Location and Effect of Bone Cement in Percutaneous Vertebroplasty for Osteoporotic Vertebral Compression Fractures

In this study, the effectiveness and use of bone cement are thoroughly elaborated, and the role of bone cement on percutaneous vertebroplasty (PVP) fixed joints and its distribution on PVP are also elucidated. The aim of this study was to investigate the effect of unilateral and bilateral bone cement distribution on the clinical efficacy of PVP in the treatment of osteoporotic vertebral compression fractures (OVCF) of the thoracolumbar spine. A total of 60 patients with thoracolumbar OVCF (T11-L2) hospitalized in our hospital from January 2020 to January 2021 were studied. All patients had thoracolumbar OVCF. Under the guidance of the C-arm machine, unilateral PVP was performed. According to the distribution of bone cement across the midline, the patients were divided into two groups: the unilateral group (37 cases): bone cement was distributed on one side of the midline of the vertebral body, and the bilateral group (23 cases): bone cement was distributed on both sides of the midline. Visual analogue scale (VAS), vertebral height recovery values, and preoperative and postoperative Cobb’s angle were recorded at 3 days, 1 month, 3 months, and 6 months. The differences between the two groups were compared and analyzed to evaluate the clinical efficacy. There was a statistically significant difference in VAS scores between the two groups before and after surgery ( $P<0.05$ ), but there was no statistically significant difference in VAS scores between the two groups at 3 days, 1 month, 3 months, and 6 months after surgery ( $P>0.05$ ). There were statistically significant differences in vertebral height recovery value and Cobb’s angle between the two groups before and after surgery ( $P<0.05$ ).
