thank you for your query. our vertebral column (back bone) contains a cavity called the
spinal canal, which has the following parts in descending order- cervical, thoracic, lumbar, sacral; depending upon which part of the canal is forming the cavity. the vertebral column is made up of vertebrae and intervertibral discs in between two subsequent vertebrae. the
spinal cord (a continuation of brain and source of all the nerves supplying the
limbs and trunk) passes through the spinal canal.
your report means there is narrowing (stenosis) of moderate severity in the spinal canal at the level of cervical 5 and 6 vertebra (c5, c6). this stenosis resulted from osteophytes (bony spurs) at the posterior end of
intervertebral disc at that level (usually caused due to chronic traction/
spondylosis etc). due to this stenosis, the spinal cord/ nerves coming out of it are irritated (? compressed), causing the pain and movement restrictions.
moreover, the thoracic/ dorsal spine shows mild chronic
scoliosis, meaning the column is bend towards a side (either right or left) gradually, causing a stretch in the spinal cord and nerves at that level, increasing your symptoms further.
these conditions are managed and treated by a combined team of multi-specialists, consisting of Neurologists, Spine surgeons, orthopedicians, physical medicine specialists and physiotherapists. I would suggest you to visit a multi-speciality hospital having all these facilities for adequate management.
Hope I've been able to satisfy your query. Please don't hesitate to contact me for further clarifications if needed. thank you.
