“…Thus, the results obtained by Garfin [15] indicate that in patients with a baseline loss of height equivalent to over 15% of the estimated normal value, the favorable effects of the technique only reach statistical significance in the case of fractures less than 60 days old. On the other hand, the results of a prospective study [10] specifically contrasting the results of BK in acute VCFs (defined as being less than 10 weeks [4,10,13,18,21,42,53,58] that consider the absolute value of the Cobb angle show the latter to decrease after kyphoplasty, though the mean reduction varies between )1.8°and )9.9°. The combined examination of the studies [4,10,13,18,42,53] that contribute data amenable to analysis confirms that following BK, the absolute value of this angle decreases significantly (Fig.…”
