OBJECTIVE: To retrospectively assess the feasibility and safety of percutaneous minimally invasive pedicle screw fixation for cervical @entity174 using intraoperative three-dimensional fluoroscopy-based navigation. METHODS: Thirty @entity1 admitted from April 2012 to May 2014 in Beijing Jishuitan Hospital with cervical @entity174 underwent pedicle screw fixation using intraoperative three-dimensional fluoroscopy-based navigation, with 8 @entity1 using minimally invasive technique (CAOS-MIS group), and the other 22 @entity1 using conventional open approach (CAOS-open group). Operative time, @entity190 and @entity260 were recorded. Screw positions were studied by postoperative CT scan. All @entity1 were followed up for at least 6 months. Neck visual analogue score (VAS) and American @entity3510 Association (ASIA) classification were evaluated preoperatively and at 6-month follow-up. Independent-sample t test and Chi-Square test were used for statistical analysis. RESULTS: Operation time was (139    18) minutes and @entity190 was (73    40) ml in CAOS-MIS group and correspondingly (154    42) minutes utes and (296    171) ml in CAOS-open group. The @entity190 in CAOS-MIS group was significantly lower than that in CAOS-open group (t = 5.695, P < 0.01). No screw-related @entity1317 was observed. Thirty-four screws were placed in CAOS-MIS group with 28 screws (82.4%) classified as Grade I, meanwhile in CAOS-open group 108 screws were placed with 96 screws (88.9%) classified as Grade I. There was no statistical difference between the two groups (  (2) = 0.998, P > 0.01). VAS score showed no statistical difference preoperatively (t = 0.334, P > 0.01), however statistical difference existed at 6 months follow-up (t = 4.111, P < 0.01) with (0.4    0.5) in CAOS-MIS group and (1.5    0.7) in CAOS-open group. There were 1 @entity1 from class B to improve to D, 1 case from D to E in CAOS-MIS group, and 1 @entity1 from class A to improve to B, 1 case from B to D, 2 cases from C to D, 3 cases from D to E in CAOS-open group 6 months after surgery. Cervical X-ray demonstrated @entity174 healed well in all cases at 6 months follow-up. CONCLUSION: It is feasible and safe for percutaneous minimally invasive pedicle screw fixation for cervical @entity174 using intraoperative three-dimensional fluoroscopy-based navigation, which can also decreases the incidence of @entity282 .
