ABSTRACT
STUDY DESIGN:
This is a retrospective, case-controlled study.OBJECTIVE:
We wanted to evaluate the efficacy of lower-pressure percutaneous vertebroplasty (LP-PVP) using larger-diameter cement fillers for treating osteoporotic vertebral compression fracture (VCF). SUMMARY OF THE LITERATURE REVIEW Despite the popularity of conventional PVP(C-PVP), critical complications associated with cement leakage have been widely reported due to the inadequate viscosity of flabby cement. MATERIALS ANDMETHODS:
With excluding Kummell's disease, 23 VCF's were treated with LP-PVP using 2.8mm-diameter cement fillers, 51 VCF's were treated with kyphoplasty(KP) using the same size of cement fillers and 19 VCF's were treated with C-PVP using 1.4mm-diameter biopsy needles. The clinical and radiographic results along with the complications were investigated for more than one year.RESULTS:
The visual analogue scale (VAS) was improved in all the groups. The infused cement volume was 5.9+/-1.6ml for the LP-PVP, 5.9+/-1.9ml for the KP and 3.5+/-1.0ml for the C-PVP (p=0.000). The collapsed vertebral height was restored by 10.8+/-10.3%, 13.0+/-12.7% and 4.7+/-7.6%, respectively, in each group (p=0.000) with a reduction loss of 2.1+/-1.8%, 1.1+/-1.4% and 5.9+/-4.2%. respectively, in each group (p=0.000) at follow-up. These was a reduction of the vertebral kyphotic angle by 3.0+/-4.0degrees, 3.7+/-4.4degrees and 4.2+/-4.4degrees, respectively, in each group (p=0.528) with reduction loss of 1.0+/-0.9degrees, 0.1+/-1.7degrees and 3.5+/-2.8degrees, respectively, in each group (p=0.000). There was a reduction of the regional Cobb's angle by 4.3+/-2.6degrees, 3.1+/-4.7degrees and 2.9+/-3.8degrees, respectively, in each group (p=0.184) with a reduction loss of 3.6+/-4.5degrees, 0.1+/-1.5degrees and 1.0+/-4.1degrees, respectively, in each group (p=0.000). Extravasation of cement was noticed in 6 cases (26.1%) of LP-PVP, in 14 cases (27.5%) of KP and 4 cases (26.1%) of C-PVP (p=0.689). No cases of additional VCF happened for the LP-PVP, eight cases of additional VCF happened (15.7%) for the KP and one case of additional VCF happened (5.3%) for the C-PVP (p=0.030).CONCLUSION:
The LP-PVP showed clinically and radiologically results that were similar to those of KP with a higher amount of infused cement volume compared to that of C-PVP. LP-PVP is thought to be effective for the clinical and radiolographic aspects and to have fewer complications for the treatment of osteoporotic VCF.
