Abstract:
Objective To investigate the clinical efficacy of our self-designed sight used to guide thoracic vertebroplasty.Methods A retrospective analysis was conducted of the 52 patients (70 thoracic vertebrae) who had undergone percutaneous vertebroplasty (PVP) (n =36)or percataneous kyphoplasty (PKP) (n =34) of T1-T4 vertebral bodies at Department of Orthopaedics,The First Affiliated Hospital to Zhengzhou University form August 2012 to October 2013.The operation time,intraoperative bleeding,intraoperative radiation by C-arm roentgenography,and visual analogue scale (VAS) were compared between the patients whose surgery had been guided by our self-designed sight and those whose surgery had been not.Results All the patients were followed up for 18 to 36 months (average,22.3 months).Compared with those who had not used the sight,the patients who had used the sight incurred significantly shorter operation time (16.5 ± 3.2 min versus 26.5 ± 3.7 min),significantly less intraoperative bleeding (2.8 ± 1.3 mL versus 6.3 ± 1.7 mL) and significantly less radiation by C-arm roentgenography (5.6 ± 3.3 times versus 9.4 ± 3.1 times) (P ＜0.05).The VAS scores at postoperative 3 days and final follow-up were significantly decreased than the preoperative values in all the patients (P ＜ 0.05).There were no significant differences between the patients who had used the sight and those who had not in the the VAS scores at postoperative 3 days or final follow-up (P ＞ 0.05).Conclusions The upper thoracic PVP or PKP guided by our self-designed sight has theadvantages of short operation time,less intraoperative bleeding and less frequency of C-arm radiation.The sight is suitable for various vertebroplasties.
