Comparison of Kyphoplasty and Vertebroplasty for Treatment of Painful Osteoporotic Vertebral Compression Fractures

Abstract

Kyphoplasty and vertebroplasty demonstrated similar good clinical outcomes during the 12-month follow-up. Kyphoplasty offers a higher degree of spinal deformity correction and results in less cement leakage than vertebroplasty. The benefits of these relative merits need to be ascertained in future long-term studies.

A Randomized Trial Comparing Balloon Kyphoplasty and Vertebroplasty for Vertebral Compression Fractures due to Osteoporosis

“…6,44,45 With KAVIAR, 75% of patients with VP had postural reduction, accounting for deformity correction in the VP group, and this finding may explain less postoperative correction in VP (compared to BKP) reported in other studies. 8,40,41 The subsequent radiographic fracture rate is similar to that in another RCT 5,10 and is likely due to the high number of prevalent fractures at baseline, a potent risk factor. 13 This finding underscores the importance of additional therapeutic measures such as pharmacologics to help reduce fracture risk.…”

“…8 Nonrandomized comparisons show similar results. 40,41 Here, postsurgery kyphotic angulation correction was similar between groups. There was some loss of correction in both groups at 3 months; however, for VP, the trend was more loss, with a statistically significant 24-month difference between groups (Table 3).…”

Current concepts of percutaneous balloon kyphoplasty for the treatment of osteoporotic vertebral compression fractures: Evidence-based review

“…Of the remaining 187 citations, case series, review articles, publications describing novel basic technologies, and technique reports were eliminated. The remaining 14 studies, including 7 systematic reviews [18][19][20][21][22][23][24] and 7 controlled studies, [25][26][27][28][29][30][31] were saved and reviewed. The selection process is described in Figure 6.…”

In Not Only Vertebroplasty but Also Kyphoplasty, the Resolution of Vertebral Deformities Depends on Vertebral Mobility

“…[1][2][3][4][5][6][7][8][9] KP is a treatment procedure that was developed with the expectation that it would provide better resolution of vertebral deformities than VP because of the insertion and inflation of a balloon within the collapsed vertebral body. Although some reports show that the postoperative height restoration and kyphotic changes achieved by KP are significantly superior to those achieved by VP, [10][11][12][13] others report scarce differences in these outcomes between balloon KP and VP, [14][15][16] and no consensus has yet been reached. It has been reported that the presence of vertebral mobility associated with pseudoarthrosis of the fractured vertebral bodies greatly influences the postoperative height restoration and kyphotic changes after conventional VP [17][18][19][20] ; however, the influence of vertebral mobility on the outcomes of KP has been studied very little.…”
