Treatment of Osteoporotic Vertebral Compression Fracture with Target-Anchored Vertebral Body Plasty
Objective: To analyze the clinical effect of target-anchored vertebroplasty and traditional percutaneous vertebroplasty on the treatment of osteoporotic vertebral compression fractures. Methods: 50 female New Zealand rabbits were selected for establishing the osteoporotic vertebral compression fracture model and divided into two groups, traditional group and target group followed by analysis of the anterior, posterior, and posterior vertebral body anterior height of the fracture and the injection volume of the bone cement at full filling, and to compare the ultimate compressive strength and stiffness differences between the two groups of specimens by biomechanical testing. Results: In traditional group, the operative time was significantly shorter than that of target group, and the intraoperative bleeding was significantly lower than that of target group (P < 0.05). The fracture area of target group was filled with sufficient bone cement, in the traditional group, 3 cases (12%) showed that bone cement was not filled in the fracture area (P < 0.05), but the total bone cement filling volume was not significantly different between the two groups, but the traditional group had more complete bone cement filling than the bone cement filling, the difference was statistically significant (P < 0.05). In addition, the anterior vertebral body height of each group was significantly higher than other observation points in the group (P < 0.05). However, the distribution of permeability and osmotic type of bone cement between the two groups was not significantly different (P > 0.05). Conclusion: Target-anchored vertebroplasty can improve the quality of clinical treatment of osteoporotic vertebral compression fractures, indicating that it might be a new surgical method.
