A thirty-three vertebra column protecting the neuraxis and supporting posture. Degenerative disc disease, stenosis, deformity, and myelopathy define its clinical workload.
A three-dimensional deformity of the growing spine of unknown cause, characterised by lateral curvature and vertebral rotation during adolescence.
Compression or inflammation of a cervical nerve root producing dermatomal arm pain with or without motor and reflex changes.
Degenerative narrowing of the cervical canal producing chronic spinal cord compression and progressive neurological dysfunction.
Displacement of nucleus pulposus material beyond the disc space, commonly causing radiculopathy through compression of a nerve root.
Narrowing of the central canal, lateral recess, or foramen of the lumbar spine producing neurogenic claudication in older adults.
Slippage of one vertebral body on another, typically at L4-5 (degenerative) or L5-S1 (isthmic), producing back pain, radiculopathy, or neurogenic claudication.
