Flat spine

Flat spine

According to my Injury classification system, flat spine with no other associated condition, is considered Level 1 Injury, as per the main dysfunction being found at the first Alignment protective layer.

The Spinal column depend on 4 essential curves to maintain its shock absorption properties and overall protection. The idea curve for each section of the spine is 60 degree. There are two primary curves and two secondary curves.

The primary curves are the first ones to be formed during the development of the foetus and is considered the kyphotic sacral and thoracic curves. As the baby begins to crawl and engage on head movements, the lordotic lumbar and cervical curves develops.

Misalignments and poor muscle support may alter the ideal 60-degree curves and impaired the intrinsic protective mechanisms of the spine, eventually predisposing to several conditions ranging from a spastic muscle to degenerative disc disease.

There are certain patterns of misalignment that predisposed to a decrease in the spinal curves (flat spine) diagnosed during the spinal clinical assessment and X-ray analysis.

Anterior superior (AI) Ilium , Internally rotated (IN) Ilium, Posterior rotated sacrum and Posterior vertebral segment.

Swayback deformity is a condition that causes a segment of the spine flatter due to a compensation from a posterior vertebral misalignment. The thoracic section is the most common area for the appearance of this deformity. For instance, a posterior T6 vertebral segment will cause a group of segments above (T5, T4, T3, …) to compensates and drive forward creating the visual flattering and swayback deformity.



Spinal/Pelvic clinical assessment to identify the dysfunctional vertebral segments that contributed to this deformity.

Xray analyses

Anteroposterior (AP) and Lateral spinal views are essential to properly diagnosed and visualise the patterns of dysfunction.


Treatment Protocol

Specific spinal/pelvic adjustments followed by a rehabilitation regime to strengthen the entire soft tissue support of the spine

Depending on the level of deformity and chronicity, minimum 6 weeks to 12 weeks of care is advisable to resolve this condition.
