What can be one of the consequences of a compromised transverse ligament?

• A. Increased cervical extension
• B. Increased cervical flexion instability
• C. Increased range of motion
• D. Reduced pain perception

Answer: (B)

A compromised transverse ligament can lead to increased cervical flexion instability due to its crucial role in stabilizing the atlas (the first cervical vertebra) relative to the axis (the second cervical vertebra). The transverse ligament prevents excessive forward motion of the atlas on the axis during head movements, especially flexion. When this ligament is compromised, it fails to provide adequate support, which can result in abnormal motion between the C1 and C2 vertebrae.

This instability can compromise the alignment of the cervical spine and potentially lead to catastrophic consequences, such as neurological deficits or vertebrobasilar insufficiency. Understanding the importance of the transverse ligament in maintaining cervical stability highlights the need for robust evaluation and treatment strategies when dealing with suspected compromise of this structure.
