C1-2 hypermobility and its impact on the spinal cord: a finite element analysis

CONCLUSIONS: This FEA revealed significant spinal cord stress during pathological rotation (50°) and lateral translation (5 mm) consistent with values found during severe spinal cord compression and in patients with myelopathy. While this finite element model requires oversimplification of the atlantoaxial joint, the study provides biomechanical evidence that hypermobility within the C1-2 joint leads to pathological spinal cord stress.PMID:38701531 | DOI:10.3171/2024.2.SPINE231327
