“…The atlantoaxial posterior approach, first proposed by Gallie et al [ 18 ] in 1939, has become the mainstream posterior fixation technique after continuous development and innovation. Nonetheless, in cases with contraindications such as abnormal vertebral artery, posterior atlantoaxial structural fractures, lateral mass fractures, or patients who need a cervical operation in supine position with cardiovascular and respiratory disease, the posterior approach may not be feasible [ 9 , 15 ].…”

“…In 2020 and 2022, we designed a retrospective multiplanar computed tomography-based morphometric study to determine the morphometric characteristics and the potential trajectory of ATCS in adults and children. We comprehensively measured the range of screw lengths of ATCS, as well as screw lateral angles (LAs) and incline angles (IAs), which provide security guarantees for ATCS [ 11 , 15 ]. Our study showed that the longer screw length of ATCS has larger pullout strength.…”

“…On lateral radiographs, all screws are aimed at the superoposterior corner of C1 superior articular process. 15 During the procedure, a 1.0-mm K-wire was used to drill in a specific direction under x-ray fluoroscopy. Once the needle was inserted into the subcortical area in the atlas mass, a 2.5-mm electric drill bit was used to drill along the K-wire, and a 4-mm diameter hollow tension screw was inserted.…”

Objective: To evaluate the biomechanical stability of anterior transarticular crossing screw (ATCS) and compare it with anterior transarticular screw (ATS) which may provide basic evidence for clinical application.Methods: Eight human fresh cadaveric specimens (occiput-C4) were tested with 5 conditions including the intact status, the injury status (type II odontoid fracture), the injury+ATS fixation status (traditional bilateral ATS fixation); the injury+unilateral ATCS fixation status; and the injury+bilateral ATCS fixation status. Specimens were applied to a pure moment of 1.5 Nm in flexion-extension, lateral bending, and axial rotation, respectively. The range of motions (ROMs) and the neutral zones (NZs) of C1 to C2 segment were calculated and compared between 5 status.Results: ATS and ATCS fixations significantly reduced the motions in all directions when compared with the intact and injury statues (p < 0.05). In flexion-extension, the ROMs of ATS, unilateral ATCS, and bilateral ATCS were 4.7° ± 2.5°, 4.1° ± 1.9°, and 3.2° ± 1.2°, respectively. Bilateral ATCS resulted in a significant decrease in ROM in flexion-extension when compared with ATS and unilateral ATCS (p = 0.035 and p = 0.023). In lateral bending and axial rotation, there was no significant difference in ROM between the 3 fixations (p > 0.05). Three fixations resulted in similar NZs in all directions (p > 0.05).Conclusion: ATCS is a biomechanically effective alternative or supplemental method for atlantoaxial instability.

“…The feasibility of the use of anterior transarticular crossing screws (ATCSs) was con rmed in the cadaveric specimen, and this method has been used in clinics. This study has helped surgeons perform ATCS safely and accurately, Liu et al documented the morphometric characteristics of ATCS on radiologic images and provided the range of the angles and lengths of ATCSs on the basis of multiple slides of the coronal and sagittal plane (27).…”

Abstract Background: The aim was to evaluate the effectiveness and safety of transarticular C1–C2 screw fixation (C1C2-TAS) and C1 lateral mass–C2 pedicle screw fixation (C1LM-C2PS) in patients with C1–C2 instability injuries.Methods: This study was a prospective, self-controlled, single-institute study on two fixation techniques for the treatment of atlantoaxial instability caused by injury. From 06/2006 to 02/2017, 118 patients were allocated into two groups: group 1 (C1C2-TAS group) with 52 patients and group 2 (C1LM-C2PS group) with 66 patients. The investigated variables were noted before, during and after surgery. All patients were closely followed up through physical examination and radiological imaging at 3 months postoperatively.Results: There were significant differences in operation time, blood loss, and hospital length-stay between the two groups (p <0.001). Compared with those in the C1LM-C2PS group, the mean operation time was shorter (78.94 vs. 110.91 min; p = 0.0003), blood loss during surgery was lower (122.31 vs. 258.33 ml; p <0.0001) and hospital length-stay was shorter (5.31 vs. 8.34 days; p = 0.0003) in the C1C2–TAS group. The complication of surgery was low with no injury of vertebral artery. After surgery, clinical presentations were significantly reduced and were statistically significant in both groups. The remaining patients showed satisfactory internal fixation in the postoperative radiographs and CT examination.Conclusion: C1C2-TAS and C1LM-C2PS demonstrated effectiveness and safety in the treatment of patients with atlantoaxial instability injury. Notably, C1C2-TAS resulted in shorter surgical time, lower blood loss during surgery and shorter in-hospital stay than C1LM-C2PS.
