The upper back is composed of the ribs, the 12 thoracic spinal joints and discs and a multitude of muscles involved in trunk motion and shoulder control and power.
Pain in this area is most often caused by poor posture, particularly with our day to day desk and phone/tablet use.
The stiffness caused by this posture can lead to thoracic spinal facet joints becoming locked which is very painful. The ribs can also be impacted and effect rotation and cause breathing disorders.
Growth issues can cause scoliosis which is where the spine grows irregularly and leads to a twist of the thoracic spine. Careful treatment and monitoring of this are is essential to ensure that long term function is preserved.
