ABSTRACT
Objective:
To evaluate the efficacy of unilateral puncture techniques in high-viscosity cement percutanueous vertebroplasty (PVP) in treatment of type I chronic symptomatic osteoporotic vertebral compression fracture (CSOVCF).Methods:
A retrospective case control study was conducted to analyze the clinical data of 119 patients with type I CSOVCF admitted to Honghui Hospital affiliated to Xi'an Jiaotong University School of Medicine from December 2013 to December 2016. There were 42 males and 77 females, aged 58-95 years [(79.2±15.6)years]. All patients had bone mineral density of -4.5--2.5 SD [(-3.9±0.2)SD] (T score). The fractured segments included L 1-L 2 in 56 patients and L 3-L 5 in 63. All patients were treated by high-viscosity cement PVP with the unilateral puncture of transverse process and superior articular process in unilateral group ( n=60) and by the bilateral puncture approach with the Magerl method in bilaleral group ( n=59). The operation time, cement injection volume, and intraoperative fluoroscopy frequency were recorded. The visual analogue scale (VAS), Oswestry dysfunction index (ODI), anterior height ratio of injured vertebrae and Cobb angle were measured before operation, at postoperative 1 day and at the last follow-up. The adjacent vertebral fracture, cement leakage and other complications were recorded.Results:
All patients were followed up for 12-48 months [(24.1±5.6)months]. The operation time in unilateral group [(21.5±6.5)minutes] was significantly shorter than that in bilateral group [(37.8±7.4)minutes] ( P<0.05). The cement injection volume in unilateral group [(4.2±0.7)ml] was less than that in bilateral group [(6.5±1.1)ml]( P<0.05). The intraoperative fluoroscopy frequency in unilateral group [(14.2±3.0)times] was less than that in bilateral group [(31.4±6.4)times] ( P<0.05). Both groups showed significant improvements in VAS, ODI, anterior height ratio of injured vertebrae and Cobb angle at postoperative 1 day and at the last follow-up compared with these before operation ( P<0.05), but there were no significant differences after operation between the two groups ( P>0.05). The incidence of adjacent vertebral fracture was 5%(3/60) in unilateral group and 8% (5/59) in bilaleral group ( P>0.05). Four patients (7%) had cement leakage in unilateral group and 11 patients (19%) in bilateral group ( P<0.05). No complications of wound infection, nerve injury or pulmonary embolism occurred.Conclusion:
Compared with Magerl bilateral puncture approach, high-viscosity cement PVP with unilateral puncture of transverse process and superior articular process in treatment of type I CSOVCF has advantages of shorter operation time, less trauma, less radiation exposure and lower cement leakage rate.
