Summary: The objective of this study is to establish a new parameter that can be measured on x-ray images to complement the description of the sagittal alignment of the craniocervical junction. The authors anticipate that this new parameter will enhance surgeons' understanding and guidance in intraoperative reduction and postoperative evaluation of patients with atlantoaxial instability.

Summary: This study retrospectively analyzed consecutive patients who underwent transoral odontoidectomy for basilar invagination and atlantoaxial dislocation. The results showed that with proper patient selection, transoral odontoidectomy can be safely performed in a limited-resource setting and achieve significant improvement.

Summary: This study assessed the role of the triangular area (TA) in measuring the severity of brain stem compression in craniovertebral junction (CVJ) deformity. The results showed that the TA was larger in the CVJ deformity group compared to the healthy control group, and after surgery, the TA showed varying degrees of improvement, which correlated with the efficacy of surgery.

Summary: The study assessed the morphologic features of the subaxial cervical spine in basilar invagination (BI) patients to provide information for accurate screw placement. BI patients have wider pedicle and laminar structures in the subaxial cervical spine, but similar length of pedicle, laminar, and lateral mass compared to the general population.

Summary: The study introduced a new surgical protocol for safe and accurate placement of C1 lateral mass screws in patients with atlas assimilation, basilar invagination, and atlantoaxial instability. By following specific steps, including ligament release, exposure of the invaginated lateral mass, and protection of the vertebral artery, high screw accuracy and minimal complications were achieved.

Summary: This study retrospectively analyzed the outcomes of a head frame reduction and atlantoaxial arthrodesis technique for the treatment of reducible basilar invagination and atlantoaxial dislocation. The results showed significant radiological and clinical improvements, with solid bony fusion observed in the majority of patients. The head frame reduction technique was found to be a simple and effective treatment option.

Summary: This retrospective study evaluated the validity of three radiologic measurements for the diagnosis of basilar invagination (BI), and obtained optimal cutoff values. The results showed that these measurements are reliable for the diagnosis of BI, especially when adjusted for sex and specific radiologic measurement.

Summary: This study examined the correlation between syrinx resolution and occipitoaxial sagittal alignment after posterior reduction and fixation in BI-AAD patients with syringomyelia. The results showed that structural remodeling of the craniovertebral junction and occipitoaxial realignment contributed to syringomyelia resolution in these patients.

Summary: This study focused on craniocervical abnormalities in patients with osteogenesis imperfecta (OI) type V, highlighting the importance of regular screening for basilar invagination and cervical kyphosis in this population. Some patients required surgical intervention, and there was no clear correlation between the severity of craniocervical abnormalities and the OI phenotype.

Summary: This study focused on investigating the foramen magnum angle (FMA) and its relationship with other craniocervical parameters in cases of congenital basilar invagination (BI), demonstrating the significance of FMA in reflecting the degree of BI and highlighting clivus hypogenesis as a reason for excessive tilt of the foramen magnum.

Summary: A 45-year-old woman presented with severe neck pain and gait imbalance, and was successfully treated with anterior distraction and posterior stabilization surgery for irreducible atlantoaxial dislocation. The patient achieved independence in walking and complete recovery after 2 years of follow-up. Proper investigation and surgical planning are crucial for desirable long-term outcomes in cases involving anomalies of the craniovertebral junction.

Summary: Through follow-up X-ray examinations of 200 cervical surgery patients, it was found that CVA is the most predictable parameter for C2-C7 SVA, and upper cervical parameters are more explanatory for C2-C7 SVA changes than lower cervical parameters.

Summary: A systematic review found that preserving the C1 anterior arch improves postodontoidectomy spine stability. Transoral approaches and endoscopic endonasal approaches show comparable outcomes and complication rates.
