Abstract:
OBJECTIVE:To evaluate the effect of different bone cement injection methods during percutaneous vertebroplasty(PVP) on vertebral morphology and cement diffusion.
METHODS:The clinical data of 52 patients with single-segment osteoporotic vertebral compression fracture treated from January 2016 to December 2017 were retrospectively analyzed. The patients were divided into hydraumatic group (28 cases) and pusher group (24 cases) according to bone cement injection method during PVP. By comparing visual analogue scale(VAS), height of anterior vertebral body, compression ratio, kyphosis angle before and after operation and analyzing filling ratio of bone cement in the first 1/3, median line and back 1/3 of the vertebral body in lateral X-rays and the conditions of bone cement diffusion in AP X-rays were to evaluate the effect of different bone cement injection methods on vertebral morphology and cement diffusion.
RESULTS:Postoperative VAS was obviously improved in all patients and hydraumatic group was better than pusher group(<0.05). Postoperative height of anterior vertebral body, compression ratio and kyphosis angle obviously restored in all patients while there was no significant difference between two groups(>0.05). There was no significant difference in filling ratio of bone cement in the first 1/3 and median line of the vertebral body by lateral X-ray films between two groups(>0.05), but in the back 1/3 of the vertebral body filling ratio of bone cement in hydraumatic group was better than in pusher group(<0.05). The distribution of bone cement from AP X-ray films were more significant in hydraumatic group(<0.05).
CONCLUSIONS:Hydraulic delivery vertebroplasty (HDVP) has better clinical efficacy and it can guarantee sufficient distribution of bone cement into the fractured vertebra and preferably restore the morphology of vertebral body, which is worthy of clinical application.
