ABSTRACT
Objective:To compare Jack dilator-kyphoplasty (DKP) and balloon-kyphoplasty (BKP) for osteoporotic vertebral compression fracture (OVCF) in postoperative vertebral height loss and adjacent intervertebral disc degeneration.Methods:A total of 94 OVCF patients were treated and fully followed up at Department of Orthopaedic Surgery, The First Hospital Affiliated to Nanjing Medical University from May 2007 to October 2016. Of them, 30 were subjected to DKP and 64 to BKP. In DKP group, there were 18 males and 12 females, with an age of (72.4±9.2) years, a bone density of (-3.99±0.88) SD and a disease course of (0.7±0.4) months; in BKP group, there were 28 males and 36 females, with an age of (71.6±14.3) years, a bone density of (-4.08±0.63) SD and a disease course of (0.6±0.3) months. The 2 groups were compared in terms of change in the height of injured vertebrae, disc height index percentage (DHIP) and Pfirrmann grading of adjacent disc degeneration at preoperation, 2 days and 36 months after operation.Results:The 2 groups were comparable due to insignificant differences in their preoperative general data ( P>0.05). The anterior and middle heights of injured vertebrae and DHIP at postoperative 36 months were significantly lower than those at postoperative 2 days in both groups ( P<0.05). There was no significant difference between the 2 groups in DHIP at 36 months after operation (79.86%±4.48% versus 80.24%±6.85%) ( t=0.277, P=0.782). By the Pfirrmann grading, 36 and 84 patients had intervertebral disc degeneration in DKP and BKP groups respectively. There was no significant difference in the incidence of intervertebral disc degeneration between the 2 groups (60.0% versus 65.6%) (χ 2=0.560, P=0.454). Conclusions:In the OVCF treatment, DKP and BKP may potentially cause height loss of the injured vertebrae and degeneration of adjacent intervertebral disc, but no difference was found in disc degeneration between the 2 modes.
