What is Grisel syndrome associated with?

Grisel syndrome is primarily associated with C1-C2 subluxation, specifically a postural change that occurs as a result of an upper respiratory infection or other inflammatory processes that involve the upper cervical spine. This condition typically arises due to reflexive muscle spasms in response to irritations or infections in the head or neck area, leading to the misalignment of the atlas (C1) and axis (C2) vertebrae.

This association with C1-C2 subluxation is significant because it highlights the anatomical relationship and biomechanical implications of these vertebrae, as they are crucial for maintaining the stability and function of the cervical region. When there is a disruption at this junction, it can lead to a variety of neurological symptoms and complications, including alterations in cranial nerve function due to the proximity of these vertebrae to major neural pathways.

In contrast, lower back pain, neck stiffness, and shoulder impingement are not directly related to Grisel syndrome. These conditions may involve other areas of the spine or musculoskeletal system but do not reflect the specific cervical subluxation that characterizes Grisel syndrome. This distinction is critical in understanding the implications of cervical spine disorders in chiropractic practice.
