Does a block vertebra have any impact on the concerned segment of spine?
The fused vertebrae behave as a single vertebra. This results in hypermobility of the adjacent vertebrae and is accompanied by ligament laxity. These adjacent vertebral joints are secondarily prone for early spondylosis.
Is this significant for airway manipulation?
Documentation of a cervical block vertebra enables any physician who needs to intubate the patient to be way of the condition. Hypextension of the neck is essential for endotracheal intubation. The concerned physician can be careful in manipulation of the neck thereby preventing any undue secondary disc herniation.
