Atlas Roll is a frontal plane rotation (roll) of C1 vertebrae
Right Laterality of Atlas. Note the concurrent head tilt to the right
clinically observed with Laterality (Roll/Frontal Plane Rotation) of the Atlas.
Dental Implications:
Distortions in the position of the maxilla (e.g., malocclusions) can destabilize the Atlas (C1)
When the Maxilla is in a rolled position (deviated on the frontal plane):
- The Atlas Rolls (Attilio)
- The Axis distortion destabilizes the entire spine (increased scoliotic and kyphotic curves (Korbmacher et al) Note: My current research suggests that frontal plane distortions in the Atlas (e.g. an Atlas Roll) only destabilizes the spine in the frontal plane (e.g., augmenting the scoliotic curves).
- The distortions in the spinal curves destabilizes the pelvis in both the frontal (rolls) and transverse planes (yaws) (Seemann) Note: My current research suggests that frontal plane distortions in the spinal cord only distort the pelvis in the frontal plane (e.g., pelvic tilt).
- The tilt (unleveling) in the pelvis can result in medial knee pain (at the level of the pes anseranus) and lateral ankle pain (peroneal muscles)
- If the Atlas Roll is severe enough, it can result in symptoms similar to those seen in degenerative neurological disorders (Thomas and Wood, 1992, Case History).
Postural Distortional Pattern seen in a Pure C1 Roll Right*
C1 Roll Right
- Pelvic Tilt Right (High Left Pelvic Rim)
- Tight Left Hamstrings (painful pes anseranus)
- Tight Left Gastrocneumius and Soleus
Postural Distortional Pattern seen in a Pure C1 Roll Left*
C1 Roll Left
- Pelvic Tilt Left (High Right Pelvic Rim)
- Tight Right Hamstrings (painful pes anseranus)
- Tight Right Gastrocnemius and Soleus
* = Any deviation in the pattern of symptoms indicates the presence of a Mixed Postural Distortional Pattern
