Abstract: Objective · To compare the clinical efficacy of cross puncture technique with traditional puncture technique in the treatment of osteoporotic vertebral compression fracture (OVCF). Methods · Patients with OVCF treated with percutaneous vertebroplasty (PVP) were selected. According to the puncture method, the patients were divided into cross puncture group and traditional puncture group, with 70 cases in each group. The clinical data, imaging parameters, pain score, dysfunction score, overall satisfaction and related complications of the two groups were compared before and after operation, and the clinical efficacy of the two groups was evaluated. Results · Compared with the traditional puncture group, the wedge angle in the cross puncture group decreased at 6 and 12 months after operation (both P=0.000), while the leading edge height increased (P=0.012, P=0.000). During the follow-up, there was no significant difference in pain score and dysfunction score between the two groups. Compared with the traditional puncture group, the proportion of the excellent and great grades (Odom standard) of patients in the cross puncture group was higher (P=0.000, P=0.003), and the incidence of vertebral collapse, kyphosis deformity and spinal stenosis were lower (P=0.000, P=0.002, P=0.031). Conclusion · At 6 and 12 months after operation of cross puncture PVP, the follow-up changes of wedge angle and leading edge height of vertebral body were smaller than those of traditional puncture technique, that is, more stable. The incidence of vertebral collapse was lower, and the overall satisfaction of the curative effect was higher.
