Abstract:
Objective:To investigate the clinical efficacy of percutaneous kyphoplasty (PKP) assisted by intuitive visual navigation orthopaedic surgery robot in the treatment of osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective analysis was conducted in Peking University Third Hospital from June 2021 to November 2022, 78 patients with OVCF were treated by the intuitive visual navigation orthopaedic surgery robot or freehand surgery with a "C" arm X-ray machine. According to the method of puncture, they were divided into robot group and freehand group. In the robot group, there were 36 cases, including 7 males and 29 females, aged 74.50±5.87 years, 32 cases of single vertebral fractures, 4 cases of double vertebral fractures, 1 case of T 8, 2 cases of T 10, 2 cases of T 11, 11 cases of T 12, 10 cases of L 1, 8 cases of L 2, 2 cases of L 3, 3 cases of L 4, and 1 case of L 5. Bone mineral density T value was -2.94±0.50; In the freehand group, there were 42 cases, including 9 males and 33 females, aged 72.86±8.84 years, 36 cases of single fracture and 6 cases of double fracture, 1 case of T 6, 2 cases of T 7, 3 cases of T 11, 9 cases of T 12, 8 cases of L 1, 9 cases of L 2, 5 cases of L 3, 6 cases of L 4, and 5 cases of L 5. Bone mineral density T value was -3.00±0.50. The effectiveness evaluation indexes of the two groups were compared, which included surgery duration, X-ray fluoroscopy times, hospitalization time, lumbar pain visual analogue scale (VAS), Oswestry disability index (ODI) and height of fractured anterior vertebrae (HFAV). Results:Both groups of patients successfully received surgical treatment. The mean operating time of the robot group was 33.44±2.50 min, which was significantly longer than that of the free hand group, which was 29.69±2.40 min ( t=6.491, P<0.001). Meanwhile, the intraoperative blood loss of the robot group was 3.54±0.89 ml, which was significantly less than that of the freehand group, which was 6.72±1.89 ml ( t=9.110, P<0.001). In terms of radiographic fluoroscopy times, the average of the robot group was 26.81±7.76 times, which was significantly less than the freehand group's 42.61±6.62 times ( t=9.294, P<0.001). The postoperative vertebral front edge height in the free hand group was 18.64±0.32 mm and in the robot group was 18.79±0.36 mm. The difference was not statistically significant ( t=2.673, P=0.067). All patients were followed up for 8.3±2.9 months (range, 6-13 months). The VAS scores of low back pain in the two groups at 1 day and 6 months after operation were significantly improved compared with those before operation ( P<0.05), and there was no significant difference between the two groups in VAS score after operation ( P>0.05). Six months after surgery, the ODI of the free hand group and the robot group were 11.67%±2.13% and 12.11%±2.33%, respectively. The ODI scores of the two groups were significantly lower at 6 months postoperative follow-up than that before surgery, and the postoperative follow-up at all had significant differences compared with that before surgery ( P<0.05), and there was no difference between the two groups in postoperative ODI scores ( P>0.05). No obvious bone cement leakage was found in all patients during operation. Conclusion:Compared with the traditional C-arm X-ray for PKP treatment of OVCF by free hand, intuitive visual navigation orthopedic robot can safely and effectively assist in the completion of the operation process, and has the advantages of less intraoperative blood loss, fewer fluoroscopy times.
