Study Design: Review of the best-validated measures of cervical spine alignment in the sagittal axis.
Objective: Describe the C2-C7 Cobb Angle, C2-C7 sagittal vertical axis, chin-brow to vertical angle, T1 slope minus C2-C7 lordosis, C2 slope, and different types of cervical kyphosis.
Methods: Search PubMed for recent technical literature on radiograph-based measurements of the cervical spine.
Results: Despite the continuing use of measures developed many years ago such as the C2-C7 Cobb angle, there are new radiographic parameters being published and utilized in recent years, including the C2 slope. Further research is needed to compare older and newer measures for cross-validation. Utilizing these measures to determine the degree of correction intraoperatively and postoperatively will enable surgeons to optimize patient-level outcomes.
Conclusion: Cervical spinal deformity can be a debilitating condition characterized by cervical spinal misalignment that affects the elderly more commonly than young populations. Many of these validated measures of cervical spinal alignment are useful in clinical settings due to their ease of implementation and correlations with various postoperative and health-related quality of life outcomes.

Nitrous oxide (NO) has been increasingly used for recreational purposes due to its dissociative and euphoric properties. Exposure to NO results in the deactivation of in vivo vitamin B, leading to subsequent neurological sequelae due to vitamin B deficiency.7 Current management focuses on cessation of exposure and replacement therapy, yet patients may continue to suffer from permanent neurological damage.

Intramedullary spinal cord metastasis (ISCM) is a rare manifestation of renal cell carcinoma (RCC). A 73-year-old man presented with left shoulder pain and left upper extremity weakness for two months. Magnetic resonance imaging (MRI) revealed intramedullary and intradural extramedullary lesions at the C5 level, compressing the spinal cord from the center of the cord and the left ventral side.

Objective: In this study, we aimed to determine the effects of 2-week neuromuscular electrical stimulation (NMES) on quadriceps muscle atrophy and lower extremity motor score in individuals with subacute incomplete cervical spinal cord injury (SCI).
Methods: This stratified randomized controlled trial, conducted in the advanced critical care center of a university hospital, comprised 49 individuals with American Spinal Injury Association (ASIA) impairment scale grade C and D incomplete cervical SCI. The participants were stratified based on the ASIA impairment scale grade and randomly assigned to the control (n = 25) or NMES (n = 24) group.

BACKGROUND The management of unstable atlas fractures remains a subject of ongoing debate and controversy. The conservative surgical treatment commonly involves fusion, resulting in severe loss of cervical spine mobility, and a large incisions and extensive tissue dissection are required. We aim to introduce a novel concept and surgical approach for treating atlas fracture, one that involves minimizing trauma while maintaining mobility of the upper cervical spine without resorting to fusion.
