Objective:
This study aims to investigate the clinical application value of ultrasonography-computed tomography (CT) fusion navigation technology in bone tumor biopsy surgery.
Methods:
Thirty patients with bone tumors requiring biopsy surgery were randomly assigned to either the U-C group (ultrasonography-CT group; n = 15) or the control group (n = 15). The U-C group used ultrasonography-CT fusion navigation technology for real-time localization of the biopsy needle, whereas the control group relied on intraoperative C-arm fluoroscopy for localization. The success rate of the surgeries, the number of radiation exposures during the procedure, surgical time, and intraoperative blood loss were compared between the 2 groups.
Results:
The number of intraoperative radiation exposures in the U-C group was 2 versus 7 in the control group (P < 0.05), showing significant differences between the 2 groups. The success rate of biopsies in the U-C group and control group was 100% (P > 0.05), the mean operative time was 45 ± 9 minutes versus 42 ± 13 minutes (P > 0.05), and intraoperative bleeding volume was 10 ± 4 mL versus 11 ± 5 mL (P > 0.05), all showing no significant differences between the 2 groups.
Conclusions:
The real-time localization of the biopsy needle in bone tumor biopsy surgery using ultrasonography-CT fusion navigation technology can significantly reduce intraoperative radiation exposure for both patients and surgeons during the procedure. Consequently, this technique holds certain clinical applicability.
