Key Finding
O-arm navigation significantly reduced surgical preparation time, screw placement time, and fluoroscopy time compared to C-arm navigation while maintaining equivalent accuracy and clinical outcomes in percutaneous sacroiliac screw fixation.
This study is not related to acupuncture. Researchers compared two surgical navigation systems for treating sacral fractures (breaks in the bone at the base of the spine). The study involved 46 patients who received minimally invasive screw placement surgery between April 2021 and October 2022. Nineteen patients had surgery guided by O-arm navigation, while 27 patients received surgery with C-arm navigation guidance. Both groups achieved successful outcomes with complete bone healing and no complications like nerve damage, screw loosening, or loss of fracture alignment during the 6-21 month follow-up period. The O-arm navigation system demonstrated significant advantages in efficiency: it reduced preparation time, screw placement time, and radiation exposure time compared to the C-arm system. Both navigation methods showed similar accuracy in screw positioning and fracture alignment quality, and patients in both groups reported comparable pelvic function scores at their final follow-up appointments. The study concluded that O-arm navigation offers improved surgical efficiency and clearer imaging while maintaining the same safety and effectiveness as C-arm navigation. This research pertains to orthopedic surgery technology rather than acupuncture or Traditional Chinese Medicine, so patients interested in acupuncture treatment should consult qualified practitioners regarding evidence-based approaches for their specific conditions.
This retrospective orthopedic surgery study is not related to acupuncture practice. Researchers compared O-arm versus C-arm navigation systems for percutaneous sacroiliac screw placement in 46 patients with Denis type II sacral fractures (n=19 O-arm, n=27 C-arm). The O-arm group demonstrated significantly shorter intraoperative preparation time, per-screw placement time, and fluoroscopy time (P<0.05). No significant differences were observed in screw position accuracy, fracture reduction quality, healing time (mean 12-month follow-up), or Majeed pelvic function scores between groups (P>0.05). Both groups achieved 100% bony union with no neurovascular injuries or hardware complications. The study concluded O-arm navigation offers superior surgical efficiency with equivalent clinical outcomes. This research has no clinical relevance to acupuncture or Traditional Chinese Medicine practice.
