ABSTRACT

OBJECTIVE:

We investigated the association between clinical and radiological results and assessed the radiological changes according to the distribution pattern and amount of injected cement after vertebroplasty.

METHODS:

Two hundred and one patients underwent vertebroplasty; of these, 15 were follow up for more than 2 years. For radiological analysis, we grouped the patients according to cement distribution as follows group 1, unilateral, unilateral distribution of cement; group 2, bilateral-uneven, bilateral distribution of cement but separated mass; and group 3, bilateral-even, bilateral single mass of cement. To compare radiologic with clinical results, we assessed the visual analogue scale (VAS) score, amount of injected cement, bone mineral density (BMD), postoperative and follow-up vertebral body compression ratios, and postoperative and follow-up kyphotic angles.

RESULTS:

There were 4 (26.7%) patients in group 1, 6 (40.0%) in group 2, and 5 (33.3%) in group 3. The mean VAS score was 5.2 preoperatively, 1.8 postoperatively, and 3.2 at 2-year follow-up. The 2-year follow-up compression ratio was better in patients with even distribution of injected cement (group 2 and 3) than group 1. However, it was not statistically insignificant (p>0.05). The follow-up kyphotic angle was more aggravated in the group 1 than in the other groups (p<0.05).

CONCLUSION:

Our study showed that vertebroplasty had a beneficial effect on pain relief, particularly in the immediate postoperative stage. The augmented spine tended to be more stable in the cases with increased amount and more even distribution of injected cement.
