Abstract:
Objective To analyze the clinical efficacy of three-dimensional(3D)C-arm real-time fluoroscopic navigation-as-sisted odontoid screw fixation for treating type Ⅱ odontoid fractures.Methods Clinical data from 16 patients with type Ⅱ od-ontoid fractures treated using 3D C-arm real-time fluoroscopic navigation-assisted screw fixation were retrospectively ana-lyzed.The impact of intraoperative 3D C-arm navigation assistance on screw placement accuracy and clinical outcomes was eval-uated.Results The cohort consisted of 10 males and 6 females,with a mean age of(48.37±2.42)years.The average time from injury to surgery was(5.00±1.25)days.Intraoperatively,the mean number of fluoroscopic exposures was 8.5 times.The aver-age operative time was(125.26±18.31)min,with an average blood loss of(89.00±16.49)mL.No neurovascular complications occurred intraoperatively or postoperatively.The screw placement accuracy rate was 100％.Patients were followed up for a mean duration of(24.52±5.38)months,achieving a 100％bony fusion rate.At the final follow-up,cervical flexion range of mo-tion was(95.21±9.52)°,rotation range of motion was(103.66±10.73)°,and VAS and NDI scores were 1.04±0.03 and 7.51±1.26,respectively.Conclusion Utilizing 3D C-arm real-time fluoroscopic navigation assistance for odontoid screw fixation in type Ⅱ odontoid fractures improves screw placement accuracy and yields satisfactory outcomes in both radiological assessment and clinical efficacy.
