Abstract

Background

Percutaneous anterior odontoid screw fixation for odontoid fractures remains challenging due to the complex anatomy of the craniocervical junction. We designed a new guide instrument to help with the placement of guide wire, which have achieved satisfying surgical results. The objective of this study is to evaluate the safety and efficacy of this new tool in percutaneous anterior odontoid screw fixation.

Methods

Twenty-nine patients with odontoid fracture were retrospectively evaluated. All patients underwent percutaneous anterior odontoid screw fixation with the traditional guide instrument (n = 13) or the new guide instrument we designed (n = 16). The following clinical outcomes were compared between the two groups: operation time, radiograph times, incision length, blood loss, postoperative hospitalization, postoperative complications, bony union, fixation failure, and reoperation. Radiographs or CT scans were performed at 3, 6 and 12 months after surgery.

Results

There were no significant differences in preoperative demographic data between the two groups. The operation time (56.62 ± 8.32 Vs 49.63 ± 7.47, P = 0.025) and radiograph times (26.54 ± 6.94 Vs 20.50 ± 5.02, P = 0.011) of the designed guide instrument group were significantly lower than those of the traditional guide instrument group. There were no significant differences in incision length (16.08 ± 3.07 Vs 15.69 ± 2.73, P = 0.720), blood loss (16.08 ± 4.96 Vs 17.88 ± 5.98, P = 0.393), postoperative hospitalization (7.15 ± 1.91 Vs 6.88 ± 2.36, P = 0.734), postoperative complications (7.7% Vs 12.5%, P = 1), and bony union (92.3% Vs 93.8%, P = 1) between the two groups. No fixation failure or reoperation occurred in either group.

Conclusions

The top of our designed guide instrument is a wedge-shaped tip with 30° inclination, which has a large contact area with the anterior surface of the cervical vertebra. According to our retrospective study, the guide instrument can reduce the operation time and radiograph times. It has potential clinical value, which needs further testing with a higher level of research design.
