title: The cellular and molecular biology of the intervertebral disc: A clinician's primer.
abstract: Clinicians routinely encounter patients suffering from both degenerative and acute spinal pain, often as a consequence of pathology affecting the intervertebral disc (IVD). The IVD is a complex structure essential to spinal function and is subject to degenerative disease and injury. However, due to the complexity of spinal pain syndromes it is often difficult to determine the extent of the IVD's contribution to the genesis of spinal pain. The location of the IVD is within close proximity to vital neural elements and may in the event of pathological change or injury compromise those structures. It is therefore important that clinicians performing manual therapy understand the cellular and molecular biology of the IVD as well as its clinical manifestation of degeneration/injury in order to safely manage and appreciate the role played by the disc in the development of mechanical spinal pain syndromes.
