Percutaneous vertebroplasty(PVP), among various other options,has become a mainstay in the management of osteoporotic compression vertebral fractures. The purpose of this article is to review complications arising from the procedure and describes methods to minimize them. Complications can be classified as mild,which may include a temporary increase in pain; transient hypotension and cement leakage in the intervertebral disc space or into paravertebral soft tissues, moderate, including infection; extravasation of cement into the foraminal or epidural space and severe such as cement leakage in the paravertebral veins, leading to pulmonary embolism, cardiac perforation, cerebral embolism or even death.

BACKGROUND: Vertebroplasty is not free from cement related complications. If an allograft is used as a filler, most of them can be averted. METHODS: Forty consecutive cases of osteoporotic vertebral fracture were divided into two groups by self-selection. The study and the control groups underwent vertebroplasty with fresh frozen allogeneic bone chips and bone cement, respectively. Clinical results were assessed at preoperation, postoperative day 1 and months 3, 6, and 12 by 10-grade visual analog scale (VAS), and radiological results were assessed at the same time by vertebral kyphotic angle (VKA) and local kyphotic angle (LKA). The results were compared within and between the groups. Survival function was analyzed. The criteria of an event were clinical or radiological deterioration versus pre-index surgery state. RESULTS: VAS was improved in the study group from 8.4 +/- 0.8 to 5.2 +/- 1.4, 6.4 +/- 1.2, 5.5 +/- 2.7, and 3.7 +/- 1.4 at postoperative day 1 and months 3, 6, and 12, respectively, and in the control group from 8.4 +/- 1.2 to 3.2 +/- 1.1, 3.2 +/- 1.7, 3.2 +/- 2.7, and 2.5 +/- 1.7, respectively (within group, p < 0.001; between groups, p < 0.001). VKA was improved in the study group from 18.9degrees +/- 8.0degrees to 15.2degrees +/- 6.1degrees (p = 0.046) and in the control group from 14.7degrees +/- 5.2degrees to 10.3degrees +/- 4.7degrees (p < 0.001) at postoperative day 1. LKA was not improved in the study group but was improved in the control group from 16.8degrees +/- 11.7degrees to 14.3degrees +/- 9.6degrees (p = 0.015). Correction angle was 2.7degrees +/- 4.6degrees, -7.9degrees +/- 5.3degrees, -7.2degrees +/- 5.2degrees, and -7.4degrees +/- 6.3degrees at postoperative day 1 and months 3, 6, and 12, respectively, in the study group and 4.3degrees +/- 3.7degrees, 0.7degrees +/- 3.6degrees, 0.7degrees +/- 4.2degrees, and 0.1degrees +/- 4.4degrees, respectively, in the control group. Correction loss was significant in both groups (p < 0.001) and more serious in the study group (p < 0.001). The 6-month survival rate was 16.7% in the study group and 64.3% in the control group (p = 0.003; odds ratio, 5.250). CONCLUSIONS: In treatment of osteoporotic vertebral fracture, fresh frozen allogeneic bone chips are not recommendable as a filler for its worse results than bone cement.

OBJECTIVE: To explore the risk factors of hidden blood loss in osteoporosis vertebral compression fractures during percutaneous vertebral augmentation. METHODS: From October 2018 to December 2019, 360 patients with osteoporosis vertebral compression fractures who received percutaneous vertebral augmentation were enrolled in this study. The factors analyzed included gender, age, surgical methods, disease course, height, weight, the operative segment, bone mineral density, amount of bone cement, operative time, percentage of height loss, percentage of vertebral height restoration, cement leakage, blood clotting function, preoperative and postoperative hemoglobin and hematocrit and other internal diseases. Total blood loss was calculated by Gross's formula, influential factors of the hidden blood loss were further analyzed by t-test, multivariate linear regression and one-way ANOVA analysis. RESULTS: Surgical methods, the operative segment, disease course, cement leakage, preoperative hemoglobin, cement leakage via the basivertebral and segmental vein were significantly correlated with hidden blood loss(P<0.05). CONCLUSION Patients with percutaneous kyphoplasty, two-level and multi-level surgery, the course of the disease beyond 6 weeks, cement leakage via the basivertebral and segmental vein, and lower preoperative hemoglobin had more perioperative hidden blood loss.
