ABSTRACT
Objective:To compare the efficacy of robot-assisted and conventional fluoroscopy-guided percutaneous vertebroplasty (PVP) combined with pediculoplasty in treating symptomatic chronic thoracolumbar osteoporotic vertebral fracture (SCOVF) without neurological symptoms.Methods:A retrospective cohort study was used to analyze the clinical data of 120 patients with thoracolumbar SCOVF without neurological symptoms, who were admitted to Honghui Hospital Affiliated to Xi′an Jiaotong University from January 2015 to January 2020. The patients included 34 males and 86 females, aged 63-85 years [(72.9±5.7)years]. All patients were treated with PVP combined with pediculoplasty. A total of 87 patients were treated with robot-assisted and C-arm X-ray machine guided puncture (robot group) and 33 patients with C-arm X-ray machine fluoroscopic-guided puncture (conventional group). The operation time, amount of bone cement injection and puncture accuracy were compared between the two groups. The results of vertebral body index, Cobb angle, visual analogue scale (VAS), and Oswestry disability index (ODI) were also compared before operation, at 1 day and 1 year after operation and at the final follow-up. Complications such as bone cement leakage and displacement were observed.Results:All patients were followed up for 24-36 months [(29.4±3.4)months]. The operation time was (85.2±10.5)minutes in the robot group, significantly longer than (37.2±3.7)minutes in the conventional group ( P<0.01). The amount of bone cement injection was (5.0±0.7)ml in the robot group, significantly less than (5.3±0.8)ml in the conventional group ( P<0.05). The puncture accuracy in the robot group was 95.4% (83/87), significantly higher than 81.8% (27/33) in the conventional group ( P<0.01). There were no significant differences in vertebral body index, Cobb angle, VAS or ODI between the two groups before operation (all P>0.05). The values of vertebral body index were 87.1±4.5, 86.9±4.3, 86.8±4.3 in the robot group at 1 day after operation, 1 year after operation and the final follow up, respectively, which were significantly higher than 83.6±4.4, 84.1±3.8, 84.4±3.9 in the conventional group (all P<0.01). There were no significant differences in Cobb angle or ODI between the two groups at 1 day after operation, 1 year after operation or the final follow-up (all P>0.05). The values of VAS were (2.9±1.0)points, (1.8±0.7)points, (1.8±0.7)points in the robot group at 1 day after operation, 1 year after operation and the final follow-up, respectively, which were significantly lower than (4.4±1.1)points, (3.1±0.8)points, (3.0±0.9)points in the conventional group (all P<0.01). The bone cement leakage occurred in 7 patients in the robot group [8.0%(7/87)] and in 10 in the conventional group [30.3%(10/33)] ( P<0.01). No delayed bone cement displacement [0.0%(0/87)] occurred in the robot group from 1 day after operation to the final follow-up, but 3 patients [9.1%(3/33)] were noted in the conventional group ( P<0.05). Conclusion:Both robot-assisted and conventional fluoroscopy-guided PVP combined with pediculoplasty have satisfactory effect for SCOVF patients without neurological impairment, but the robot-assisted one has the advantages of higher puncture accuracy, more satisfactory vertebral height recovery, more rapid pain relief, lower incidence of bone cement leakage and effective avoidance of cement displacement.
