Purpose: To investigate the clinical effect of percutaneous kyphoplasty (PKP) guided by computed tomography (CT) combined with the three-dimensional coordinate guidance system on the treatment of osteoporotic vertebral compression fracture (OVCF). Methods: 32 cases of OVCF in the elderly admitted to our hospital from October 2019 to March 2021 underwent CT-guided PKP combined with the three-dimensional coordinate guidance system, and 36 vertebrae were treated. The patients’ VAS pain scores (visual analog scale) and ODI (Oswestry disability index) were observed after surgery, and the paired t-test was used to compare these indexes. Results: The 36 vertebrae that were treated with CT-guided PKP combined with the three-dimensional coordinate guidance system underwent unilateral pedicle puncture according to the path planned by CT images. With the ideal position of the puncture needle and a high success rate of puncture, the puncture time was 1.2–2.6 minutes, with an average of about 1.5 minutes; the injected bone cement ranged from 3 to 5.5 mL, with an average of 4.2 mL, and there were no spinal nerve injuries or leakage of the cement in the canal. VAS score decreased from 7.65 ± 0.60 before the operation to 2.59 ± 0.28 one day after the operation (P < 0.01); ODI decreased from 62.3 ± 2.18 before the operation to 27.91 ± 1.32 after the operation (P < 0.01). Conclusion: The application of CT-guided PKP combined with the three-dimensional coordinate guidance system has the advantages of accurate puncture, short operation time, less intraoperative bleeding, and low complications. This treatment is safe, reliable, and satisfactory for patients, and is worthy of clinical promotion.
