Cervical Spondylosis Introduction

Home/Bone & Joint Disorders/Cervical Spondylosis Introduction


Cervical Spondylosis is characterised by abnormal growth of bones (osteophytes) of the spine in the neck region (cervical vertebra), degeneration, herniation (protrusion) and deposition of calcium in the cushions (known as intervertebral discs) between the cervical vertebrae.


In middle-aged and elderly persons, some degree of degenerative changes in the cervical spine is a common finding and it usually does not produce any symptom. Degeneration of the cushions between vertebrae may compress the nerves and cause symptoms of cervical spondylosis. Usually, the disc between fifth and sixth (C5/ C6), sixth and seventh (C6/ C7) or fourth and fifth (C4/ C5) cervical vertebra are affected.
