly. Methods: The data of 36 elderly patients with OVCF treated with balloon dilatation PKP between August 2019 and August 2020 were retrospectively analyzed. According to volume of bone cement infused, the patients were separated into two groups: a small-dose group (1.8-3.0 mL of bone cement) and a conventional-dose group (3.5-6.0 mL of bone cement). Anterior vertebral body height and pain relief (assessed using a visual analog scale) before and after the operation were measured, and the differences between the two groups were analyzed. Results: Both groups had significant decrease in pain after PKP treatment (p < 0.05) in both groups). Restoration of vertebral body height was also successful in the two groups. Bone cement leakage rate was significantly lower in the low-dose group than in the conventional-dose group (p < 0.05). Conclusion: PKP with infusion of low dose of bone cement can achieve satisfactory restoration of vertebral height and relieve pain, while significantly reducing the risk of bone cement leakage.
