Percutaneous vertebral-disc plasty for thoracolumbar very severe osteoporotic vertebral compression fractures

Abstract

Background: To compare the clinical outcomes and radiological parameters of patients undergoing percutaneous vertebroplasty (PVP) versus those undergoing percutaneous vertebral-disc plasty (PVDP) for back pain, segmental instability, and kyphosis due to thoracolumbar very severe osteoporotic vertebral compression fractures (vsOVCFs).Methods: 31 patients with thoracolumbar vsOVCFs were retrospectively reviewed. All the patients were divided into the PVP group and the PVDP group. The visual analogue scale (VAS), Oswestry Disability Index (ODI), local kyphosis angle, and disc height were recorded preoperatively and postoperatively.Results: Significant postoperative improvements on the VAS, ODI, and the local kyphosis angle (LKA) were shown, compared with the preoperative values in both groups (p < 0.05). The average VAS, ODI, and LKA for patients in the PVP group were increased compared to those in the PVDP group were observed at the last follow-up (p < 0.05). The DHA, DHP, and LKA were seen to be maintained in the PVDP group at the last follow-up (p > 0.05). In those parameters, the change was significantly lower in the PVDP group at the last follow-up. (p <0.05).Conclusions: PVDP may be a feasible and effective technique for the treatment of very severe OVCFs, that can restore intervertebral height, provide segmental stabilizing and improve kyphosis in the short term.
