Complications
A major problem related to this disease is vertebrobasilar insufficiency. This is a result of the vertebral artery becoming occluded as it passes up in the transverse foramen. The spinal joints become stiff in cervical spondylosis. Thus the chondrocytes which maintain the disc become deprived of nutrition and die. The weakened disc bulges and grows out as a result of incoming osteophytes. A ‘drop attack’ in older people is a sign of vertebrobasilar insufficiency, which is the cause of 25% of the strokes and TIA’s in the USA.
