颈椎病（cervical spondylosis）是由于颈椎间盘退行性病变、颈椎骨质增生所引起的一系列临床症状的综合征，是脊椎病的一种。

Spondylosis (from Ancient Greek σφόνδυλος spóndylos, "a vertebra", in plural "vertebrae – the backbone") is degenerative osteoarthritis of the joints between the center of the vertebrae or neural foramina. If this condition occurs in the facet joints, it can be considered facet syndrome. If severe, it may cause pressure on nerve roots with subsequent sensory or motor disturbances, such as pain, paresthesia, and muscle weakness in the limbs.
