Cement augmentation is an effective surgical treatment for osteoporotic compression fractures. There are several cement augmentation types. However, no studies have compared the safety and efficacy of different cement augmentation types for the treatment of compression fractures.
We performed this study to understand the efficacy of different cement augmentation methods on osteoporotic compression fractures.
The purpose of this study was to investigate the visual analog scale scores for pain, kyphotic angle, average body height, rate of cement leakage, and occurrence of adjacent vertebral compression fractures for each different cement augmentation type.
We retrospectively analyzed 354 patients with acute vertebral compression fractures. Visual analog scale scores for pain, kyphotic angle, average body height, rate of cement leakage, and occurrence of adjacent vertebral compression fractures were followed for 1 year and compared among different cement augmentation types.
In these 354 patients, all cement augmentation types showed significant improvement on pain scores, and no significant difference was noted between the groups (P = 0.325). Kyphoplasty with SpineJack performed best with regard to kyphotic angle reduction (P = 0.028) and vertebral body height restoration (P = 0.02). The rate of adjacent compression fractures was highest in the vertebroplasty group, with a statistically significant difference according to the Fisher’s exact probability test (P = 0.02). Although kyphoplasty with SpineJack, kyphoplasty with an intravertebral expandable pillar (IVEP), and vesselplasty resulted in lower rates of cement leakage than balloon kyphoplasty and vertebroplasty, the results might not be conclusive due to the small sample size.
Kyphoplasty with SpineJack has good outcomes in sagittal alignment correction. Vertebroplasty has the highest cement leakage rate and adjacent compression fracture occurrence.
In follow-up studies, more patients will be enrolled to validate and evaluate cement leakage rates in balloon kyphoplasty more accurately with SpineJack, vesselplasty, and an IVEP, and discuss more factors and postoperative outcomes.
