Abstract: BACKGROUND: The 3D printing guide technology has achieved good results in precise nail placement, but the application and research of 3D printed body surface guide plate with active registration localization combined with anatomical marker localization have not been reported.
OBJECTIVE: To investigate the clinical effect and safety of 3D printing percutaneous puncture guide assisted vertebroplasty in the treatment of osteoporotic vertebral compression fracture with active registration localization combined with anatomic marker localization.
METHODS: The clinical data of 50 patients with osteoporotic vertebral (T10-L2) compression fracture who met the inclusion criteria from October 2020 to June 2021 were analyzed. The patients were randomly divided into the observation group (25 cases) and the control group (25 cases). The observation group received percutaneous vertebroplasty assisted by 3D printing percutaneous puncture guide plate with active registration positioning combined with anatomical marker positioning. The control group received routine percutaneous vertebroplasty. The puncture positioning time, puncture number, fluoroscopy number, fluoroscopic exposure duration, and total operative duration were observed and recorded in the two groups when obtaining the optimal puncture location. Visual analogue scale score and Oswestry disability index were recorded before, 1 week and 3 months after surgery. Vertebral midline height and Cobb angle were compared before, 1 week and 3 months after operation between the two groups. Perioperative complications were recorded.
RESULTS AND CONCLUSION: (1) The total puncture time, puncture adjustment times, and fluoroscopy times in the observation group were lower than those in the control group, and the incidence of intraoperative and postoperative complications in the observation group was lower than that in the control group (P < 0.05). (2) Visual analogue scale score and Oswestry disability index in the same group at 1 week and 3 months after surgery were significantly lower than those before surgery (P < 0.05). Visual analogue scale score and Oswestry disability index were lower in the observation group than those in the control group at 1 week and 3 months after surgery (P < 0.05). (3) The number of cases of postoperative bone cement leakage in the observation group was significantly lower than that in the control group (X2=8.754, P < 0.05). (4) Above findings indicate that percutaneous vertebroplasty assisted by active registration combined with anatomic marker location can effectively simplify and optimize the surgical process, shorten the operation time and radiation exposure, improve the success rate of surgery, effectively reduce surgical complications, and improve the safety of percutaneous vertebroplasty.
