Exams for cervical spine instability

The main idea here is recognizing tests that assess cervical spine stability, specifically the atlantoaxial region. The Sharp-Purser test targets potential instability of the atlas on the axis due to transverse ligament compromise. In this test, the clinician stabilizes the axis (C2) and applies a gentle posterior force to the head to cause a reduction of any anterior displacement of the atlas on the dens. If a clunk is felt and symptoms improve with this gentle correction, that suggests unstable atlantoaxial mechanics from transverse ligament involvement.

Other tests listed serve different purposes: Spurling’s test screens for nerve-root compression or radiculopathy from foraminal stenosis; Allen’s test checks blood flow in the arm; Roo’s test evaluates thoracic outlet syndrome. They don’t specifically evaluate upper cervical instability, so they’re not the best fit for this scenario.
