“…Consequently, most clinical and anatomical studies have focused on avoiding vertebral artery injury in upper cervical surgery. However, vertebral artery injury can also occur during posterior cervical foraminotomy in the subaxial spine [3,11]. The incidence of vertebral artery injury is predicted to increase because a growing number of surgeons are performing endoscopic cervical foraminotomies [12,13].…”

Objective Vertebral artery injuries during posterior cervical foraminotomy are rare, but can be fatal. Therefore, we investigated the anatomical correlation between the lateral recess and the vertebral artery. Methods On axial cuts of cervical magnetic resonance imaging from 108 patients, we measured the distance between the vertebral arteries and the medial border of the facet joints. The anatomical vertebro-facet distance (AVFD), surgical vertebro-facet distance (SVFD), and vertebro-facet angle (VFA) were measured. Results The mean AVFD values on the right side at the C3–4, C4–5, C5–6, and C6–7 levels showed statistically significant differences. On the right side, the mean SVFD values were equivalent to the AVFD values. The mean values of the VFA on the right side at all levels showed statistically significant differences. For all measurements, the greatest differences were seen between the C5–6 and C6–7 levels, and higher levels were associated with smaller distances from the lateral recess. The mean values of the AVFD on the right and left sides showed statistically significant differences at all levels, and the distances on the left were smaller than those on the right. Conclusion The vertebral artery is closer to the lateral recess at higher cervical levels than at lower cervical levels. The largest distances were found at the C5–6 and C6–7 levels, and the left vertebral arteries were closer to the lateral recess than the right vertebral arteries.

“…Kim et al reported a case of spinal dural injury caused by the intraoperative drilling process, 24 and Stephen et al reported a case of vertebral artery injury during posterior cervical surgery. 25 Based on the above complications, Nkamura S et al designed an internal retractor to avoid nerve damage, but it was di cult to popularize. 26 The technique of anchoring the projection point on the inner upper edge of the pedicle that was used in this study was performed under direct endoscopic vision.…”

Purpose To describe a new modified MI-PCF, and evaluate its feasibility/short-term efficacy.Method Data from 21 patients with cervical spondylotic radiculopathy who were treated with the modified MI-PCF were collected. Patients’ preoperative/postoperative neck and arm pain were evaluated by the VAS, JOA and modified MacNab scores. The postoperative decompression effect was evaluated by CT and MRI. Cervical CT was performed for 3D reconstruction of the patients’ cervical spine. A cross section through the intersection of the inner and upper edges of the pedicle was used to measure the distance between the projection point on the inner upper edge of the C3-7 pedicle and the V point (a)/the midline of the spinous process (b). This distance was also measured in human cadavers(c)/(d).Result The operation was successful in all patients. The mean operative duration was 70.1± 20.0 min, and the mean number of fluoroscopies was 4.0± 0.9 times. The VAS, JOA and modified MacNab scores were all significantly improved. The values of a, b, c, and d for C3-7 were 1.43 ± 0.07 ~ 4.98 ± 0.22 mm, 14.00 ± 0.29 ~ 16.35 ± 0.45 mm, 1.47± 0.08 ~ 5.08 ± 0.25 mm, and 14.04 ± 0.32 ~ 16.36± 0.43 mm, respectively.Conclusion The number of fluoroscopies and the operative duration were reduced by the anchoring of the projection point on the inner upper edge of the pedicle. Overall this study describes a new method for positioning and verification of the V point in MI-PCF.
