What is performed during the Transverse Ligament Stress Test?

During the Transverse Ligament Stress Test, the clinical procedure involves applying a posterior translation force to the patient's forehead while stabilizing the axis (C2) vertebra. This is done to assess the integrity of the transverse ligament, which helps to maintain the alignment and stability of the dens of the axis (C2) in relation to the atlas (C1). If the transverse ligament is intact, the movement should not result in excessive motion at the atlantoaxial joint. If there is excessive movement or instability, it suggests that the transverse ligament may be compromised.

The application of posterior pressure on the forehead specifically targets this assessment, as it allows the clinician to gauge the resistance and potential instability present in the cervical spine at that level. Other options do not address the specific mechanics or purpose of the transverse ligament stress test, focusing instead on techniques that do not align with the primary goal of assessing ligamentous integrity at the cervical spine.
