Summary
Intraoperative 3D navigation for posterior cervical foraminotomy (PCF) offers comparable outcomes to conventional fluoroscopy. While both methods provide symptom relief, 3D navigation did not show a clear advantage, suggesting technical complexity should guide surgical choice.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Minimally Invasive Procedures
Background:
- Unilateral monosegmental radiculopathy is treated with posterior cervical foraminotomy (PCF).
- Conventional fluoroscopy is standard for PCF but has limitations, particularly in obese patients and lower cervical spine procedures.
- The efficacy of intraoperative 3D navigation in PCF remains to be fully elucidated.
Purpose of the Study:
- To compare the outcomes of PCF using intraoperative 3D navigation versus conventional fluoroscopy.
- To assess the effectiveness of 3D navigation in improving surgical precision and patient outcomes in PCF.
Main Methods:
- Retrospective study comparing 42 patients undergoing PCF with 3D navigation and 63 patients with conventional fluoroscopy.
- Patients were stratified into upper (C3-C6) and lower (C6-T1) cervical spine subgroups.
- Statistical analysis included Mann-Whitney U and Friedman tests.
Main Results:
- Both groups showed significant postoperative symptom improvement with no significant neurological differences.
- Subgroup analyses for upper and lower cervical spine did not reveal significant differences between the two methods.
- A significant difference in blood loss was observed only in the C3-C6 group, favoring the 3D navigation group.
Conclusions:
- Intraoperative 3D navigation is a viable tool for PCF, achieving significant symptom relief.
- Outcomes with 3D navigation appear comparable to conventional fluoroscopy, lacking statistically significant advantages.
- The technical complexity of 3D navigation should be a consideration when selecting the surgical approach for PCF.
